Light-powered soft steam engines for self-adaptive oscillation and biomimetic swimming

Oscillation plays a vital role in the survival of living organisms in changing environments, and its relevant research has inspired many biomimetic approaches to soft autonomous robotics. However, it remains challenging to create mechanical oscillation that can work under constant energy input and actively adjust the oscillation mode. Here, a steam-driven photothermal oscillator operating under constant light irradiation has been developed to perform continuous or pulsed, damped harmonic mechanical oscillations. The key component of the oscillator comprises a hydrogel containing Fe3O4/Cu hybrid nanorods, which can convert light into heat and generate steam bubbles. Controllable perturbation to the thermomechanical equilibrium of the oscillator can thus be achieved, leading to either continuous or pulsed oscillation depending on the light intensity. Resembling the conventional heat steam engine, this environment-dictated multimodal oscillator uses steam as the working fluid, enabling the design of self-adaptive soft robots that can actively adjust their body functions and working modes in response to environmental changes. An untethered biomimetic neuston-like robot is further developed based on this soft steam engine, which can adapt its locomotion mechanics between uniform and recurrent swimming to light intensity changes and perform on-demand turning under continuous light irradiation. Fueled by water and remotely powered by light, this unique hydrogel oscillator enables easy control over the oscillation dynamics and modes, offering an effective approach to self-adaptive soft robots and solar steam engines.

Energy exchange in globally coupled mechanical phase oscillators

We study the stationary dynamics of energy exchange in an ensemble of phase oscillators, coupled through a mean-field mechanical interaction and added with friction and an external periodic excitation. The degree of entrainment between different parts of the ensemble and the external forcing determines three dynamical regimes, each of them characterized by specific rates of energy exchange. Using suitable approximations, we are able to obtain analytical expressions for those rates, which are in satisfactory agreement with results from numerical integration of the equations of motion. In some of the dynamical regimes, the rates of energy exchange show nontrivial dependence on the friction coefficients --in particular, non-monotonic behavior and sign switching. This suggests that, even in this kind of stylized model, power transfer between different parts of the ensemble and to the environment can be manipulated by a convenient choice of the individual oscillator parameters.

Sandpile cascades on oscillator networks

The BTW sandpile model of cascading dynamics forms a cornerstone for our understanding of failures in systems ranging from avalanches and forest fires to power grids and brain networks. The latter two are examples of oscillator networks, yet the BTW model does not account for this. Here we establish that the interplay between the oscillatory and sandpile dynamics can lead to emergent new behaviors by considering the BTW sandpile model on a network of Kuramoto oscillators. Inspired by high-level objectives in the power grids, we aim to leverage this interaction to maximize synchronization, maximize load, and minimize large cascades. We assume that the more out-of-sync a node is with its neighbors, the more vulnerable it is to failure so that a node's capacity is a function of its local level of synchronization. And when a node topples, its phase is reset at random. This leads to a novel long-time oscillatory behavior at an emergent timescale. The bulk of an oscillatory cycle is spent in a build-up phase where oscillators are fully synchronized, and cascades are largely avoided while the overall load in the system increases. Then the system reaches a tipping point where, in contrast to the BTW model, a large cascade triggers an even larger cascade, leading to a "cascade of cascades," which can be classified as a Dragon King event, after which the system has a short transient dynamic that restores full synchrony. This coupling between capacity and synchronization gives rise to endogenous cascade seeds in addition to exogenous ones, and we show their respective roles in the Dragon King events. We establish the phenomena from numerical studies and develop the accompanying mean-field theory to locate the tipping point, calculate the amount of load in the system, determine the frequency of the emergent long-time oscillations and find the distribution of cascade sizes during the build-up phase.

Correlation Functions of the Anharmonic Oscillator: Numerical Verification of Two-Loop Corrections to the Large-Order Behavior

Ludovico T. Giorgini, Ulrich D. Jentshura, Enrico M. Malatesta, Giorgio Parisi, Tommaso Rizzo, Jean Zinn-Justin. Recently, the large-order behavior of correlation functions of the $O(N)$-anharmonic oscillator has been analyzed by us in [L. T. Giorgini et el., Phys. Rev. D 101, 125001 (2020)]. Two-loop corrections about the instanton configurations were obtained for the partition function, and the two-point and four-point functions, and the derivative of the two-point function at zero momentum transfer. Here, we attempt to verify the obtained analytic results against numerical calculations of higher-order coefficients for the $O(1)$, $O(2)$, and $O(3)$ oscillators, and demonstrate the drastic improvement of the agreement of the large-order asymptotic estimates and perturbation theory upon the inclusion of the two-loop corrections to the large-order behavior.

Energy Transport in 1-Dimensional Oscillator Arrays With Hysteretic Damping

Energy transport in 1-dimensional oscillator arrays has been extensively studied to date in the conservative case, as well as under weak viscous damping. When driven at one end by a sinusoidal force, such arrays are known to exhibit the phenomenon of supratransmission, i.e. a sudden energy surge above a critical driving amplitude. In this paper, we study 1-dimensional oscillator chains in the presence of hysteretic damping, and include nonlinear stiffness forces that are important for many materials at high energies. We first employ Reid's model of local hysteretic damping, and then study a new model of nearest neighbor dependent hysteretic damping to compare their supratransmission and wave packet spreading properties in a deterministic as well as stochastic setting. The results have important quantitative differences, which should be helpful when comparing the merits of the two models in specific engineering applications.

Inferring the connectivity of coupled chaotic oscillators using Kalman filtering

Inferring the interactions between coupled oscillators is a significant open problem in complexity science, with multiple interdisciplinary applications. While the Kalman filter (KF) technique is a well-known tool, widely used for data assimilation and parameter estimation, to the best of our knowledge, it has not yet been used for inferring the connectivity of coupled chaotic oscillators. Here we demonstrate that KF allows reconstructing the interaction topology and the coupling strength of a network of mutually coupled Rössler-like chaotic oscillators. We show that the connectivity can be inferred by considering only the observed dynamics of a single variable of the three that define the phase space of each oscillator. We also show that both the coupling strength and the network architecture can be inferred even when the oscillators are close to synchronization. Simulation results are provided to show the effectiveness and applicability of the proposed method.

Phase reconstruction from oscillatory data with iterated Hilbert transform embeddings -- benefits and limitations

In the data analysis of oscillatory systems, methods based on phase reconstruction are widely used to characterize phase-locking properties and inferring the phase dynamics. The main component in these studies is an extraction of the phase from a time series of an oscillating scalar observable. We discuss a practical procedure of phase reconstruction by virtue of a recently proposed method termed \textit{iterated Hilbert transform embeddings}. We exemplify the potential benefits and limitations of the approach by applying it to a generic observable of a forced Stuart-Landau oscillator. Although in many cases, unavoidable amplitude modulation of the observed signal does not allow for perfect phase reconstruction, in cases of strong stability of oscillations and a high frequency of the forcing, iterated Hilbert transform embeddings significantly improve the quality of the reconstructed phase. We also demonstrate that for significant amplitude modulation, iterated embeddings do not provide any improvement.

Confined Klein-Gordon oscillator in cosmic string spacetime with uniform cosmic screw dislocation; position-dependent mass and torsion effect

We study the Klein-Gordon (KG) oscillator in a cosmic string spacetime with a uniform cosmic screw dislocation (torsion). We start with a confined (in a Cornell-type potential) KG-oscillator and report the torsion effect on the exact energy levels. We observe shifts/dislocations of the energy levels along the torsion's parameter $% \delta $-axis by $\delta =\ell /k_{z};\,\ell =0,\pm 1,\pm 2,\cdots $. Such energy levels shifts/dislocations manifestly yield energy levels crossings (i.e., occasional degeneracies). Moreover, we observe eminent energy levels clusterings when $\left\vert \delta \right\vert >>1$, for each value of the magnetic quantum number $\ell $. To find out parallel systems that admit invariance and isospectrality with the confined KG-oscillator, we discuss the KG-oscillator in a deformed cosmic string spacetime background with a uniform cosmic screw dislocation. Such parallel systems are found to inherit the same effects as above. Yet, we suggest a new recipe for position-dependent mass (PDM) KG-oscillator using the PDM-momentum operator of Mustafa and Algadhi \cite{Mustafa Algadhi 2019}. Two PDM illustrative examples are used, a power-law type PDM, and an exponentially growing PDM. For the exponentially growing PDM, we show that such a PDM introduces a Cornell-type confinement as its own byproduct. Hereby, we observe clustering of the energy levels, as the PDM parameter $\xi $ grows up, but no energy levels crossing are found feasible for a fixed torsion parameter value.

DIY Sub Oscillator #MusicMonday

Just in case your synth rig needs a sub oscillator, here’s a DIY project from Analog Labs Swiss:. This is an easy DIY Sub Oscillator project I’ve made for my Behringer Crave synth but it’ll work for Euroracks also. It tracks a Sawtooth or Triangle signal (10Vpp with 0 offset) or a simple Square wave and output a -1 and a -2 octaves down Square waves. Avoid PWM signals. It’ll not good at traking them. It was tested at 9V and 12V and works well with Crave & Neutron Synths from Behringer but also with Eurorack’s VCO. CD4013 is powered from 0 and 9V (or 12V). The 100k linear potentiometer acts as a mixer to blend the 2 sub osc signal output. At 50% position, it’ll output the famous SH-101 Pulse sub oscillator.

Energy implications of a load depending on geometrical configurations in an oscillator

Elena Campillo, Jimena de Hita, Almudena Martínez, Miguel León, Laura Morón, Andrei Sipos, Daniel Heredia, Javier Domingo, Rubén González. This paper studies, for a specific oscillatory system composed by a pendulum connected to a seesaw, how the geometry of the different mechanisms of energy introduction conditions the resulting movement, to achieve both a greater amplitude of oscillation due to a change of velocity and an acceleration in its movement. The different configurations that give rise to the acceleration of motion are therefore analyzed. The study is carried out from a kinematic point of view, theoretically simulating an energy increase in the system and analyzing its response in terms of angular velocity and of modification of apparent weight. Subsequently, the force diagram necessary to generate the accelerated motion is analyzed. The magnitude of the external force to be applied and its dependence on the direction and angular instant in which it are exerted is evaluated. It is observed how for some specific configurations this magnitude is negative, implying that the system is capable of accelerating when subjected to a brake or load on it.

Collective dynamics of phase oscillator populations with three-body interactions

Many-body interactions between dynamical agents have caught particular attention in recent works that found wide applications in physics, neuroscience, and sociology. In this paper we investigate such higher order (nonadditive) interactions on collective dynamics in a system of globally coupled heterogeneous phase oscillators. We show that the three-body interactions encoded microscopically in nonlinear couplings give rise to added dynamic phenomena occurring beyond the pairwise interactions. The system in general displays an abrupt desynchronization transition characterized by irreversible explosive synchronization via an infinite hysteresis loop. More importantly, we give a mathematical argument that such an abrupt dynamic pattern is a universally expected effect. Furthermore, the origin of this abrupt transition is uncovered by performing a rigorous stability analysis of the equilibrium states, as well as by providing a detailed description of the spectrum structure of linearization around the steady states. Our work reveals a self-organized phenomenon that is responsible for the rapid switching to synchronization in diverse complex systems exhibiting critical transitions with nonpairwise interactions.
