“…When pumped with a monochromatic signal, the microbridge acts as a hotspot, oscillates between superconducting phase and normal conducting phase resulting in thermal self-oscillations. Self-oscillations arising from thermally-induced instabilities have also been reported in other nanodevices such as in thermo-optic nanocavities [37], doped silicon resonator nanopillars [38], carbon schwarzite based phonon nanocapacitor [39] and carbon nanotube based NEMS resonators [40], as well as in optical parametric oscillators [41].…”

Nonlinear phenomena in superconducting resonator circuits are of great significance in the field of quantum technology. We observe thermal self-oscillations in a monolayer graphene flake coupled to Molybdenum-Rhenium superconducting resonator. The graphene flake forms a SINIS junction coupled to the resonator with strong temperature dependent resistance. In certain conditions of pump power and frequency, this nonlinearity leads to thermal self-oscillations appearing as sidebands in cavity transmission measurements with strong temperature dependence and gate tunability. The experimental observations fit well with theoretical model based on thermal instability. The modelling of the oscillation sidebands provides a method to evaluate electron phonon coupling in disordered graphene sample at low energies.

“…In addition, the HGS can be utilized to build the phononic rectifier, in which asymmetric phonon transport can be achieved in different heat flow directions [96]. Furthermore, the coherent phonon state can be generated by the self-synchronization phenomenon via thermal noise [105] or by pulsed laser in the optomechanical system [106,107].…”

Recently, emerging phonon phenomena have been discovered and rapidly developed, which have become an active hot research topic. In this review article, we present state-of-the-art advances in several fascinating phonon transport phenomena. First, we summarize the recent progress on the wave nature of phonons, including phonon coherence and its effects on thermal conductivity and the topological properties of phonons. Then, we discuss the particle nature of phonons, including the weak coupling of phonons and the high-order phonon anharmonicity. Finally, we present the summary and a brief outlook. This review presents the advanced understanding of some emerging phonon phenomena in solid materials, which provides new opportunities for further advancement in a wide variety of applications.

“…The system is quenched at zero time by switching on the cavity field. R(t) evolves from zero to a high value (∼1) for a relatively large |G|/κ∼ 0.04, while R(t) exhibits an 'overshoot' behavior for |G|/κ∼ 0.01 [44]. The transient entropy production rates µ b1,2 (t) and µ a (t) decrease with time and then remain to a stationary state, as shown in figure 4(b).…”

Clock synchronization is critically important in positioning, navigation and timing systems. While its performance has been intensively studied in a wide range of disciplines, much less is known for the fundamental thermodynamics of clock synchronization‒what limits the precision and how to optimize the energy cost for clock synchronization. Here, we report the first experimental investigation of two stochastic autonomous clocks synchronization, unveiling the thermodynamic relation between the entropy cost and clock synchronization in an open cavity optomechanical system. Two interacting clocks are synchronized spontaneously owing to the disparate decay rates of hybrid modes by engineering the controllable cavity-mediated dissipative coupling. The measured dependence of the degree of synchronization on the overall entropy cost exhibits an unexpected non-monotonic characteristic, while the relation between the degree of synchronization and the entropy cost for the synchronization is monotonically decreasing. The investigation of transient dynamics of clock synchronization exposes a trade-off between energy and time consumption. Our results demonstrate the possibility of clock synchronization in an effective linear system, reveal the fundamental relation between clock synchronization and thermodynamics, and have a great potential for precision measurements, distributed quantum networks, and biological science.
