Abstract:
Control by external driving of the heat fluxes present in nanoscale devices is known as thermal resonance (TR). In this work we study the relationship between this phenomenon and interface thermal resistance present in a one-dimensional system composed of two dissimilar anharmonic oscillator lattices interacting by means of a harmonic, time-modulated coupling. We determined that the external driving frequency at which the heat flux reaches its maximum value, and thus the TR set in, is the same at which the interface thermal resistance attains its minimum value. The dependence of this relationship on the variation of some structural parameters such as the temperature, temperature difference, and coupling constants, was also studied. The overlap of the phonon bands associated with each side determines the frequency range in which resonance emerges. Considering the dependence on the system size, it is inferred that TR, as well as the minimum in the thermal resistance, will exist in the large system-size limit.

RLC Circuit as a Damped Oscillator
Consider a series RLC circuit. Here, the presence of resistance in the circuit leads to energy loss due to joule heating in the resistance. Therefore, the total electromagnetic energy in the circuit is no longer constant and decreases with time. Since the magnitude of charge, current, and potential difference continuously decreases, their oscillations are said to be damped. This is...
