- Abstract: Cavity modulation of interacting molecular vibrational modes promises an expanded role of the characteristic vibrations to act as spectroscopic markers. In addition to the intrinsic, inter-mode and extrinsic, cavity-mediated inter-mode delocalization, the vibrational modes undergo multiscale relaxation due to reservoir vibrations. Two complementary coherent multidimensional spectroscopic techniques are presented, which reveal the dynamical nature of the mode correlations in the presence relaxation. Simulations are presented for finite laser pulses. The chosen cavity-vibron mode coupling strengths fall within the range of inter-vibrational mode coupling, hinting at a parameter regime where vibrational energy dispersal can be controlled. It is highlighted that the cavity manipulation of vibrational double excitations, namely, overtone and combination states, can offer deeper insights into the collective mode dynamics. These observations set the ground for cavity-controlled spectroscopic investigation of mode-selective dynamics, where localized electromagnetic modes function as an effective few-body coupler of vibrations.

We report on the switching dynamics of both single and coupled VO2-based oscillators, with resistive and capacitive coupling, and explore the capability of their application in neural networks.

For the capacitive coupling, two synchronization modes, with weak and strong coupling, are found. The transition between these modes is accompanied by chaotic oscillations.
