Dissipative dynamics of circuit-QED in the mesoscopic regime [PDF]
, 2007 We investigate the behavior of a circuit QED device when the resonator is initially populated with a mesoscopic coherent field. The strong coupling between the cavity and the qubit produces an entangled state involving mesoscopic quasi-pointer states ...

Design of a Fast Digital Double Relaxation Oscillation SQUID [PDF]
, 2001 A fast digital Double Relaxation Oscillation SQUID (DROS) with a relaxation oscillation frequency of 100 MHz has been developed. The digital DROS incorporates a DROS and a superconducting up-down counter that supplies the feedback flux.

Nonuniform gyrotropic oscillation of skyrmion in a nanodisk
AIP Advances, 2018 It was predicted that magnetic skyrmions have potential application in the spin nano-oscillators. The oscillation frequency is a key parameter. In this paper, we study the skyrmion relaxation in a FeGe nanodisk and find that the oscillation frequency ...

A neural network approach for composite fractional relaxation oscillation equations in complex dynamical systems [PDF]
AIP AdvancesThe relaxation oscillator is a system that operates on the tendency of physical processes to return to equilibrium after being disturbed. Its governing equation, the relaxation–oscillation equation, plays a central role in diverse fields such as physics,
