Dissipation and fluctuations of CMOS ring oscillators close to criticality
Ashwin Gopal, Massimiliano Esposito, Jan Meibohm
We analyze a thermodynamically consistent model of CMOS-based ring oscillators near the onset of coherent voltage oscillations. For driving voltages close to the critical value, we…
Critical Fluctuations at Finite-Time Dynamical Phase Transition
Nalina Vadakkayil, Massimiliano Esposito, Jan Meibohm
We explore the critical properties of the recently discovered finite-time dynamical phase transition in the non-equilibrium relaxation of Ising magnets after a temperature quench.…
Exponential Change of Relaxation Rate by Quenched Disorder
Jan Meibohm, Sabine H. L. Klapp
We determine the asymptotic relaxation rate of a Brownian particle in a harmonic potential perturbed by quenched Gaussian disorder, a simplified model for rugged energy landscapes…
Minimum-dissipation principle for synchronised stochastic oscillators far from equilibrium
Jan Meibohm, Massimiliano Esposito
We prove a linear stability-dissipation relation (SDR) for -state Potts models driven far from equilibrium by a nonconservative force. At a critical coupling strength, these mod…
Small-amplitude synchronisation in driven Potts models
Jan Meibohm, Massimiliano Esposito
We study driven -state Potts models with thermodynamically consistent dynamics and global coupling. For a wide range of parameters, these models exhibit a dynamical phase transi…
