Dynamical phase transitions for single particles in the semiclassical and weak noise limits
Norayr Asriyan, Jan Meibohm, Vasco Cavina +1
We present a unifying description of dynamical phase transitions in the unitary evolution of an isolated quantum particle and the dissipative relaxation of a classical Brownian par…
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…
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…
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.…
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…
Landau theory for finite-time dynamical phase transitions
Jan Meibohm, Massimiliano Esposito
We study the time evolution of thermodynamic observables that characterise the dissipative nature of thermal relaxation after an instantaneous temperature quench. Combining tools f…
Finite-time dynamical phase transition in non-equilibrium relaxation
Jan Meibohm, Massimiliano Esposito
We uncover a finite-time dynamical phase transition in the thermal relaxation of a mean-field magnetic model. The phase transition manifests itself as a cusp singularity in the pro…
Relaxation-speed crossover in anharmonic potentials
Jan Meibohm, Danilo Forastiere, Tunrayo Adeleke-Larodo +1
In a recent Letter [A. Lapolla and A. Godec, Phys. Rev. Lett. 125, 110602 (2020)], thermal relaxation was observed to occur faster from cold to hot (heating) than from hot to cold…
Paths to caustic formation in turbulent aerosols
Jan Meibohm, Vikash Pandey, Akshay Bhatnagar +4
The dynamics of small, yet heavy, identical particles in turbulence exhibits singularities, called caustics, that lead to large fluctuations in the spatial particle-number density,…
