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…
Thermalization in Spatially Extended Open Quantum Systems: Local versus Global Markovian Evolution
Jorge Tabanera-Bravo, Massimiliano Esposito, Felipe Barra +1
We investigate the dynamics of a qubit chain locally coupled to a thermal reservoir, modeled through repeated collisions with particles drawn from a heat bath. Under suitable condi…
Quantum instanton theory for metastable collective spin systems
Krzysztof Ptaszynski, Maciej Chudak, Massimiliano Esposito
Collective spin systems -- driven-dissipative spin ensembles whose unitary and dissipative processes act uniformly on all spins, allowing their dynamics to be described as a single…
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…
Thermodynamics of coherent energy exchanges between lasers and two-level systems
Ariane Soret, Massimiliano Esposito
We study the quantum thermodynamics of a coherent macroscopic electromagnetic field (laser) coupled to a two-level system (qubit) near resonance, from weak to strong driving regime…
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…
Entropy-generated power and its efficiency
Natalia Golubeva, Alberto Imparato, Massimiliano Esposito
We propose a simple model for a motor that generates mechanical motion by exploiting an entropic force arising from the topology of the underlying phase space. We show that the gen…
