Quantum thermodynamics of the Caldeira-Leggett model with non-equilibrium Gaussian reservoirs
Vasco Cavina, Massimiliano Esposito
We introduce a non-equilibrium version of the Caldeira-Leggett model in which a quantum particle is strongly coupled to a set of engineered reservoirs. The reservoirs are composed…
Integrated covariances as excess observables weighted by currents and activities
Timur Aslyamov, Massimiliano Esposito
Near equilibrium, the symmetric part of the time-integrated steady-state covariance, i.e., the time integral of correlation functions, is governed by the fluctuation-dissipation th…
Synchronization of thermodynamically consistent stochastic phase oscillators
Maciej Chudak, Massimiliano Esposito, Krzysztof Ptaszynski
We consider a toy model of two kinetically coupled stochastic oscillators whose dynamics is described as a Markov jump process among discrete phase states. For large , it ma…
Classification of instabilities for the nonideal Brusselator model
Premashis Kumar, Massimiliano Esposito, Timur Aslyamov
We investigate a nonideal, thermodynamically consistent Brusselator reaction-diffusion (RD) system that explicitly incorporates molecular interactions among species in both the dif…
Nonequilibrium fluctuation-response relations for state observables
Krzysztof Ptaszynski, Timur Aslyamov, Massimiliano Esposito
Time-integrated state observables, which quantify the fraction of time spent by the system in a specific pool of states, are important in many fields, such as chemical sensing or t…
Nonequilibrium fluctuation-response relations for state-current correlations
Krzysztof Ptaszynski, Timur Aslyamov, Massimiliano Esposito
Recently, novel exact identities known as Fluctuation-Response Relations (FRRs) have been derived for nonequilibrium steady states of Markov jump processes. These identities link t…
