Universal bound on the Lyapunov spectrum of quantum master equations
Paolo Muratore-Ginanneschi, Gen Kimura, Frederik vom Ende +1
The spectral properties of positive maps are pivotal for understanding the dynamics of quantum systems interacting with their environment. Furthermore, central problems in quantum…
Decay of the survival probability of a local excitation in multi-qubit platforms
Paolo Muratore-Ginanneschi, Bayan Karimi, Jukka Pekola
We present a theoretical study of the survival probability of a state initially prepared in the one-particle sector of a multi-qubit system. The motivation for our work is the ongo…
Thermalization in high-dimensional systems: the (weak) role of chaos
Marco Baldovin, Marco Cattaneo, Dario Lucente +2
In their seminal work, Fermi, Pasta, Ulam and Tsingou explored the connection between statistical mechanics and dynamical properties, such as chaos and ergodicity. Even today, seve…
What is a minimum work transition in stochastic thermodynamics?
Paolo Muratore-Ginanneschi, Julia Sanders
We reassess the concept of transition at minimum work in classical stochastic finite-time thermodynamics, when the system dynamics is modelled by a diffusion process. We show that…
Heat flow through the quantum heat valve coupled to ohmic baths via a master equation approach
Antti Vaaranta, Marco Cattaneo, Paolo Muratore-Ginanneschi +1
We provide a theoretical model for the non-equilibrium steady state heat flow through a quantum heat valve. The model is based on a master equation approach, where the partial secu…
Classical uncertainty relations and entropy production in non-equilibrium statistical mechanics
Paolo Muratore-Ginanneschi, Luca Peliti
We analyze Fürth's 1933 classical uncertainty relations in the modern language of stochastic differential equations. Our interest is motivated by applications to non-equilibrium c…
