Open-system eigenstate thermalization in a noninteracting integrable model
Krzysztof Ptaszynski, Massimiliano Esposito
Significant attention has been devoted to the problem of thermalization of observables in isolated quantum setups by individual eigenstates. Here, we address this issue from an ope…

Dynamical signatures of discontinuous phase transitions: How phase coexistence determines exponential versus power-law scaling
Krzysztof Ptaszynski, Massimiliano Esposito
There are conflicting reports in the literature regarding the finite-size scaling of the Liouvillian gap and dynamical fluctuations at discontinuous phase transitions, with various…

Dissipation bounds precision of current response to kinetic perturbations
Krzysztof Ptaszynski, Timur Aslyamov, Massimiliano Esposito
The precision of currents in Markov networks is bounded by dissipation via the so-called thermodynamic uncertainty relation (TUR). In our work, we demonstrate a similar inequality…
