Quantum and classical contributions to entropy production in fermionic and bosonic gaussian systems
K Ptaszyński, M Esposito - PRX Quantum, 2023 - APS
As previously demonstrated, the entropy production—a key quantity characterizing the
irreversibility of thermodynamic processes—is related to generation of correlations between …

Work Statistics and Entanglement Across the Fermionic Superfluid‐Insulator Transition
Entanglement in many‐body systems may display quantum phase transition signatures, and
analogous insights are emerging in the study of work fluctuations. Here, the fermionic …

Work statistics and symmetry breaking in an excited-state quantum phase transition
We examine how the presence of an excited-state quantum phase transition manifests in the
dynamics of a many-body system subject to a sudden quench. Focusing on the Lipkin …

Entropy production dynamics in quench protocols of a driven-dissipative critical system
Driven-dissipative phase transitions are currently a topic of intense research due to the
prospect of experimental realizations in quantum optical setups. The most paradigmatic …

Measuring energy by measuring any other observable
D Šafránek, D Rosa - Physical Review A, 2023 - APS
We present a method to estimate the probabilities of outcomes of a quantum observable, its
mean value, and higher moments by measuring any other observable. This method is …
