Thermodynamic perspective on quantum fluctuations

A Sone, K Sinha, S Deffner - arxiv preprint arxiv:2308.04951, 2023 - arxiv.org
What is the major difference between large and small systems? At small length-scales the
dynamics is dominated by fluctuations, whereas at large scales fluctuations are irrelevant …

Quantum work statistics across a critical point: full crossover from sudden quench to the adiabatic limit

Z Ma, AK Mitchell, E Sela - arxiv preprint arxiv:2502.01601, 2025 - arxiv.org
When an external parameter drives a system across a quantum phase transition at a finite
rate, work is performed on the system and entropy is dissipated, due to the creation of …
