Symmetry-driven thermalization via finite de Finetti theorems
Uttam Singh, Nicolas J. Cerf
Thermal behavior in subsystems of closed quantum systems is commonly attributed to dynamical chaos, quantum ergodicity, canonical typicality, or the eigenstate thermalization hypot…

Sample Complexity of Black Box Work Extraction
Shantanav Chakraborty, Siddhartha Das, Arnab Ghorui +2
Extracting work from a physical system is one of the cornerstones of quantum thermodynamics. The extractable work, as quantified by ergotropy, necessitates a complete description o…
