thermodynamic restrictions. However, the quest for simpler methods to encompass all these …

Fundamental limits on anomalous energy flows in correlated quantum systems

P Lipka-Bartosik, GF Diotallevi, P Bakhshinezhad - Physical Review Letters, 2024 - APS
In classical thermodynamics energy always flows from the hotter system to the colder one.
However, if these systems are initially correlated, the energy flow can reverse, making the …
