Efficient excitation-transfer across fully connected networks via local-energy optimization
S. Sgroi, G. Zicari, A. Imparato +1
We study the excitation transfer across a fully connected quantum network whose sites energies can be artificially designed. Starting from a simplified model of a broadly-studied p…

Energy conservation and fluctuation theorem are incompatible for quantum work
Karen V. Hovhannisyan, Alberto Imparato
Characterizing fluctuations of work in coherent quantum systems is notoriously problematic. Here we reveal the ultimate source of the problem by proving that () energ…
