Superconductivity, superfluidity and quantum geometry in twisted multilayer systems

P Törmä, S Peotta, BA Bernevig - Nature Reviews Physics, 2022 - nature.com
Superconductivity has been observed in moiré systems such as twisted bilayer graphene,
which host flat, dispersionless electronic bands. In parallel, theory work has discovered that …

Quantum phase with coexisting localized, extended, and critical zones

Y Wang, L Zhang, W Sun, TFJ Poon, XJ Liu - Physical Review B, 2022 - APS
Conventionally a mobility edge (ME) marks a critical energy that separates two different
transport zones where all states are extended and localized, respectively. Here we propose …

Stochastic thermodynamics of rapidly driven systems

GB Cuetara, A Engel, M Esposito - New journal of physics, 2015 - iopscience.iop.org
We present the stochastic thermodynamics analysis of an open quantum system weakly
coupled to multiple reservoirs and driven by a rapidly oscillating external field. The analysis …
