Harnessing nonadiabatic excitations promoted by a quantum critical point: Quantum battery and spin squeezing

2022-09-19T15:57:05+02:00Tags: , |

Authors: Abah, Obinna; De Chiara, Gabriele; Paternostro, Mauro; Puebla, Ricardo Journal: PHYSICAL REVIEW RESEARCH Publication date: 2022/04/22 DOI: 10.1103/PhysRevResearch.4.L022017 Abstract: Crossing a quantum critical point in finite time challenges the adiabatic condition due to the closing of the energy gap, which ultimately results in the formation of excitations. Such nonadiabatic excitations are typically deemed detrimental [...]
