Evolution speed of open quantum dynamics

HIGHLIGHTS

• who: Dorje C. Brody from the DepartmentUniversity of Surrey, Guildford , XH, United Kingdom have published the article: Evolution speed of open quantum dynamics, in the Journal: (JOURNAL) of 25/Nov/2019
• what: For a PT-symmetric quantum system, the authors show that the existence of a phase transition leads to qualitatively different behaviors of the speed; while in a Bose-Hubbard system coupled to a reservoir the authors show that the evolution speed need not be decreasing in time, contrary to what other studies have suggested. is a family of Lindblad operators characterising the system . . .
