Coherence susceptibility as a probe of quantum phase transitions
Jin-Jun Chen, Jian Cui, Yu-Ran Zhang +1
We introduce a coherence susceptibility method, based on the fact that it signals quantum fluctuations, for identifying quantum phase transitions, which are induced by quantum fluc…

Variational Matrix Product Operators for the Steady State of Dissipative Quantum Systems
Jian Cui, J. Ignacio Cirac, Mari Carmen Bañuls
We present a new variational method, based on the matrix product operator (MPO) ansatz, for finding the steady state of dissipative quantum chains governed by master equations of t…
