Abstract: Abstract General nonequilibrium quantum transport equations are derived for a coupled system of charge carriers, Dirac spin, isospin (or valley spin), and pseudospin, such as either one of the band, layer, impurity, and boundary pseudospins.… read more here.

Abstract: By nonperturbatively solving the nonequilibrium Anderson two-impurity model with the hierarchical equations of motion approach, we report a robust ferromagnetic (FM) phase in series-coupled double quantum dots, which can suppress the antiferromagnetic (AFM) phase and… read more here.

Abstract: An accelerated detector will see thermal radiation around with temperature T which is termed as Unruh effect. The two accelerated observers can detect quantum correlations between them through the vacuum field. A natural question arises:… read more here.

DOI: 10.1103/physrevlett.120.063605
Abstract: We consider a hybrid quantum many-body system formed by a vibrational mode of a nanomembrane, which interacts optomechanically with light in a cavity, and an ultracold atom gas in the optical lattice of the out-coupled… read more here.
