Absence of dissipation-free topological edge states in quadratic open fermions
Liang Mao
We prove a no-go theorem: generic quadratic open fermionic systems governed by Lindblad master equations do not host dissipation-free topological edge states protected by the dissi…

Symmetry classification correspondence between quadratic Lindbladians and their steady states
Liang Mao, Fan Yang
Symmetry classification is crucial in understanding universal properties of quantum matter. Recently, the scope of symmetry classification has been extended to open quantum systems…

Probing the Topology of Fermionic Gaussian Mixed States with {U(1)} symmetry by Full Counting Statistics
Liang Mao, Hui Zhai, Fan Yang
Topological band theory has been studied for free fermions for decades, and one of the most profound physical results is the bulk-boundary correspondence. Recently a focus in topol…
