Driven-Dissipative Bose-Einstein Condensation and the Upper Critical Dimension
Yikang Zhang, Thomas Barthel
Driving and dissipation can stabilize Bose-Einstein condensates. Using Keldysh field theory, we analyze this phenomenon for Markovian systems that can comprise on-site two-particle…

Criteria for Davies Irreducibility of Markovian Quantum Dynamics
Yikang Zhang, Thomas Barthel
The dynamics of Markovian open quantum systems are described by Lindblad master equations, generating a quantum dynamical semigroup. An important concept for such systems is (Davie…
