Hybrid-Liouvillian formalism connecting exceptional points of non-Hermitian Hamiltonians and Liouvillians via postselection of quantum trajectories
to the spectra of Liouvillian superoperators governing open system dynamics described. We discuss these connections by introducing a hybrid-Liouvillian superoperator trajectories without quantum jumps) to a true Liouvillian

Quantum Liouvillian exceptional and diabolical points for bosonic fields with quadratic Hamiltonians: The Heisenberg-Langevin equation approach
Equivalent approaches to determine eigenfrequencies of the Liouvillians of open quantum systems are discussed using the solution of the Heisenberg-Langevin equations and the corresponding equations for operator moments. A simple damped two-l...

Quantum and semiclassical exceptional points of a linear system of coupled cavities with losses and gain within the Scully-Lamb laser theory
one to determine quantum EPs from a Liouvillian EP (LEP), rather than from an NHH, has been proposed. Compared to the NHHs, a Liouvillian naturally includes quantum, based on an NHH and a Liouvillian within the Scully-Lamb...

Generating high-order quantum exceptional points in synthetic dimensions
, by considering the full quantum dynamics of a quadratic Liouvillian superoperator, we allows correct reproduction of the results of the Liouvillian dynamics, including quantum jumps. As an example, we consider a U(1)-symmetric qua...
