Quantum jumps in open cavity optomechanics and Liouvillian versus Hamiltonian exceptional points (opens in new tab)

arXiv:2602.22205v1 Announce Type: new Abstract: Exceptional points, where two or more eigenstates of a non-Hermitian system coalesce, are now of interest across many fields of physics, from the perspective of open-system dynamics, sensing, nonreciprocal transport, and topological phase transitions. In this work, we investigate exceptional points in cavity optomechanics, a platform of interest to diverse communities working on gravitational-wave detection, macroscopic quantum mechanics, quant...
