Krylov Tomography and Finite-Uncertainty Certification of Exceptional-Point Dynamics
Aritra Ghosh, M. Bhattacharya
Exceptional points (EPs) can produce striking responses, but locating one does not reveal how much of its dynamics an excitation accesses, which responses a detector distinguishes,…

Quantum jumps in open cavity optomechanics and Liouvillian versus Hamiltonian exceptional points
Aritra Ghosh, M. Bhattacharya
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 dynamic…
