Quantum Dynamics with Stochastic Non-Hermitian Hamiltonians
Pablo Martinez-Azcona, Aritra Kundu, Avadh Saxena +2
We study the quantum dynamics generated by a non-Hermitian Hamiltonian subject to stochastic perturbations in its anti-Hermitian part, describing fluctuating gains and losses. The…

A geometrical description of non-Hermitian dynamics: speed limits in finite rank density operators
Niklas Hörnedal, Oskar A. Prośniak, Adolfo del Campo +1
Non-Hermitian dynamics in quantum systems preserves the rank of the state density operator. Using this insight, we develop a geometric framework to describe its time evolution. In…
