Learning Hidden Structures in Open Quantum Dynamics
Alexander Teretenkov, Sergey Kuznetsov, Alexander Pechen
We introduce a machine-learning approach for identifying hidden structural features of open quantum dynamics under restricted experimental access. Unlike most existing data-driven…

Duality between open systems and closed bilayer systems: Thermofield double states as quantum many-body scars
Alexander Teretenkov, Oleg Lychkovskiy
We establish a duality between open many-body systems governed by the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equation and satisfying the detailed balance condition on the one…

Pseudomode expansion of many-body correlation functions
Alexander Teretenkov, Filipp Uskov, Oleg Lychkovskiy
We present an expansion of a many-body correlation function in a sum of pseudomodes -- exponents with complex frequencies that encompass both decay and oscillations. The pseudomode…
