Game of Nons: Non-Gaussian Nonunitary Environments with Nonlinear Coupling
Artem Karasev, Alexander Teretenkov
We develop a perturbative framework for systems coupled quadratically to bosonic environments with quadratic Hamiltonians and linear Lindblad operators. The method applies to both…
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…
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…
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…
