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…

Exactly solvable models for universal operator growth
Oleksandr Gamayun, Murtaza Ali Mir, Oleg Lychkovskiy +1
Quantum observables of generic many-body systems exhibit a universal pattern of growth in the Krylov space of operators. This pattern becomes particularly manifest in the Lanczos b…
