Periodic orbits and quantum many-body scars in integrable spin chains
Elena Petrova, Maksym Serbyn, Marko Ljubotina
The paper applies periodic‑orbit theory to integrable XYZ/XXZ spin‑1/2 chains, identifying families of scarred periodic orbits and reconstructing the associated non‑thermal eigenst…

Finding periodic orbits in projected quantum many-body dynamics
Elena Petrova, Marko Ljubotina, Gökhan Yalnız +1
Describing general quantum many-body dynamics is a challenging task due to the exponential growth of the Hilbert space with system size. The time-dependent variational principle (T…
