Local correlations in long-range dual-unitary kicked Hamiltonian chains
Vladimir Al. Osipov, Marc Cedric Spyra, Jana Carolina Schumann +2
Many-body Floquet models with exact space--time symmetry, such as the kicked Ising spin chain (KIC), provide natural examples of systems with dual-unitary dynamics. The requirement…

Chern numbers in quantum graphs
Or Swartzberg, Omri Gat, Boris Gutkin
Quantum graphs provide an analytically tractable setting for the study of Chern numbers and band degeneracies in periodic systems. We study the Chern numbers of energy bands in a t…

The role of classical periodic orbits in quantum many-body systems
Daniel Waltner, Boris Gutkin
Semiclassical methods have been applied very successfully to describe the nontrivial transition from the quantum to the classical regime in -particle or at least $…
