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 $…
Local correlations in partially dual-unitary lattice models
Vladimir Al. Osipov, Niclas Krieger, Thomas Guhr +1
We consider the problem of local correlations in the kicked, dual-unitary coupled maps on D-dimensional lattices. We demonstrate that for D>=2, fully dual-unitary systems exhibit u…
Particle-Time Duality in the Kicked Ising Chain II: Applications to the Spectrum
M. Akila, D. Waltner, B. Gutkin +1
Previously, we demonstrated that the dynamics of kicked spin chains possess a remarkable duality property. The trace of the unitary evolution operator for spins at time is…
Universality in spectral statistics of "open" quantum graphs
Boris Gutkin, Vladimir Al. Osipov
The unitary evolution maps in closed chaotic quantum graphs are known to have universal spectral correlations, as predicted by random matrix theory. In chaotic graphs with absorpti…
Collective versus Single--Particle Motion in Quantum Many--Body Systems: Spreading and its Semiclassical Interpretation
Jens Hammerling, Boris Gutkin, Thomas Guhr
We study the interplay between collective and incoherent single-particle motion in a model of two chains of particles whose interaction comprises a non-integrable part. In the pert…
