Tree tensor networks for many-body localization in two dimensions
Lars Humpert, Dante M. Kennes, Jan-Niklas Herre
We investigate the disordered spin-Heisenberg model in two dimensions and employ tree tensor networks (TTNs) with a physics-informed structural optimization of the tree la…
Investigating Stark many-body localization with continuous unitary transformation flows
Jan-Niklas Herre, Qiyu Liu, Roman Rausch +2
We investigate the ergodicity-to-localization transition in interacting fermion systems subjected to a spatially uniform electric field. For that we employ the recently proposed Te…
Transport in Stark Many Body Localized Systems
Guy Zisling, Dante M. Kennes, Yevgeny Bar Lev
Using numerically exact methods we study transport in an interacting spin chain which for sufficiently strong spatially constant electric field is expected to experience Stark many…
Many-body localization and the area law in two dimensions
Kevin S. C. Decker, Dante M. Kennes, Christoph Karrasch
We study the high-energy phase diagram of a two-dimensional spin- Heisenberg model on a square lattice in the presence of either quenched or quasiperiodic disorder. Th…
Floquet engineering topological many-body localized systems
Kevin S. C. Decker, Christoph Karrasch, Jens Eisert +1
We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system. This allows…
Many-Body Localization in Two Dimensions from Projected Entangled-Pair States
D. M. Kennes
Using projected entangled-pair states (PEPS) we analyze the localization properties of two-dimensional systems on a square lattice. We compare the dynamics found for three differen…
