Melting upon cooling in a quantum magnet
K. JaksetiÄ, T. Arh, M. Pregelj +19
Heating enhances thermal fluctuations and typically leads to melting of solids, but in exceptional cases, heating can also cause liquids to solidify. The paradigm of this counterin…
Spin subdiffusion in perturbed infinite-U Hubbard chain
Jakub RÄkas, Marcin Mierzejewski, Zala LenarÄiÄ +1
The -model represents the Hubbard model in the limit and is one of the basic models of strongly correlated electrons. On a one-dimensional chain, the model is int…
Probing many-body localization crossover in quasiperiodic Floquet circuits on a quantum processor
Kazuma Nagao, Tomonori Shirakawa, Rongyang Sun +2
Many-body localization (MBL) provides a mechanism by which interacting quantum systems evade thermalization, leading to persistent memory of initial conditions and slow entanglemen…
Spin and energy diffusion vs. subdiffusion in disordered spin chains
J. Herbrych, P. Prelovšek
While the high-temperature spin diffusion in spin chains with random local fields has been the subject of numerous studies concerning the phenomenon of many-body localization (MBL)…
Easy-axis Heisenberg model on the triangular lattice: from supersolid to gapped solid
Martin Ulaga, Jure Kokalj, Takami Tohyama +1
We investigate the easy-axis Heisenberg model on the triangular lattice by numerically studying excitations and the dynamical spin structure factor . Results…
