Time evolution of the quantum Ising model in two dimensions using Tree Tensor Networks
Wladislaw Krinitsin, Niklas Tausendpfund, Markus Heyl +2
The numerical simulation of two-dimensional quantum many-body systems away from equilibrium constitutes a major challenge for all known computational methods. We investigate the ut…
Triangular lattice models of the Kalmeyer-Laughlin spin liquid from coupled wires
Tingyu Gao, Niklas Tausendpfund, Erik L. Weerda +3
Chiral spin liquids (CSLs) are exotic phases of interacting spins in two dimensions, characterized by long-range entanglement and fractional excitations. We construct a local Hamil…
Almost Strong Zero Modes at Finite Temperature
Niklas Tausendpfund, Aditi Mitra, Matteo Rizzi
Interacting fermionic chains exhibit extended regions of topological degeneracy of their ground states as a result of the presence of Majorana or parafermionic zero modes localized…
Roughening dynamics of interfaces in the two-dimensional quantum Ising model
Wladislaw Krinitsin, Niklas Tausendpfund, Matteo Rizzi +2
The properties of interfaces are key to understand the physics of matter. However, the study of quantum interface dynamics has remained an outstanding challenge. Here, we use large…
