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…
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…
