Variational Minimization of Almost Strong Zero Modes in Parafermionic Wires
Niklas Tausendpfund, Matteo Rizzi
Strongly interacting fermionic chains obeying a symmetry can host topological phases with highly degenerate ground-state manifolds. The different ground states are connected…
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…
Quantum simulation of the tricritical Ising model in tunable Josephson junction ladders
Lorenzo Maffi, Niklas Tausendpfund, Matteo Rizzi +1
Modern hybrid superconductor-semiconductor Josephson junction arrays are a promising platform for analog quantum simulations. Their controllable and non-sinusoidal energy/phase rel…
Majorana Zero Modes in Fermionic Wires coupled by Aharonov-Bohm Cages
Niklas Tausendpfund, Sebastian Diehl, Matteo Rizzi
We devise a number-conserving scheme for the realization of Majorana Zero Modes in an interacting fermionic ladder coupled by Aharonov-Bohm cages. The latter provide an efficient m…
