Measuring Anyonic Exchange Phases Using Two-Dimensional Coherent Spectroscopy
Nico Kirchner, Wonjune Choi, Frank Pollmann
Identifying experimental signatures of anyons, which exhibit fractional exchange statistics, remains a central challenge in the study of two-dimensional topologically ordered syste…
Spectral Functions of an Extended Antiferromagnetic Heisenberg Model on the Triangular Lattice
Markus Drescher, Laurens Vanderstraeten, Roderich Moessner +1
We study an extended spin- antiferromagnetic Heisenberg model on the triangular lattice, which includes both nearest- and next-nearest-neighbor interactions, as well as a scal…
Phases of Interacting Fibonacci Anyons on a Ladder at Half-Filling
Nico Kirchner, Roderich Moessner, Frank Pollmann +1
Two-dimensional many-body quantum systems can exhibit topological order and support collective excitations with anyonic statistics different from the usual fermionic or bosonic one…
Unconventional Spin Dynamics and Supersolid Excitations in the Triangular-Lattice XXZ Model
Rafael Flores-Calderón, Roderich Moessner, Frank Pollmann
Motivated by recent experiments, we investigate the spin-1/2 XXZ model on the triangular lattice with strong Ising anisotropy, combining large-scale numerical simulations and analy…
Localized Fock Space Cages in Kinetically Constrained Models
Cheryne Jonay, Frank Pollmann
We investigate a mechanism for non-ergodic behavior in many-body quantum systems arising from destructive interference, leading to localization in Fock space. Drawing parallels wit…
