Gauge-covariant projected entangled paired states for interacting systems in a magnetic field
Wei Tang, Gunnar Möller, Frank Verstraete +1
The Hamiltonian for a system of itinerant particles on a two-dimensional lattice in a uniform magnetic field reduces the translational symmetry to a magnetic translation group, bec…
Fidelity and quantum geometry approach to Dirac exceptional points in diamond nitrogen-vacancy centers
Chia-Yi Ju, Gunnar Möller, Yu-Chin Tzeng
Dirac exceptional points (EPs) represent a novel class of non-Hermitian singularities that, unlike conventional EPs, reside entirely within the parity-time unbroken phase and exhib…
Dissociation of bulk and entanglement phase transitions in the Haldane phase
Yu-Chin Tzeng, Gunnar Möller
Quantum entanglement provides a sensitive probe of topological phases and strong correlations in quantum many-body systems. We revisit the momentum-resolved entanglement spectrum (…
Fitness landscape for quantum state tomography from neutron scattering
Tymoteusz Tula, Jorge Quintanilla, Gunnar Möller
Recently, a direct connection between static structure factors and quantum ground states for two-spin interaction Hamiltonians was proven. This suggests the possibility of quantum…
Tensor Network Python (TeNPy) version 1
Johannes Hauschild, Jakob Unfried, Sajant Anand +27
TeNPy (short for 'Tensor Network Python') is a python library for the simulation of strongly correlated quantum systems with tensor networks. The philosophy of this library is to a…
Topological Phase Transitions in the Disordered Haldane Model
J. Mildner, M. D. Caio, G. Möller +2
We investigate the phases and phase transitions of the disordered Haldane model in the presence of on-site disorder. We use the real-space Chern marker and transfer matrices to ext…
