Thermodynamics based on Neural Networks
D. Wagner, A. Klümper, J. Sirker
We present three different neural network algorithms to calculate thermodynamic properties as well as dynamic correlation functions at finite temperatures for quantum lattice model…
Topological Properties of Single-Particle States Decaying into a Continuum due to Interaction
B. Hawashin, J. Sirker, G. S. Uhrig
We investigate how topological Chern numbers can be defined when single-particle states hybridize with continua. We do so exemplarily in a bosonic Haldane model at zero temperature…
Symmetry-Resolved Entanglement: General considerations, calculation from correlation functions, and bounds for symmetry-protected topological phases
K. Monkman, J. Sirker
We discuss some general properties of the symmetry-resolved von-Neumann entanglement entropy in systems with particle number conservation and describe how to obtain the entanglemen…
Ising analogues of quantum spin chains with multispin interactions
Francisco C. Alcaraz, Rodrigo A. Pimenta, Jesko Sirker
A new family of free fermionic quantum spin chains with multispin interactions was recently introduced. Here we show that it is possible to build standard quantum Ising chains -- b…
