On the Relation Between String Order Parameters, Entanglement, and Dynamical Quantum Phase Transitions in Topological Dynamics
Sirshendu Bhattacharyya, Szczepan GÅodzik, Nicholas Sedlmayr
Topological order is defined by topological invariants, rather than symmetries and local order parameters. Nonetheless some topological phases can be characterized by string order…

Dynamical Scarring from Scrambling in Two Dimensional Topological Materials
Dominik Szpara, Szczepan GÅodzik, Nicholas Sedlmayr
Out-of-time ordered correlators are a probe of how the information of an initial perturbation is effectively scrambled under unitary time evolution, widely used to study quantum ch…

Entanglement entropy scaling laws from fluctuations of non-conserved quantities
Szczepan GÅodzik, Kim Pöyhönen, Ali G. Moghaddam +1
Entanglement patterns reveal essential information on many-body states and provide a way to classify quantum phases of matter. However, experimental studies of many-body entangleme…
