The Two Dimensional Dynamical Bulk Boundary Correspondence: Beyond Two Band Models
Tomasz MasÅowski, Nicholas Sedlmayr
A dynamical equivalent of the bulk-boundary correspondence has been suggested to occur in one and two dimensional topological models following sudden quenches. Depending on the top…
A Dynamical Bulk-Boundary Correspondence in Two Dimensional Topological Matter
Tomasz MasÅowski, Jesko Sirker, Nicholas Sedlmayr
We provide strong numerical evidence for a dynamical bulk-boundary correspondence in two-dimensional topological matter which manifests itself as boundary contributions to the dyna…
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…
Torsion Induced Asymmetric Luttinger Liquids
Arseny Pantsialei, Nicholas Sedlmayr
We consider a general model of a Luttinger liquid with broken parity and time reversal symmetry, but with their composite symmetry intact. Such a scenario can be due to a combinati…
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…
Fisher zeroes and dynamical quantum phase transitions for two- and three-dimensional models
Tomasz MasÅowski, Hadi Cheraghi, Jesko Sirker +1
Dynamical quantum phase transitions are non-analyticities in a dynamical free energy (or return rate) which occur at critical times. Although extensively studied in one dimension,…
