The Two Dimensional Dynamical Bulk Boundary Correspondence: Beyond Two Band Models
Tomasz Masłowski, 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…
On the Relation Between String Order Parameters, Entanglement, and Dynamical Quantum Phase Transitions in Topological Dynamics
Sirshendu Bhattacharyya, Szczepan Głodzik, 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 Głodzik, 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…
A Dynamical Bulk-Boundary Correspondence in Two Dimensional Topological Matter
Tomasz Masłowski, 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…
Fisher zeroes and dynamical quantum phase transitions for two- and three-dimensional models
Tomasz Masłowski, 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,…
The dynamical bulk boundary correspondence and dynamical quantum phase transitions in the Benalcazar-Bernevig-Hughes model
Tomasz Masłowski, Nicholas Sedlmayr
In this article we demonstrate that dynamical quantum phase transitions occur for an exemplary higher order topological insulator, the Benalcazar-Bernevig-Hughes model, following q…
Dynamical Phase Transitions in Topological Insulators
N. Sedlmayr
The traditional concept of phase transitions has, in recent years, been widened in a number of interesting ways. The concept of a topological phase transition separating phases wit…
The fate of dynamical phase transitions at finite temperatures and in open systems
N. Sedlmayr, M. Fleischhauer, J. Sirker
When a quantum system is quenched from its ground state, the time evolution can lead to non-analytic behavior in the return rate at critical times . Such dynamical phase trans…
Locality and thermalization in closed quantum systems
J. Sirker, N. P. Konstantinidis, F. Andraschko +1
We derive a necessary and sufficient condition for the thermalization of a local observable in a closed quantum system which offers an alternative explanation, independent of the e…
Transport and scattering in inhomogeneous quantum wires
N. Sedlmayr, J. Ohst, I. Affleck +2
We consider scattering and transport in interacting quantum wires that are connected to leads. Such a setup can be represented by a minimal model of interacting fermions with inhom…
Particle injection into a chain: decoherence versus relaxation for Hermitian and non-Hermitian dynamics
F. Gebhard, K. zu Muenster, J. Ren +3
We investigate a model system for the injection of fermionic particles from filled source sites into an empty chain. We study the ensuing dynamics for Hermitian as well as for non-…
