Physikalisches Kolloquium am 04.07.2022: Topology – Open and with Diverse Backgrounds

28.06.22 | Veranstaltung

Am Montag (04.07.22) um 12.00 Uhr c.t. findet der nächste Termin unseres Physikalischen Kolloquiums statt.

Referent ist Dr. Tobias Meng (TU Dresden) zum Thema:

„Topology – Open and with Diverse Backgrounds“.

The advent of topological physics has been a major disruption in the way we think about condensed matter physics. In its most basic form, topological physics relies on the definition of topological invariants defined from the wave functions in the Brillouin zone, including for example the Chern number governing the Hall effect. Implicitly, this view of topological physics requires closed systems with translation invariance.
In this talk, I will show that the fact that any experimental system is open (coupled to its environment) and never fully translationally invariant can be a resource rather than a nuisance. When suitable couplings to environments and inhomogeneities are induced, topological systems exhibit a plethora of novel phenomena, including black hole analogies and non-trivial steady states. This highlights that the study of topological systems out of the ”comfort zone” (closed and translationally invariant) is a worthwhile direction for future research.
