Fermionic time-reversal symmetry in a photonic topological insulator
Lukas J. Maczewsky, Bastian Höckendorf, Mark Kremer +5
Much of the recent enthusiasm directed towards topological insulators as a new state of matter is motivated by their hallmark feature of protected chiral edge states. In fermionic…
Demonstration of a two-dimensional PT-symmetric crystal: Bulk dynamics, topology, and edge states
Mark Kremer, Tobias Biesenthal, Matthias Heinrich +2
In 1998, Carl Bender challenged the perceived wisdom of quantum mechanics that the Hamiltonian operator describing any quantum mechanical system has to be Hermitian. He showed that…
Observation of Light Guiding by Artificial Gauge Fields
Yaakov Lumer, Miguel A. Bandres, Matthias Heinrich +4
The use of artificial gauge fields enables systems of uncharged particles to behave as if affected by external fields. Generated by geometry or external modulation, artificial gaug…
