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…
