Three-dimensional photonic topological insulator induced by lattice dislocations
Eran Lustig, Lukas J. Maczewsky, Julius Beck +6
The hallmark of topological insulators is the scatter-free propagation of waves in topologically protected edge channels. This transport is strictly chiral on the outer edge of the…
Experimental realisation of -symmetric flat bands
Tobias Biesenthal, Mark Kremer, Matthias Heinrich +1
The capability to temporarily arrest the propagation of optical signals is one of the main challenges hampering the ever more widespread use of light in rapid long-distance transmi…
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…
