Shaping the Branched Flow of Light through Disordered Media
Andre Brandstötter, Adrian Girschik, Philipp Ambichl +1
Electronic matter waves traveling through the weak and smoothly varying disorder potential of a semi-conductor show branching behavior instead of a smooth spreading of flow. By tra…
Dynamically encircling exceptional points in a waveguide: asymmetric mode switching from the breakdown of adiabaticity
Jörg Doppler, Alexei A. Mailybaev, Julian Böhm +7
Physical systems with loss or gain feature resonant modes that are decaying or growing exponentially with time. Whenever two such modes coalesce both in their resonant frequency an…
Percolating States in the Topological Anderson Insulator
Adrian Girschik, Florian Libisch, Stefan Rotter
We investigate the presence of percolating states in disordered two-dimensional topological insulators. In particular, we uncover a close connection between these states and the so…
The Single-Channel Regime of Transport through Random Media
A. Peña, A. Girschik, F. Libisch +2
The propagation of light through samples with random inhomogeneities can be described by way of transmission eigenchannels, which connect incoming and outgoing external propagating…
Topological Insulator in the Presence of Spatially Correlated Disorder
A. Girschik, F. Libisch, S. Rotter
We investigate the effect of spatially correlated disorder on two-dimensional topological insulators and on the quantum spin Hall effect which the helical edge states in these syst…
