Racetrack computing with a topological boundary ratchet
Parisa Omidvar, Markus Bestler, Sima Zahedi Fard +2
Multistable order parameters provide a natural means of encoding non-volatile information in spatial domains, a concept that forms the foundation of magnetic memory devices. Howeve…
Quantized nonlinear kink movement through topological boundary state instabilities
Markus Bestler, Oded Zilberberg
Thouless pumping is a paradigmatic example of topologically protected, directed transport in linear systems. Recent extensions to nonlinear pumps often overlook the need to reasses…
Ultrafast Non-Hermitian Skin Effect
Barbara Schneider, Alexander Dikopoltsev, Markus Bestler +5
Topological phases of matter commonly feature protected states at their boundaries. Transferring this protection to time-metamaterials is extremely challenging, as it requires the…
Non-Hermitian topology and skin modes in the continuum via parametric processes
Markus Bestler, Alexander Dikopoltsev, Oded Zilberberg
We demonstrate that Hermitian, nonlocal parametric pairing processes can induce non-Hermitian topology and skin modes, offering a simple alternative to complex bath engineering. Ou…
