Mean path length invariance in wave-scattering beyond the diffusive regime
Matthieu Davy, Matthias Kühmayer, Sylvain Gigan +1
Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the d…
Customizing the angular memory effect for scattering media
Hasan Yılmaz, Matthias Kühmayer, Chia Wei Hsu +2
The memory effect in disordered systems is a key physical phenomenon that has been employed for optical imaging, metrology, and communication through opaque media. Under the conven…
Shape-preserving beam transmission through non-Hermitian disordered lattices
A. F. Tzortzakakis, K. G. Makris, S. Rotter +1
We investigate the propagation of Gaussian beams through optical waveguide lattices characterized by correlated non-Hermitian disorder. In the framework of coupled mode theory, we…
Encircling exceptional points as a non-Hermitian extension of rapid adiabatic passage
Juraj Feilhauer, Alexander Schumer, Jörg Doppler +5
The efficient transfer of excitations between different levels of a quantum system is a task with many applications. Among the various protocols to carry out such a state transfer…
Emergence of PT-symmetry breaking in open quantum systems
Julian Huber, Peter Kirton, Stefan Rotter +1
The effect of PT-symmetry breaking in coupled systems with balanced gain and loss has recently attracted considerable attention and has been demonstrated in various photonic, elect…
