Observation of supersymmetric pseudo-Landau levels in strained microwave graphene
Matthieu Bellec, Charles Poli, Ulrich Kuhl +2
Using an array of coupled microwave resonators arranged in a deformed honeycomb lattice, we experimentally observe the formation of pseudo-Landau levels in the whole crossover from…
Cross section versus time delay and trapping probability
G. A. Luna-Acosta, A. A. Fernández-Marín, J. A. Méndez-Bermúdez +1
We study the behavior of the -wave partial cross section , the Wigner-Smith time delay , and the trapping probability as function of the wave number . The…
Partial chiral symmetry-breaking as a route to spectrally isolated topological defect states in two-dimensional artificial materials
Charles Poli, Henning Schomerus, Matthieu Bellec +2
Bipartite quantum systems from the chiral universality classes admit topologically protected zero modes at point defects. However, in two-dimensional systems these states can be di…
Universal sign-control of coupling in tight-binding lattices
Robert Keil, Charles Poli, Matthias Heinrich +4
We present a method of locally inverting the sign of the coupling term in tight-binding systems, by means of inserting a judiciously designed ancillary site and eigenmode matching…
Topologically protected defect states in open photonic systems with non-hermitian charge-conjugation and parity-time symmetry
Simon Malzard, Charles Poli, Henning Schomerus
We show that topologically protected defect states can exist in open (leaky or lossy) systems even when these systems are topologically trivial in the closed limit. The states appe…
Influence of the Coulomb potential on above-threshold ionization: a quantum-orbit analysis beyond the strong-field approximation
X. -Y. Lai, C. Poli, H. Schomerus +1
We perform a detailed analysis of how the interplay between the residual binding potential and a strong laser field influences above-threshold ionization (ATI), employing a semi-an…
