Numerical calculation of the complex berry phase in non-Hermitian systems
Marcel Wagner, Felix Dangel, Holger Cartarius +2
We numerically investigate topological phases of periodic lattice systems in tight-binding description under the influence of dissipation. The effects of dissipation are effectivel…

Photoabsorption spectra of the diamagnetic hydrogen atom in the transition regime to chaos: Closed orbit theory with bifurcating orbits
T. Fabcic, J. Main, T. Bartsch +1
With increasing energy the diamagnetic hydrogen atom undergoes a transition from regular to chaotic classical dynamics, and the closed orbits pass through various cascades of bifur…

Higher-order hbar corrections in the semiclassical quantization of chaotic billiards
K. Weibert, J. Main, G. Wunner
In the periodic orbit quantization of physical systems, usually only the leading-order hbar contribution to the density of states is considered. Therefore, by construction, the eig…
