Hybrid Breathers in Nonlinear -Symmetric Metamaterials
Sascha Böhrkircher, Sebastian Erfort, Holger Cartarius +1
On a two-dimensional planar parity-time-(-)symmetric nonlinear magnetic metamaterial, consisting of split-ring dimers with balanced gain and loss, discrete breather s…
Topological invariants in dissipative extensions of the Su-Schrieffer-Heeger model
Felix Dangel, Marcel Wagner, Holger Cartarius +2
We investigate dissipative extensions of the Su-Schrieffer-Heeger model with regard to different approaches of modeling dissipation. In doing so, we use two distinct frameworks to…
Population transfer at exceptional points in spectra of the hydrogen atom in parallel electric and magnetic fields
Lukas Oberreiter, Jan Burkhardt, Jörg Main +1
We study the population transfer between resonance states for a time-dependent loop around exceptional points in spectra of the hydrogen atom in parallel electric and magnetic fiel…
Using mixed many-body particle states to generate exact -symmetry in a time-dependent four-well system
Tina Mathea, Dennis Dast, Daniel Dizdarevic +3
Bose-Einstein condensates with balanced gain and loss in a double-well potential have been shown to exhibit PT-symmetric states. As proposed by Kreibich et al [Phys. Rev. A 87, 051…
Neural network approach to time-dependent dividing surfaces in classical reaction dynamics
Philippe Schraft, Andrej Junginger, Matthias Feldmaier +4
In a dynamical system, the transition between reactants and products is typically mediated by an energy barrier whose properties determine the corresponding pathways and rates. The…
Crossover between the Gaussian orthogonal ensemble, the Gaussian unitary ensemble, and Poissonian statistics
Frank Schweiner, Jeanine Laturner, Jörg Main +1
Until now only for specific crossovers between Poissonian statistics (P), the statistics of a Gaussian orthogonal ensemble (GOE), or the statistics of a Gaussian unitary ensemble (…
