Coupling approach for the realization of a PT -symmetric potential for a Bose-Einstein condensate in a double well

- Fabian Single, H. Cartarius, G. Wunner, J. Main
- Physics
- 26 September 2014

We show how non-Hermitian potentials used to describe probability gain and loss in effective theories of open quantum systems can be achieved by a coupling of the system to an environment. We do this… Expand

Impact of the valence band structure of Cu$_{2}$O on excitonic spectra

- Frank Schweiner, J. Main, Matthias Feldmaier, G. Wunner, Christoph Uihlein
- Physics
- 2 April 2016

We present a method to calculate the exciton spectra of all direct semiconductors with a complex valence band structure. The Schr\"odinger equation is solved using a complete basis set with Coulomb… Expand

Dipolar Bose-Einstein condensates in a PT-symmetric double-well potential

- Rudiger Fortanier, Dennis Dast, +4 authors Robin Gutohrlein
- Physics
- 26 March 2014

We investigate dipolar Bose-Einstein condensates in a complex external double-well potential that features a combined parity and time-reversal symmetry. On the basis of the Gross-Pitaevskii equation… Expand

Obtaining time-dependent multi-dimensional dividing surfaces using Lagrangian descriptors

- Matthias Feldmaier, Andrej Junginger, J. Main, G. Wunner, R. Hernandez
- Physics
- 29 April 2017

Abstract Dynamics between reactants and products are often mediated by a rate-determining barrier and an associated dividing surface leading to the transition state theory rate. This framework is… Expand

Topological invariants in dissipative extensions of the Su-Schrieffer-Heeger model

- Felix Dangel, Marcel Wagner, H. Cartarius, J. Main, G. Wunner
- Physics, Mathematics
- 7 March 2018

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 describe the gain… Expand
