Chain-mapping methods for relativistic light-matter interactions
Robert H. Jonsson, Johannes Knörzer
The interaction between localized emitters and quantum fields, both in relativistic settings and in the case of ultra-strong couplings, requires non-perturbative methods beyond the…
Spin-Holstein models in trapped-ion systems
Johannes Knörzer, Tao Shi, Eugene Demler +1
In this work, we highlight how trapped-ion quantum systems can be used to study generalized Holstein models, and benchmark expensive numerical calculations. We study a particular s…
Excitonic Tonks-Girardeau and charge-density wave phases in monolayer semiconductors
Rafał Ołdziejewski, Alessio Chiocchetta, Johannes Knörzer +1
Excitons in two-dimensional semiconductors provide a novel platform for fundamental studies of many-body interactions. In particular, dipolar interactions between spatially indirec…
Highly excited electronic image states of metallic nanorings
Christian Fey, Henrik Jabusch, Johannes Knörzer +1
We study electronic image states around a metallic nanoring and show that the interplay between the attractive polarization force and a repulsive centrifugal force gives rise to Ry…
Control of multiple excited image states around segmented carbon nanotubes
J. Knörzer, C. Fey, H. R. Sadeghpour +1
Electronic image states around segmented carbon nanotubes can be confined and shaped along the nanotube axis by engineering the image potential. We show how several such image stat…
Correlated Quantum Dynamics of a Single Atom Collisionally Coupled to an Ultracold Finite Bosonic Ensemble
Sven Krönke, Johannes Knörzer, Peter Schmelcher
We explore the correlated quantum dynamics of a single atom, regarded as an open system, with a spatio-temporally localized coupling to a finite bosonic environment. The single ato…
Nonequilibrium Landau-Zener-Stuckelberg spectroscopy in a double quantum dot
P. Nalbach, J. Knorzer, S. Ludwig
We study theoretically nonequilibrium Landau-Zener-Stückelberg (LZS) dynamics in a driven double quantum dot (DQD) including dephasing and, importantly, energy relaxation due to en…
