Van der Waals interaction potential between Rydberg atoms near surfaces
Johannes Block, Stefan Scheel
Van der Waals interactions, as a result of the exchange of photons between particles, can be altered by modifying the environment through which these photons propagate. As a conseq…
Waveguides for Rydberg excitons in CuO from strain traps
Sjard Ole Krüger, Stefan Scheel
We investigate the formation of waveguides for Rydberg excitons in CuO from cylindrical stressors as alternatives to optical traps. We show that the achievable potential…
Angular-Momentum Couplings in Ultra-Long-Range Giant Dipole Molecules
Thomas Stielow, Stefan Scheel, Markus Kurz
In this article we extend the theory of ultra-long-range giant dipole molecules, formed by an atom in a giant dipole state and a ground-state alkali atom, by angular-momentum coupl…
Radiative heat transfer between spatially nonlocally responding dielectric objects
Robin Schmidt, Stefan Scheel
We calculate numerically the heat transfer rate between a spatially dispersive sphere and a half-space. By utilising Huygens' principle and the extinction theorem, we derive the ne…
A Green's function approach to giant-dipole systems
Thomas Stielow, Stefan Scheel, Markus Kurz
In this work we perform a Green's function analysis of giant-dipole systems. First we derive the Green's functions of different magnetically field-dressed systems, in particular of…
Excitonic giant-dipole potentials in cuprous oxide
Markus Kurz, Peter Grünwald, Stefan Scheel
In this work we predict the existence of a novel species of Wannier excitons when exposed to crossed electric and magnetic fields. In particular, we present a theory of giant-dipol…
