Triggering recollisions with XUV pulses: Imprint of recolliding periodic orbits
Jonathan Dubois, Angel Jorba
We consider an electron in an atom driven by an infrared (IR) elliptically polarized laser field after its ionization by an ultrashort extreme ultraviolet (XUV) pulse. We find that…
Non-adiabatic dynamics in Rydberg gases with random atom positions
Ritesh Pant, Rajat Agrawal, Sebastian Wüster +1
Assemblies of highly excited Rydberg atoms in an ultracold gas can be set into motion by a combination of van-der-Waals and resonant dipole-dipole interactions. Thereby, the collec…
Scattering of two particles in a 1D lattice
Seth T. Rittenhouse, P. Giannakeas, Nirav P. Mehta
This study concerns the two-body scattering of particles in a one-dimensional periodic potential. A convenient ansatz allows for the separation of center-of-mass and relative motio…
Non-adiabatic ionization with tailored laser pulses
Sajad Azizi, Ulf Saalmann, Jan M Rost
Non-adiabatic photo-ionization is difficult to control as it relies on the derivatives of the envelope and not on phase-details of the short ionizing pulse. Here, we introduce a ca…
Coherently delocalized states in dipole interacting Rydberg ensembles: the role of internal degeneracies
Ghassan Abumwis, Christopher W. Wächtler, Matthew T. Eiles +1
We investigate the effect of degenerate atomic states on the exciton delocalization of dipole-dipole interacting Rydberg assemblies. Using a frozen gas and regular one-, two-, and…
Synthetic dimension-induced conical intersections in Rydberg molecules
Frederic Hummel, Matthew T. Eiles, Peter Schmelcher
We observe a series of conical intersections in the potential energy curves governing both the collision between a Rydberg atom and a ground-state atom and the structure of Rydberg…
