Self-limiting electrostriction of a single ion in an ultracold polar gas: From mesoscopic ions to crystalline molecular rings
Ruiren Shi, Saajid Chowdhury, Leon Karpa +1
We investigate the self-assembly of polar molecules around a single ion immersed in an ultracold, dilute two-dimensional molecular gas. The ion aligns and attracts the molecules th…
Electric-field control of atom-molecule Feshbach resonances
Mara Meyer zum Alten Borgloh, Jule Heier, Fritz von Gierke +4
Ultracold molecules provide opportunities for exploring quantum matter, chemical dynamics and information processing thanks to their rich interactions, which can be controlled by e…
Two-photon-assisted collisions in ultracold gases of polar molecules II : Optical shielding of ultracold polar molecular collisions
Gohar Hovhannesyan, Charbel Karam, Romain Vexiau +4
We theoretically investigate the collisions between ultracold polar molecules in the presence of two lasers ensuring a Raman resonant transition on individual molecules to suppress…
Optical formation of ultracold NaK ground state molecules
Baraa Shammout, Leon Karpa, Silke Ospelkaus +2
We study the rovibronic transitions in NaK between its electronic ground state and its second excited state , to identify possible pathways for the creation of u…
Formation of ultracold triatomic molecules by electric microwave association
Baraa Shammout, Leon Karpa, Silke Ospelkaus +2
A theoretical model is proposed for the formation of ultracold ground-state triatomic molecules in weakly bound energy levels. The process is driven by the electric component of a…
Ultracold Interactions between Ions and Polar Molecules
Leon Karpa, Olivier Dulieu
We propose a platform for observing and controlling the interactions between atomic ions and a quantum gas of polar molecules in the ultracold regime. This approach is based on the…
