Super-Tonks-Girardeau Quench in the Extended Bose-Hubbard Model
Maciej Marciniak, Maciej Åebek, Jakub KopyciÅski +3
We investigate the effect of a quench from a one-dimensional gas with strong and repulsive local interactions to a strongly attractive one, known as the super-Tonks-Girardeau effec…

Long-Baseline Atom Interferometry
Antun Balaz, Diego Blas, Oliver Buchmueller +50
Long-baseline atom interferometry is a promising technique for probing various aspects of fundamental physics, astrophysics and cosmology, including searches for ultralight dark ma…

Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
Maciej Åebek, Jakub KopyciÅski, Wojciech Górecki +2
A one-dimensional bosonic gas with strong contact repulsion and attractive non-local interactions may form a quantum droplet with a flat-top density profile. We focus on a system i…
