Scissors modes in generalized Gross-Pitaevskii equations
Oleksandr V. Marchukov, Neelam Shukla, Bastien Humbert +3
We investigate scissors modes in nonlinear systems with arbitrary power-law dependence of the nonlinear term. Through analytical derivation, we establish a general expression demon…

Effective two- and three-body interactions between dressed impurities in a tilted double-well potential
F. Theel, A. G. Volosniev, D. Diplaris +3
We explore the impact and scaling of effective interactions between two and three impurity atoms, induced by a bosonic medium, on their density distributions. To facilitate the det…

From spontaneous to explicit symmetry breaking in a finite-sized system: Bosonic bound states of an impurity
L. Chergui, F. Brauneis, T. Arnone Cardinale +3
The presence of a single attractive impurity in an ultracold repulsive bosonic system can drive a transition from a homogeneous to a localized state, as we here show for a one-dime…
