Enhancing sensitivity to rotations with quantum solitonic currents
Piero Naldesi, Juan Polo Gomez, Vanja Dunjko +4
Quantum mechanics is characterized by quantum coherence and entanglement. After having discovered how these fundamental concepts govern physical reality, scientists have been devot…

Traces of integrability in scattering of one-dimensional dimers on a barrier
Juan Polo Gomez, Anna Minguzzi, Maxim Olshanii
We consider molecules made of two one-dimensional short-range-interacting bosonic atoms. We show that in the process of scattering of these molecules off a narrow barrier, odd inci…

Raise and fall of a bright soliton in an optical lattice
Piero Naldesi, Juan Polo Gomez, Anna Minguzzi +3
We study an ultracold atomic gas with attractive interactions in a one-dimensional optical lattice. We find that its excitation spectrum displays a quantum soliton band, correspond…
