We present the first realization of a solitonic atom interferometer. A Bose-Einstein
condensate of 1× 10 4 atoms of rubidium-85 is loaded into a horizontal optical waveguide …

We elaborate a model of the interferometer which, unlike previously studied ones, uses a
local (δ-functional) nonlinear repulsive potential, embedded into a harmonic-oscillator …

We report on the production of K 39 matter-wave bright solitons, ie, one-dimensional matter
waves that propagate without dispersion thanks to attractive interactions. The volume of the …

We report a scheme for quantum sensing in ultracold atoms by utilizing an atom-
interferometer producing sub-Planck scale structures. The condensate is trapped in a hybrid …

Interference patterns associated with soliton–soliton interaction are investigated in detail.
We find that the temporal and spatial interference patterns exhibit quite different …

Particle delocalization is a common feature of quantum random walks in arbitrary lattices.
However, in the typical scenario a particle spreads over multiple sites and its evolution is not …

We investigate tunneling behavior between two bright solitons in a Bose–Einstein
condensate with attractive contact interactions between atoms. The explicit tunneling …

We observe nonlinear scattering of 39 K atomic bright solitons launched in a one-
dimensional (1D) speckle disorder. We directly compare it with the scattering of non …

Due to their coherence properties, dilute atomic gas Bose-Einstein condensates seem a
versatile platform for controlled creation of mesoscopically entangled states with a large …

We consider the interaction of two-component bright-bright solitons with a narrow potential
barrier (splitter) in the framework of a system of two Gross-Pitaevskii (nonlinear-Schrödinger) …
