We address static and dynamical properties of one-dimensional (1D) quantum droplets
(QDs) under the action of local potentials in the form of narrow wells and barriers. The …

The interaction of matter–wave solitons with a potential barrier is a fundamentally important
problem, and the splitting and subsequent recombination of the soliton by the barrier is 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 …

We investigate numerically the collisions of two distinguishable quantum matter-wave bright
solitons in a one-dimensional harmonic trap. We show that such collisions can be used to …

We study bright solitons in the Gross-Pitaevskii equation as they are split and recombined in
a low-energy system. We present analytic results determining the general region in which a …

Based on the formal analogy between soliton tunneling through a classically forbidden
potential barrier and–particle tunneling and decay we introduce a 'toy solitonic model of a …

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

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

We study the flow of bright solitons through two asymmetric potential wells. The scattering of
a soliton by a certain type of single potential wells, eg, Gaussian or Rosen-Morse, is …

We report systematic numerical simulations of the collision of a bright matter-wave soliton
made of Bose-condensed alkali-metal atoms through a narrow potential barrier by using the …
