Effective three-body interactions for bosons in a double-well confinement
When describing the low-energy physics of bosons in a double-well potential with a high barrier between the wells and sufficiently weak atom-atom interactions, one can to a good approximation ignore
Spectral Structure and Many-Body Dynamics of Ultracold Bosons in a Double-Well
TLDR
This work explores the dynamical behavior of the particles launched either at the single-particle ground state or saddle-point energy, in a time-independent potential, and characterization of the cross-over from diabatic to quasi-adiabatic evolution under finite-time switching of the potential barrier.
Dynamical properties of a few mass-imbalanced ultra-cold fermions confined in a double-well potential
A comprehensive analysis of the exact unitary dynamics of two-component mass-imbalanced fermions in a one-dimensional double-well potential is accomplished by considering the total number of
Impact of the transverse direction on the many-body tunneling dynamics in a two-dimensional bosonic Josephson junction
TLDR
The detailed mechanism of the tunneling process is unraveled by analyzing the evolution in time of the survival probability, depletion and fragmentation, and the many-particle position, momentum and angular-momentum expectation values and their variances.
Many-body quantum metrology with scalar bosons in a single potential well
We theoretically investigate the possibility of performing high precision estimation of an externally imposed acceleration using scalar bosons in a single-well trap. We work at the level of a
Many-body quantum dynamics of an asymmetric bosonic Josephson junction
The out-of-equilibrium quantum dynamics of an interacting Bose gas trapped in a 1D asymmetric double-well potential is studied by solving the many-body Schr\"odinger equation numerically accurately.
One-dimensional mixtures of several ultracold atoms: a review.
TLDR
The recent advances on trapped Bose-Fermi mixtures are described, which allow for a theoretical combination of previous concepts, well illustrating the importance of quantum statistics and inter-particle interactions.
Decay properties of unstable Tonks-Girardeau gases from a split trap
We study the decay properties of Tonks-Girardeau gases escaping from a double-well potential. Initially, the gases are constrained between two infinite $\delta$ barriers with an on-center
Revisiting the dynamics of Bose-Einstein condensates in a double well by deep learning with a hybrid network
TLDR
This work proposes a novel learning method based on a hybrid network integrating two different kinds of neural networks: Long Short-Term Memory (LSTM) and Deep Residual Network (ResNet) in order to overcome the difficulty met in numerically simulating strongly-oscillating dynamical evolutions of physical systems.
