Spin mixing induced dynamics of spinor solitons in Bose Einstein condensates
T. Panagos, A. Romero-Ros, G. C. Katsimiga +2
We explore soliton interactions in a homogeneous spinor Bose Einstein Condensate (BEC) in the presence of a magnetic field, focusing on dark bright dark and bright dark brigh…
Quantum Dynamics with Time-Dependent Neural Quantum States
Alejandro Romero-Ros, Javier Rozalén Sarmiento, Arnau Rios
We present proof-of-principle time-dependent neural quantum state (NQS) simulations to illustrate the ability of this approach to effectively capture key aspects of quantum dynamic…
Nonlinear stage of modulational instability in repulsive two-component Bose-Einstein condensates
S. Mossman, S. I. Mistakidis, G. C. Katsimiga +5
Modulational instability (MI) is a fundamental phenomenon in the study of nonlinear dynamics, spanning diverse areas such as shallow water waves, optics, and ultracold atomic gases…
Experimental realization of the Peregrine soliton in repulsive two-component Bose-Einstein condensates
A. Romero-Ros, G. C. Katsimiga, S. I. Mistakidis +5
We experimentally realize the Peregrine soliton in a highly particle-imbalanced two-component repulsive Bose-Einstein condensate in the immiscible regime. The effective focusing dy…
Observation of dense collisional soliton complexes in a two-component Bose-Einstein condensate
S. Mossman, G. C. Katsimiga, S. I. Mistakidis +5
Solitons are nonlinear solitary waves which maintain their shape over time and through collisions, occurring in a variety of nonlinear media from plasmas to optics. We present an e…
Theoretical and numerical evidence for the potential realization of the Peregrine soliton in repulsive two-component Bose-Einstein condensates
A. Romero-Ros, G. C. Katsimiga, S. I. Mistakidis +4
The present work is motivated by the recent experimental realization of the Townes soliton in an effective two-component Bose-Einstein condensate by B. Bakkali-Hassan et al. [Phys.…
On-demand generation of dark-bright soliton trains in Bose-Einstein condensates
A. Romero-Ros, G. C. Katsimiga, P. Kevrekidis +3
The controlled creation of dark-bright (DB) soliton trains in multi-component Bose-Einstein condensates (BECs) is a topic of ongoing interest. In this work we generalize earlier fi…
On-demand generation of dark soliton trains in Bose-Einstein condensates
A. Romero-Ros, G. C. Katsimiga, P. G. Kevrekidis +3
Matter-wave interference mechanisms in one-dimensional Bose-Einstein condensates that allow for the controlled generation of dark soliton trains upon choosing suitable box-type ini…
Controlled Generation of Dark-Bright Soliton Complexes in Two-Component and Spinor Bose-Einstein Condensates
A. Romero-Ros, G. C. Katsimiga, P. G. Kevrekidis +1
We report on the controlled creation of multiple soliton complexes of the dark-bright type in one-dimensional two-component, three-component and spinor Bose-Einstein condensates. T…
Dynamic structure function of two interacting atoms in 1D
David Ledesma, Alejandro Romero-Ros, Artur Polls +1
We consider two atoms trapped in a one-dimensional harmonic oscillator potential interacting through a contact interaction. We study the transition from the non-interacting to the…
