Hidden Ergodic Relaxation in the Quench Dynamics of a Bichromatic Mott Lattice
Áttis V. M. Marino, Rhombik Roy, M. A. Caracanhas +5
We investigate the nonequilibrium dynamics of strongly interacting bosons in a finite bichromatic Mott lattice following a sudden quench of the secondary lattice amplitude. The coe…
Universal scaling and relaxation in decaying turbulence of Bose gases
Arnol D. García-Orozco, Michelle A. Moreno-Armijos, Sarah Sab +2
Understanding the relaxation dynamics of isolated quantum systems remains a central challenge in nonequilibrium physics. In this short review, we discuss recent experimental and th…
Universal Behavior on the Relaxation Dynamics of Far-From-Equilibrium Quantum Fluids
Sarah Sab, Michelle A. Moreno-Armijos, Arnol D. García-Orozco +6
Investigating the initial conditions that lead many-body quantum systems to an out-of-equilibrium state is fundamental for understanding their thermalization dynamics. In this work…
Stability and Decay of Macrovortices in Rotating Bose Gases Beyond Mean Field
Paolo Molignini, M. A. Caracanhas, V. S. Bagnato +1
We study the formation, stability, and decay of macrovortices in a rotating Bose gas confined by a Mexican-hat potential with a multiconfigurational ansatz. By systematically inclu…
Dynamical localization of interacting ultracold atoms in one-dimensional quasi-periodic potentials
Attis V. M. Marino, M. A. Caracanhas, V. S. Bagnato +1
We present numerically exact non-equilibrium dynamics of a one-dimensional Bose gas in quasi-periodic lattice that plays an intermediate role between the long-ranged order and trul…
Evolution of density variations in a trapped atomic superfluid driven into turbulence
Michelle A. Moreno-Armijos, Leandro Machado, Arnol D. García-Orozco +3
In this work, we study the free decay of a turbulent trapped Bose gas by analyzing the temporal evolution of density variations extracted from absorption images. We introduce a par…
Interaction Quench Dynamics and Stability of Quantum Vortices in Rotating Bose-Einstein Condensates
L. A. Machado, B. Chatterjee, M. A. Caracanhas +3
We theoretically investigate the non-equilibrium dynamics of quantum vortices in a two-dimensional rotating Bose-Einstein condensate following an interaction quench. Using an ab in…
Nonlinear coherent modes and atom optics
V. I. Yukalov, E. P. Yukalova, V. S. Bagnato
By pumping energy into a trapped Bose-Einstein condensate it is possible to generate nonlinear coherent modes representing non-ground-state condensates. A Bose-condensed system of…
Spectroscopy of collective modes in a Bose-Einstein condensate: From single to double excitation periods
Leandro A. Machado, Lucas Madeira, Mônica A. Caracanhas +1
Collective modes are coherent excitations in Bose-Einstein condensates (BECs), and their study provides insight into the macroscopic quantum phenomena that govern these systems. Co…
Shape and size measurements of nonequilibrium Bose-Einstein condensates using image processing
J. P. G. Venassi, V. S. Bagnato, G. D. Telles
Bose-Einstein condensates have been the subject of intense research in recent years due to their potential applications in quantum computing and many other areas. However, measurin…

V. I. Yukalov, E. P. Yukalova, V. S. Bagnato
The review presents the methods of generation of nonlinear coherent excitations in strongly nonequilibrium Bose-condensed systems of trapped atoms and their properties. Non-ground-…
Universal scaling in far-from-equilibrium quantum systems: an equivalent differential approach
L. Madeira, A. D. García-Orozco, M. A. Moreno-Armijos +2
Recent progress in out-of-equilibrium closed quantum systems has significantly advanced the understanding of mechanisms behind their evolution towards thermalization. Notably, the…
