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…
Dynamics of one-dimensional Bose-Josephson Junction in a Box Trap: From Coherent Oscillations to Many-Body Dephasing and Dynamical Freezing
Abhik Kumar Saha, L. F. Calazans de Brito, Rhombik Roy +4
Understanding how coherent quantum dynamics give way to correlation-dominated behavior in low-dimensional systems remains a central challenge in quantum many-body physics. Here, we…
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…
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…
