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…
Beyond-mean-field phases of rotating dipolar condensates
Paolo Molignini
Rotating dipolar Bose-Einstein condensates exhibit rich physics due to the interplay of long-range interactions and rotation, leading to unconventional vortex structures and strong…
Stability of quasicrystalline ultracold fermions to dipolar interactions
Paolo Molignini
Quasiperiodic potentials can be used to interpolate between localization and delocalization in one dimension. With the rise of optical platforms engineering dipolar interactions, a…
Interaction quench of dipolar bosons in a one-dimensional optical lattice
Paolo Molignini, Barnali Chakrabarti
A Tonks-Girardeau (TG) gas is a highly correlated quantum state of strongly interacting bosons confined to one dimension, where repulsive interactions make the particles behave lik…
Stability of dipolar bosons in a quasiperiodic potential
Paolo Molignini, Barnali Chakrabarti
Quasiperiodic potentials and dipolar interactions each impose long-range order in quantum systems, but their interplay unlocks a rich landscape of unexplored quantum phases. In thi…
Unbounded entropy production and violent fragmentation for repulsive-to-attractive interaction quench in long-range interacting systems
P. Molignini, B. Chakrabarti
We study the non-equilibrium dynamics of a one-dimensional Bose gas with long-range interactions that decay as ). We investigate exotic dynamics w…
