Universal dynamics of a turbulent superfluid Bose gas

AD García-Orozco, L Madeira, MA Moreno-Armijos… - Physical Review A, 2022 - APS
We study the emergence of universal scaling in the time-evolving momentum distribution of
a harmonically trapped three-dimensional Bose-Einstein condensate, parametrically driven …

Dynamics of ultracold bosons in artificial gauge fields—Angular momentum, fragmentation, and the variance of entropy

AUJ Lode, S Dutta, C Lévêque - Entropy, 2021 - mdpi.com
We consider the dynamics of two-dimensional interacting ultracold bosons triggered by
suddenly switching on an artificial gauge field. The system is initialized in the ground state of …

Cold atoms beyond atomic physics

L Madeira, VS Bagnato - Brazilian Journal of Physics, 2021 - Springer
In the last 25 years, much progress has been made producing and controlling Bose-Einstein
condensates (BECs) and degenerate Fermi gases. The advances in trap**, cooling, and …

Photon cooling: Linear versus nonlinear interactions

A Hovhannisyan, V Stepanyan, AE Allahverdyan - Physical Review A, 2022 - APS
Linear optics imposes a relation that is more general than the second law of
thermodynamics: For modes undergoing a linear evolution, the full mean occupation …

Density functional theory of superfluid helium at finite temperatures

A Long, J Eloranta - The Journal of Chemical Physics, 2021 - pubs.aip.org
A density functional theory-based method is developed to describe the static and dynamic
response of superfluid helium at finite temperatures. The model relies on the well …

Onset and Irreversibility of Granulation of Bose-Einstein condensates under Feshbach Resonance Management

AUJ Lode, MC Tsatsos, PG Kevrekidis… - arxiv preprint arxiv …, 2021 - arxiv.org
Granulation of quantum matter--the formation of persistent small-scale patterns--is realized
in the images of quasi-one-dimensional Bose-Einstein condensates perturbed by a …

[HTML][HTML] Characteristic length scale during the time evolution of a turbulent Bose-Einstein condensate

L Madeira, AD García-Orozco, MA Moreno-Armijos… - Symmetry, 2021 - mdpi.com
Quantum turbulence is characterized by many degrees of freedom interacting non-linearly to
produce disordered states, both in space and in time. In this work, we investigate the …

Thermodynamic Balance in the Tornado Theory

P Bělík, DP Dokken, MM Shvartsman - arxiv preprint arxiv:2407.05345, 2024 - arxiv.org
This work addresses the thermodynamics of the initial formation (genesis) of tornado-like
vortices. In particular, it discusses how the thermodynamics of discrete vortices in a two …
