In Situ Coherence Measurements of Scattered Light in Magnetically Trapped Cold Atomic Clouds: Probe-Driven Atomic Dynamics
Amilson R. Fritsch, Hector Letellier, Leonardo Lima da Silva +4
The use of temporal correlations in scattered photons to probe the microscopic dynamics of ultracold quantum gases has emerged as a powerful, minimally destructive approach for in…
Preparing a Thermofield Double State with Feedback Quantum Algorithms
Guilherme E. L. Pexe, Lucas A. M. Rattighieri, Felipe F. Fanchini +2
The efficient preparation of correlated thermal states, such as the Thermofield Double (TFD) state, is a fundamental prerequisite for simulating quantum gravity models and many-bod…
Universal scaling and relaxation in decaying turbulence of Bose gases
Arnol D. GarcÃa-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. GarcÃa-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…
Evolution of density variations in a trapped atomic superfluid driven into turbulence
Michelle A. Moreno-Armijos, Leandro Machado, Arnol D. GarcÃa-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…
Observation of Relaxation Stages in a Nonequilibrium Closed Quantum System: Decaying Turbulence in a Trapped Superfluid
M. A. Moreno-Armijos, A. R. Fritsch, A. D. GarcÃa-Orozco +7
The dynamics of non-equilibrium closed quantum systems and their route to thermalization are of fundamental interest to several fields, from cosmology to particle physics. However,…
