Strongly correlated quantum fluids: ultracold quantum gases, quantum chromodynamic plasmas and holographic duality [PDF]
New Journal of Physics, 2012 Strongly correlated quantum fluids are phases of matter that are intrinsically quantum mechanical and that do not have a simple description in terms of weakly interacting quasiparticles.

Quantum phase slips: from condensed matter to ultracold quantum gases. [PDF]
Philos Trans A Math Phys Eng Sci, 2017 Quantum phase slips (QPS) are the primary excitations in one-dimensional superfluids and superconductors at low temperatures. They have been well characterized in most condensed-matter systems, and signatures of their existence have been recently ...

Measuring work and heat in ultracold quantum gases [PDF]
New Journal of Physics, 2015 We propose a feasible experimental scheme to direct measure heat and work in cold atomic setups. The method is based on a recent proposal which shows that work is a positive operator valued measure (POVM). In the present contribution, we demonstrate that

Few-body physics in resonantly interacting ultracold quantum gases [PDF]
, 2017 We provide a general discussion on the importance of three-body Efimov physics for strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical representation, we discuss a universal classification of three-body systems in terms of ...

Nonlinear speed-ups in ultracold quantum gases [PDF]
Europhysics Letters, 2022 Quantum mechanics is an inherently linear theory. However, collective effects in many body quantum systems can give rise to effectively nonlinear dynamics. In the present work, we analyze whether and to what extent such nonlinear effects can be exploited

Enhancement effect of mass imbalance on Fulde-Ferrell-Larkin-Ovchinnikov type of pairing in Fermi-Fermi mixtures of ultracold quantum gases. [PDF]
Sci Rep, 2017 Ultracold two-component Fermi gases with a tunable population imbalance have provided an excellent opportunity for studying the exotic Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states, which have been of great interest in condensed matter physics. However,

Repulsive Fermi and Bose Polarons in Quantum Gases [PDF]
Atoms, 2022 Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary excitations of a many-particle background. In the field of ultracold atoms, the study of the associated impurity problem has attracted a growing interest over the last ...

Stability and sensitivity of interacting fermionic superfluids to quenched disorder [PDF]
Nature CommunicationsThe microscopic pair structure of superfluids has profound consequences on their properties. Delocalized pairs are predicted to be less affected by static disorder than localized pairs.

Thermal BCS-BEC Crossovers in Finite Systems [PDF]
EntropyWe investigate the thermal evolution of fermionic pairings in a finite-size SU(2) × SU(2) complex model, drawing an analogy to the BCS-BEC crossover in interacting quantum gases.
