Thermal aspects of interacting quantum gases in Lorentz-violating scenarios [PDF]
The European Physical Journal Plus, 2020 In this work, we study the interaction of quantum gases in Lorentz-violating scenarios considering both boson and fermion sectors. In the latter case, we investigate the consequences of a system governed by scalar, vector, pseudovector and tensor ...

Strong correlations in lossy one-dimensional quantum gases: From the quantum Zeno effect to the generalized Gibbs ensemble [PDF]
Physical Review A, 2020 We consider strong two-body losses in bosonic gases trapped in one-dimensional optical lattices. We exploit the separation of timescales typical of a system in the many-body quantum Zeno regime to establish a connection with the theory of the time ...

How does geometry affect quantum gases? [PDF]
International Journal of Modern Physics A, 2020 In this work, we study the thermodynamic functions of quantum gases confined to spaces of various shapes, namely, a sphere, a cylinder and an ellipsoid.

Gibbs mixing of partially distinguishable photons with a polarising beamsplitter membrane
New Journal of Physics, 2020 For a thought experiment concerning the mixing of two classical gases, Gibbs concluded that the work that can be extracted from mixing is determined by whether or not the gases can be distinguished by a semi-permeable membrane; that is, the mixing work ...

Long-Lived and Transient Supersolid Behaviors in Dipolar Quantum Gases [PDF]
Physical Review X, 2019 By combining theory and experiments, we demonstrate that dipolar quantum gases of both $^{166}$Er and $^{164}$Dy support a state with supersolid properties, where a spontaneous density modulation and a global phase coherence coexist.

Grüneisen parameters: Origin, identity, and quantum refrigeration
Physical Review Research, 2020 In solid-state physics, the Grüneisen parameter (GP) was first introduced to study the effect of volume change of a crystal lattice on its vibrational frequencies and has since been widely used to investigate the characteristic energy scales of systems ...

Towards a low-resolution infrared sounder for monitoring atmospheric ammonia (NH3) at high spatial resolution [PDF]
Atmospheric Measurement TechniquesOver the past decade, hyperspectral infrared sounders on satellites have offered global measurements of atmospheric ammonia (NH3), providing valuable insights into its sources. However, due to their coarse spatial resolution and gaps in spatial coverage,

Theory of radio-frequency spectroscopy of impurities in quantum gases [PDF]
, 2020 We present a theory of radio-frequency spectroscopy of impurities interacting with a quantum gas at finite temperature. By working in the canonical ensemble of a single impurity, we show that the impurity spectral response is directly connected to the ...

Optical spin conductivity in ultracold quantum gases
Physical Review Research, 2022 We show that the optical spin conductivity, which is a small ac response of a bulk spin current and elusive in condensed matter systems, can be measured in ultracold atoms. We demonstrate that this conductivity contains rich information on quantum states
