Landau effective interaction between quasiparticles in a Bose-Einstein condensate

A Camacho-Guardian, GM Bruun - Physical Review X, 2018 - APS
Landau's description of the excitations in a macroscopic system in terms of quasiparticles
stands out as one of the highlights in quantum physics. It provides an accurate description of …

First and second sound in a compressible 3D Bose fluid

TA Hilker, LH Dogra, C Eigen, JAP Glidden, RP Smith… - Physical Review Letters, 2022 - APS
The two-fluid model is fundamental for the description of superfluidity. In the nearly
incompressible liquid regime, it successfully describes first and second sound …

Tuneable homogeneous Bose fluids close to and far from equilibrium

L Dogra - 2024 - repository.cam.ac.uk
This thesis describes experiments with an ultracold weakly interacting Bose gas of 39 K in a
3-dimensional homogeneous optical trap. We expound three phenomena in different …
