A primer on quantum fluids

  title={A primer on quantum fluids},
  author={Carlo F. Barenghi and Nick G. Parker},
  journal={arXiv: Quantum Gases},
This book introduces the theoretical description and properties of quantum fluids. The focus is on gaseous atomic Bose-Einstein condensates and, to a minor extent, superfluid helium, but the underlying concepts are relevant to other forms of quantum fluids such as polariton and photonic condensates. The book is pitched at the level of advanced undergraduates and early postgraduate students, aiming to provide the reader with the knowledge and skills to develop their own research project on… 

Vortices and vortex lattices in quantum ferrofluids

A review of the theory of vortices in dipolar Bose-Einstein condensate is given, exploring the interplay of magnetism with vorticity and contrasting this with the established behaviour in non-dipolar condensates.

Dynamics of a Vortex Lattice in an Expanding Polariton Quantum Fluid.

This report reports on the first experimental study of the Feynman-Onsager relation in a nonequilibrium polariton fluid, free to expand and rotate, and detects a small deviation from the Feysinger rule in terms of a transverse velocity component.

Synthetic superfluid chemistry with vortex-trapped quantum impurities

We explore the effect of using two-dimensional matter-wave vortices to confine an ensemble of bosonic quantum impurities. This is modelled theoretically using a mass-imbalanced homogeneous two

Modeling The Gross-Pitaevskii Equation using The Quantum Lattice Gas Method

We present an improved Quantum Lattice Gas (QLG) algorithm as a mesoscopic unitary perturbative representation of the mean eld Gross Pitaevskii (GP) equation for BoseEinstein Condensates (BECs). The

A new self-consistent approach of quantum turbulence in superfluid helium

We present the Fully cOUpled loCAl model of sUperfLuid Turbulence (FOUCAULT) that describes the dynamics of finite temperature superfluids. The superfluid component is described by the vortex

Tangled vortex lines: dynamics, geometry and topology of quantum turbulence

Near absolute zero, superfluid liquid helium displays quantum properties at macroscopic length scales. One property, superfluidity, means flow with zero viscosity. Another property, the existence of a

Hydrodynamics of a quantum vortex in the presence of twist

Abstract The equations governing the evolution of quantum vortex defects subject to twist are derived in standard hydrodynamic form. Vortex defects emerge as solutions of the Gross–Pitaevskii

Helicity in superfluids: Existence and the classical limit

In addition to mass, energy, and momentum, classical dissipationless flows conserve helicity, a measure of the topology of the flow. Helicity has far-reaching consequences for classical flows from

Microcavity Exciton‐Polariton Quantum Spin Fluids

Microcavity exciton‐polaritons are attractive quantum quasi‐particles resulting from strong light–matter coupling in a quantum‐well‐cavity structure. They have become one of the most stimulating

Quasistable quantum vortex knots and links in anisotropic harmonically trapped Bose-Einstein condensates

Long-time existence of topologically nontrivial configurations of quantum vortices in the form of torus knots and links in trapped Bose-Einstein condensates is demonstrated numerically within the



Bose-Einstein condensation

In 1924 the Indian physicist Satyendra Nath Bose sent Einstein a paper in which he derived the Planck law for black-body radiation by treating the photons as a gas of identical particles. Einstein

Controlled polarization of two-dimensional quantum turbulence in atomic Bose-Einstein condensates

We propose a scheme for generating two-dimensional turbulence in harmonically trapped atomic condensates with the novelty of controlling the polarization (net rotation) of the turbulence. Our scheme

Nobel Prize for Physics

THE formulation of de Broglie's wave-particle theory in 1924 and its experimental verification in 1927 by Dr. C. J. Davisson at New York and Prof. G. P. Thomson at Aberdeen mark an outstanding epoch

Numerical studies of vortices and dark solitons in atomic Bose-Einstein condensates

Dilute atomic Bose-Einstein condensates support intriguing macroscopic excitations in the form of quantized vortices and dark solitons. In this thesis we present extensive quantitative studies of the

Bright Solitary Matter Waves: Formation, Stability and Interactions

In recent years, bright soliton-like structures composed of gaseous Bose–Einstein condensates have been generated at ultracold temperature. The experimental capacity to precisely engineer the

Onsager vortex formation in Bose-Einstein condensates in two-dimensional power-law traps

We study computationally dynamics of quantised vortices in two-dimensional superfluid Bose-Einstein condensates confined in highly oblate power-law traps. We have found that the formation of large

We show that the concept of degeneracy is the key idea for understanding the quantum carpet woven by a particle in the box.
