Theory of the edge states in fractional quantum Hall effects

XG Wen - International journal of modern physics B, 1992 - World Scientific
The dynamical theory of the edge excitations of generic fractional quantum Hall (FQH) states
is summarized and expanded. The low energy effective theory of the edge excitations for the …

QUEST-DMC superfluid He detector for sub-GeV dark matter

QUEST-DMC collaboration, S Autti, A Casey… - The European Physical …, 2024 - Springer
The focus of dark matter searches to date has been on Weakly Interacting Massive Particles
(WIMPs) in the GeV/c 2-TeV/c 2 mass range. The direct, indirect and collider searches in this …

Decay of Pure Quantum Turbulence in Superfluid

DI Bradley, DO Clubb, SN Fisher, AM Guénault… - Physical review …, 2006 - APS
We describe measurements of the decay of pure superfluid turbulence in superfluid He 3-B,
in the low temperature regime where the normal fluid density is negligible. We follow the …

Many-body systems with non-Abelian statistics

B Blok, XG Wen - Nuclear Physics B, 1992 - Elsevier
We use conformal field theory to construct many-body hamiltonians whose ground states
support quasiparticle excitations with non-abelian statistics. Explicit forms of the many-body …

Generation and Detection of Quantum Turbulence in Superfluid

SN Fisher, AJ Hale, AM Guénault, GR Pickett - Physical Review Letters, 2001 - APS
We describe the first direct observations of turbulence in superfluid 3 He− B. The turbulence
is generated by a vibrating-wire resonator driven at velocities exceeding the pair-breaking …

Bose-glass melting in YBaCuO crystals with correlated disorder

L Krusin-Elbaum, L Civale, G Blatter, AD Marwick… - Physical review …, 1994 - APS
We report a sharp melting transition of the Bose glass in YBaCuO crystals with columnar
defects installed by the irradiation with 1 GeV Au ions. The melting B BG (T) is tracked at low …

Transition to Turbulence for a Quartz Tuning Fork in Superfluid 4He

DI Bradley, MJ Fear, SN Fisher, AM Guénault… - Journal of Low …, 2009 - Springer
We have studied the resonance of a commercial quartz tuning fork immersed in superfluid 4
He, at temperatures between 5 mK and 1 K, and at pressures between zero and 25 bar. The …

Emission of Discrete Vortex Rings by a Vibrating Grid In Superfluid : <?format ?>A Precursor to Quantum Turbulence

DI Bradley, DO Clubb, SN Fisher, AM Guénault… - Physical review …, 2005 - APS
We report a transition in the vorticity generated by a grid moving in the B phase of superfluid
He 3 at T≪ T c. The evolution of the vorticity after arresting the grid shows a dramatic …

Potential Dark Matter Detector? The Detection of Low Energy Neutrons by Superfluid He

DI Bradley, YM Bunkov, DJ Cousins, MP Enrico… - Physical review …, 1995 - APS
Using an existing experiment we have demonstrated in a pilot study that superfluid 3 He at
100 μK can be used as a nuclear recoil detector sensitive to neutron and γ interactions …

Direct measurement of the energy dissipated by quantum turbulence

DI Bradley, SN Fisher, AM Guénault, RP Haley… - Nature Physics, 2011 - nature.com
The lack of a general solution to the governing Navier–Stokes equations means that there is
no fundamental theory of turbulence. In the simpler case of pure quantum turbulence, the …
