Supersolid Phase of Hard-Core Bosons on a Triangular Lattice
Ultra stereo core bosons triangular lattice ising spin magnetic field
2014/12/20
We study properties of the supersolid phase observed for hard-core bosons on the triangular lattice near half-integer filling factor, and the phase diagram of the system at finite temperature. We find...
Luttinger Liquid in the Core of a Screw Dislocation in Helium-4
Monte carlo simulation hexagonal shaft screw crystals superfluids screw dislocation
2014/12/20
On the basis of first-principles Monte Carlo simulations we find that the screw dislocation along the hexagonal axis of an hcp 4He crystal features a superfluid (at T→0) core. This is the first exampl...

On Core and Curvature Corrections used in Straight-Line Vortex Filament Methods
Core and Curvature Corrections Straight-Line Vortex Filament Methods Computational Physics
2012/4/24
The convergence characteristics of two viscous core corrections as used in straight-line segmentation methods are rigorously analysed. These are \emph{curvature corrections} that account for the induc...
Validity of Viscous Core Correction Models for Self-Induced Velocity Calculations
Validity of Viscous Core Correction Models Self-Induced Velocity Calculations Computational Physics
2012/4/20
Viscous core correction models are used in free wake simulations to remove the infinite velocities at the vortex centreline. It will be shown that the assumption that these corrections converge to the...
Ionization-induced asymmetric self-phase modulation and universal modulational instability in gas-filled hollow-core photonic crystal fibers
Ionization-induced asymmetric self-phase modulation universal modulational instability gas-filled hollow-core photonic crystal fibers Optics
2012/4/20
We study theoretically the propagation of relatively long pulses with ionizing intensities in a hollow-core photonic crystal fiber filled with a Raman-inactive gas. Due to photoionization, previously ...

Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...
On $p$-adic Gibbs Measures for Hard Core Model on a Cayley Tree
Cayley trees hard core interaction Gibbs measures translation invariant measures periodic measures
2011/9/20
Abstract: In this paper we consider a nearest-neighbor $p$-adic hard core (HC) model, with fugacity $\lambda$, on a homogeneous Cayley tree of order $k$ (with $k + 1$ neighbors). We focus on $p$-adic ...
In this work we investigate small clusters of helium atoms using the hyperspherical harmonic basis.
The Role of Collective Neutrino Flavor Oscillations in Core-Collapse Supernova Shock Revival
Core-Collapse Supernova Shock Revival Neutrino
2011/7/21
We explore the effects of collective neutrino flavor oscillations due to neutrino-neutrino interactions on the neutrino heating behind a stalled core-collapse supernova shock. We carry out axisymmetri...
Soliton self-frequency blue-shift in gas-filled hollow-core photonic crystal fibers
self-frequency blue-shift photonic crystal fibers
2011/9/7
We show theoretically that the photoionization process in a hollow-core photonic crystal fiber filled with a Raman-inactive noble gas leads to a constant acceleration of solitons in the time domain wi...
In this work we investigate small clusters of helium atoms using the hyperspherical harmonic basis. We consider systems with A = 2, 3, 4, 5, 6 atoms with an inter-particle potential which does not pre...

2010/12/31
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension

Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
