Tricritical point and wing structure in the itinerant ferromagnet UGe2
Tricritical point wing structure itinerant ferromagnet UGe2
2010/11/17
Precise resistivity measurements on the ferromagnetic superconductor UGe2 under pressure p and
magnetic field H reveal a previously unobserved change of the anomaly at the Curie temperature.
Therefo...

Long range chromomagnetic fields high temperature
2011/1/14
The magnetic mass of neutral gluons in Abelian chromomagnetic field at high temperature is calculated in SU(2) gluodynamics. It is noted that such type fields are spontaneously generated at high tempe...
Superposition states of ultracold bosons in rotating rings with a weak potential barrier
Superposition states ultracold bosons weak potential barrier
2010/11/23
We study ultracold bosons in a one-dimensional rotating ring lattice with a weak potential barrier well below unit filling. Due to the potential barrier the eigenstates are superpositions of different...
We investigate medium effects on mesonic screening lengths for QCD with 2-flavours of dynamical
staggered quarks on lattices with cutoff a=1/6T. Denoting the cross-over temperature by Tc,
we vary th...
A Spectroscopic Method to Measure the Superfluid Fraction of an Ultracold Atomic Gas
Spectroscopic Method Superfluid Fraction of an Ultracold Atomic Gas
2010/11/19
We perform detailed analytical and numerical studies of a recently proposed method for a spectroscopic measurement of the superfluid fraction of an ultracold atomic gas [N. R. Cooper and Z. Hadzibabic...
Spontaneously axisymmetry breaking phase in a binary mixture of spinor Bose-Einstein condensates
Spontaneously axisymmetry spinor Bose-Einstein condensates
2010/11/17
We study the ground state phases for a mixture of two atomic spin-1 Bose-Einstein condensates
(BECs) in the presence of a weak magnetic (B-) field. The ground state is found to contain a
broken-axis...
Spin and spin-isospin instabilities in asymmetric nuclear matter at zero and finite temperatures using Skyrme functionals
Spin and spin-isospin instabilities asymmetric nuclear matter zero finite temperatures Skyrme functionals
2011/1/6
Self-consistent mean field methods based on phenomenological Skyrme effective interactions are
known to exhibit spurious spin and spin-isospin instabilities both at zero and finite temperatures when ...
Integrability breakdown in longitudinaly trapped, one-dimensional bosonic gases
Integrability breakdown one-dimensional bosonic gases
2010/11/17
A system of identical bosons with short-range (contact) interactions is studied. Their motion is confined to one dimension by a tight lateral trapping potential and, additionally, subject to a weak ha...
Dynamical generation of phase-squeezed states in a two-component Bose-Einstein condensates
Dynamical generation of phase-squeezed states two-component Bose-Einstein condensates
2010/11/22
As an “input” state of a linear (Mach-Zehnder or Ramsey) interferometer, the phase-squeezed
state proposed by Berry and Wiseman exhibits the best sensitivity approaching to the Heisenberg
limit [Phy...

2011/1/13
We investigate baryon-baryon (BB) interactions in the 3-flavor full QCD simulations with degenerate quark masses for all flavors. The BB potentials in the orbital S-wave are extracted from the Nambu-B...

Fisher's zeros boundary of RG flows complex coupling space
2011/1/13
We discuss the possibility of extending the RG flows to complex coupling spaces. We argue
that the Fisher’s zeros are located at the boundary of the complex basin of attraction of IR fixed points.

A novel algorithm has been proposed for simulating thermal decomposition of atomic clusters at such low temperatures that the corresponding lifetimes are macroscopic and, hence, standard molecular dyn...

We investigate the long-time properties of the Ising-Glauber model on a periodic cubic lattice
after a quench to zero temperature. In contrast to the conventional picture from phase-ordering
