Beyond Spontaneously Broken Symmetry in Bose-Einstein Condensates
Condensate treatment stage bell inequality particles quantum Angle the population oscillation
2014/12/19
Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot treat phase off-diagonal effects, and thus cannot explain Bell inequality violations. We describe another situation that is bey...
Topological semimetal: a probable new state of quantum optical lattice gases protected by D$_4$ symmetry
Topological semimetal quantum optical lattice gases
2010/11/24
The use of optical lattices plays a versatile role in advancing knowledge of correlated quantum
matter. The recent orbital lattice experimentsof Wirth et al [1{3] open up a new thrust towards
discov...
Penetration of nonquantized magnetic flux through a domain-wall bend in time-reversal symmetry broken superconductors
Penetration of nonquantized magnetic flux domain-wall superconductors
2010/11/22
It has been proposed that the superconductivity of Sr2RuO4 is characterized by pairing that is
unconventional and, furthermore, spontaneously breaks time-reversal symmetry. However, one of
the key e...
Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD exact chiral symmetry
2011/1/13
Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...

Topological phases flat surface bands superconductors without inversion symmetry
2010/11/18
We examine different topological phases in three-dimensional non-centrosymmetric superconductors with time-reversal symmetry by using three different types of topological invariants. Due to the bulk b...
Heavy Quark Spin Symmetry and Heavy Baryons: Electroweak Decays
Heavy Quark Spin Symmetry Heavy Baryons Electroweak Decays
2011/1/7
Heavy quark spin symmetry is discussed in the context of single and doubly heavy baryons. A
special attention is paid to the constraints/simplifications that this symmetry imposes on the non-relativi...
Time reparametrization symmetry in a short-range p-spin model
Time reparametrization symmetry short-range p-spin model
2010/11/19
We explore the existence of time reparametrization symmetry in the p-spin model. Using the Martin-Siggia-Rose generating functional, we analytically probe the long-time dynamics. We perform a Renormal...

Vibrating rods Anderson localization Wannier-Stark ladders Symmetry breaking
2010/11/19
Locally periodic rods, which show approximate invariance with respect to translations,
are constructed by joining N unit cells. The spectrum then shows a band spectrum. We then break
the local perio...

The Chiral Magnetic Effect and chiral symmetry breaking in SU(3) quenched lattice gauge theory
Chiral Magnetic Effect chiral symmetry SU(3) quenched lattice gauge theory
2011/1/14
We study some properties of the non-Abelian vacuum induced by strong external magnetic field.
We perform calculations in the quenched SU(3) lattice gauge theory with tadpole-improved

2011/1/4
We present precise tests of CP and CPT symmetry based on the full dataset of K ! ππ decays
collected by the KTeV experiment at Fermi National Accelerator Laboratory during 1996, 1997, and 1999.
