Phase transitions in a three dimensional U(1)×U(1) lattice London superconductor: Metallic superfluid and charge-4e superconducting states
Three dimensional lattice superconductor condensation coupling pulse measurement the current current coupling
2014/12/18
We consider a three dimensional lattice U(1)×U(1) and [U(1)]N superconductors in the London limit with individually conserved condensates. The U(1)×U(1) problem, generically, has two types of intercom...

Multi-step magnetization Ising model Shastry–Sutherland lattice Monte Carlo simulation
2016/12/2
The magnetization behaviors and spin configurations of the classical Ising model on a Shastry-Sutherland lattice are investigated using Monte Carlo simulations, in order to understand the fascinating ...
Lattice Results for Low Moments of Light Meson Distribution Amplitudes
Low Moments of Light Meson Distribution Amplitudes

As part of the UKQCD and RBC collaborations’ Nf = 2+1 domain-wall fermion phenomenology
programme, we calculate the first two moments of the light-cone distribution amplitudes of the
pseudoscalar me...
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...
Coulomb interaction effects and electron spin relaxation in the 1d Kondo lattice model
Ludwig-Maximilians-Universit¨at M¨unchen University of Queensland
2010/11/23
We study the effects of the Coulomb interaction in the one dimensional Kondo lattice model on
the phase diagram, the static magnetic susceptibility and electron spin relaxation. We show that onsite C...
Fractionalization in Three-Components Fermionic Atomic Gases in a One-Dimensional Optical Lattice
Fractionalization Three-Components Fermionic Atomic Gases a One-Dimensional Optical Lattice
2010/11/22
We study a three-components fermionic gas loaded in a one-dimensional optical trap at half-
lling. We nd that the system is fully gapped and may order into 8 possible phases: four 2kF
atomic densi...
Competition between supersolid phases and magnetisation plateaux in the frustrated easy-axis antiferromagnet on a triangular lattice
Competition supersolid phases magnetisation plateaux frustrated easy-axis antiferromagnet
2010/11/22
The majority of magnetic materials possess some degree of magnetic anisotropy, either at the level of a single ion, or in the exchange interactions between dierent magnetic ions. Where these exchange...
Supersolid in a one-dimensional optical lattice in the presence of a harmonic trap
Supersolid in a one-dimensional optical lattice harmonic trap
2010/11/19
We study a system of ultra-cold atoms possessing long range interaction (e.g. dipole-dipole interaction)in a one dimensional optical lattice in the presence of a confining harmonic trap. We have shown...
Dynamic Stimulation of Quantum Coherence in Lattice Bosons
Dynamic Stimulation Quantum Coherence in Lattice Bosons
2010/11/19
Thermal fluctuations tend to destroy long-range phase correlations. Consequently, bosons in a lattice will undergo a transition from a phase-coherent superfluid as the temperature rises. Contrary to c...

Ordinary matter is described by six fundamental parameters: three couplings (gravitational,
electromagnetic and strong) and three masses: the electron’s (me) and those of the up (mu)
and down (md) q...
