Superfluidity of Grain Boundaries in Solid 4He
Quantum monte carlo simulation crystal cryogenic superfluid super fluid particles
2014/12/20
By large-scale quantum Monte Carlo simulations we show that grain boundaries in 4He crystals are generically superfluid at low temperature, with a transition temperature of the order of ～0.5 ...
Effects of boundaries and density inhomogeneity on states of vortex matter in Bose-Einstein condensates at finite temperature
Quantum vortices 3 d eddy current condensate vortex entanglement
2014/12/19
Most of the literature on quantum vortices predicting various states of vortex matter in three dimensions at finite temperatures in quantum fluids is based on the assumption of an extended and homogen...

Abstract: Based on empirical evidence, quantum eigenvalue equations appear to be strictly linear and gauge invariant. This work uses concise mathematics to show that quantum eigenvalue equations on a ...
Snell's law for particles moving on piecewise homogeneous two dimensional surface with linear boundaries
Snell's law two dimensional surface
2011/8/29
We study the properties of least time trajectories for particles moving on a two dimensional surface which consists of piecewise homogeneous regions. The particles are assumed to move with di erent co...
Spin chains with non-diagonal boundaries and trigonometric SOS model with reflecting end
Spin chains non-diagonal boundaries trigonometric SOS model
2010/12/24
In this paper we consider two a priori very different problems: construction of the eigenstates of the spin chains with non parallel boundary magnetic fields and computation of the partition function ...
Quantum relaxation after a quench in systems with boundaries
Quantum relaxation boundaries
2010/11/23
We study the time-dependence of the magnetization profile, ml(t), of a large finite open quantum Ising chain after a quench. We observe a cyclic variation, in which starting with an exponentially decr...
Inertial forces and dissipation on accelerated boundaries
High Energy Physics-Theory(hep-th) Quantum Physics(quant-ph)
2010/11/9
We study dissipative effects due to inertial forces acting on matter fields confined to accelerated boundaries in $1+1$, $2+1$, and $3+1$ dimensions. These matter fields describe the internal degrees ...

Gromov, Cauchy and causal boundaries for Riemannian, Finslerian and Lorentzian manifolds
Gromov Cauchy causal boundaries for Riemannian Finslerian Lorentzian manifolds
2010/12/21
Recently, the old notion of causal boundary for a spacetime V has been rede ned in a consistent way. The computation of this boundary @V on any standard conformally stationary spacetime V = R M, sug...
Single-crystal Grains and Grain Boundaries in Graphene Grown by Chemical Vapor Deposition
Single-crystal Grains Grain Boundaries Chemical Vapor Deposition
2010/11/25
Graphene has attracted enormous attention due to its numerous remarkable properties and wide range of potential applications. To fully realize its potential, graphene needs to be synthesized in large ...
