Grooving of a grain boundary by evaporation–condensation below the roughening transition
grain boundary evaporation–condensation below roughening transition
2015/10/16
The development of surface grooves at grain boundaries that intersect a planar surface is analyzed for the case that the evolution occurs below the thermodynamic roughening transition by evaporation–c...
The Dynamic Phase Transition for Decoding Algorithms
Error correction coding the random structure random graph random arrangement
2015/8/21
The state-of-the-art error correcting codes are based on large random constructions (random graphs, random permutations, . . . ) and are decoded by linear-time iterative algorithms. Because of these f...
Revealing the superfluid–Mott-insulator transition in an optical lattice

2014/12/22
We study (by an exact numerical scheme) the single-particle density matrix of ～103 ultracold atoms in an optical lattice with a parabolic confining potential. Our simulation is directly relevant to th...

2014/12/20
We report results of large-scale Monte Carlo simulations of superfluid-insulator transitions in disordered commensurate 2D bosonic systems. In the off-diagonal disorder case, we find that the transiti...

We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
Absence of a Direct Superfluid to Mott Insulator Transition in Disordered Bose Systems

2014/12/19
We prove the absence of a direct quantum phase transition between a superfluid and a Mott insulator in a bosonic system with generic, bounded disorder. We also prove the compressibility of the system ...

2014/12/19
The superfluid transition of a three-dimensional gas of hard-sphere bosons in a disordered medium is studied using quantum Monte Carlo methods. Simulations are performed in continuous space both in th...

Ultracold atoms optical lattice gas. Quantum multibody system such as quantum simulator
2014/12/19
Ultracold atomic gases in optical lattices have proven to be a controllable, tunable and clean implementation of strongly interacting quantum many-body systems. An essential prospect for such quantum ...

2012/6/14
Phase transitions waves in atomic chains with double-well potential play a fundamental role in materials science, but very little is known about their mathematical properties. In particular, the only ...

Ising model secondary phase transition General Physics
2012/4/20
Lttice-spin phonons are considered, which make the heat capacity at the critical temperature satisfy experimental observations better. There is a BEC phase transition in an Ising model attributable to...
