Eighth-order phase-field-crystal model for two-dimensional crystallization
Eighth-order phase-field-crystal model two-dimensional crystallization
2010/11/25
We present a derivation of the recently proposed eighth order phase field crystal model [Jaatinen et al. , Phys. Rev. E 80, 031602 (2009)] for the crystallization of a solid from an undercooled melt.
Crystallization of the Lewis-Wahnström ortho-terphenyl model
Crystallization Lewis-Wahnströ m ortho-terphenyl model
2010/11/19
Crystallization is observed during long molecular dynamics simulations of bent trimers, a molecular model proposed by Lewis and Wahnstrom for ortho-terphenyl. In the crystal, the three spheres that m...

Quenches in quantum many-body systems One-dimensional Bose-Hubbard model
2010/11/17
In his Comment [see preceding Comment, Phys. Rev. A 82, 037601 (2010)] on the paper by Roux [Phys.Rev. A 79, 021608(R) (2009)], Rigol argued that the energy distribution after a quench is not related ...
Supersymmetry restoration in lattice formulations of 2D $\mathcal{N}=(2,2)$ WZ model based on the Nicolai map
Supersymmetry lattice field theory Nicolai map continuum
2011/1/13
For lattice formulations of the two-dimensional N = (2, 2) Wess–Zumino (2D N = (2, 2) WZ) model on the basis of the Nicolai map, we show that supersymmetry (SUSY) and other symmetries are restored in ...
Worm Monte Carlo study of the honeycomb-lattice loop model
Monte Carlo Worm algorithm Loop model
2010/11/19
We present a Markov-chain Monte Carlo algorithm of worm type that correctly simulates the
O(n) loop model on any (finite and connected) bipartite cubic graph, for any real n > 0, and
any edge weight...
Phase Structure of Anisotropic Antiferromagnetic Heisenberg Model on Layered Triangular Lattice: Spiral State and Deconfined Spin Liquid
Phase Structure Deconfined Spin Liquid
2010/10/27
In the present paper, we study spin- 1 2 antiferromagnetic (AF) Heisenberg model on layered anisotropic triangular lattice and obtain its phase structure. We use the Schwinger bosons for representing ...
Au Nanoparticle Clusters: A New System to Model Hopping Conduction
nanoparticles Coulomb blockade hopping conduction
2010/4/12
We study electrical transport through self-assembled Au nanoparticle clusters which can be viewed as a new model system to study hopping transport. The physics of such systems is governed by two param...
