Wu, Yong-Shi | Moyal representation of the string field star product in the presence of a B background | In this paper we show that in the presence of an antisymmetric tensor B background, Witten's star algebra for open string fields persists to possess the structure of a direct product of commuting Moyal pairs. The interplay between the noncommutativity due to three-string overlap and that due to the ... | String theory; Moyal pairs; Moyal structure; Noncommutativity | 2003-06 |

Mattis, Daniel C. | Partially frustrated Ising models in two dimensions | We examine ordered, periodic, Ising models on a sq lattice at varying levels x of frustration. The thermodynamic singularity of the fully frustrated model (x=1) is at T=0 while those of partially frustrated lattices (0<x<1) occur at finite Tc . The critical indices in the partially frustrated latti... | Antiferromagnets; Frustration; Ising chain | 2003-06 |
