Mean Field Approximation of IIB Matrix Model and Emergence of Four Dimensional Space-Time
H. Kawai, S. Kawamoto, T. Kuroki +2
For the purpose of analyzing non-perturbative dynamics of string theory, Nishimura and Sugino have applied an improved mean field approximation (IMFA) to IIB matrix model. We have…
Correspondence between Noncommutative Soliton and Open String/D-brane System via Gaussian Damping Factor
B. Chen, H. Itoyama, T. Matsuo +1
The gaussian damping factor (g.d.f.) and the new interaction vertex with the symplectic tensor are the characteristic properties of the N-point scalar-vector scattering amplitudes…
Worldsheet and Spacetime Properties of p-p' System with B Field and Noncommutative Geometry
B. Chen, H. Itoyama, T. Matsuo +1
We study worldsheet and spacetime properties of the p-p' (p < p') open string system with constant B_{ij} field viewed from the Dp' brane. The description of this system in terms o…
p-p' System with B-field, Branes at Angles and Noncommutative Geometry
B. Chen, H. Itoyama, T. Matsuo +1
We study the generic system in the presence of constant NS 2-form field. We derive properties concerning with the noncommutativity of D-brane worldvolume, the…
Berry's Connection and USp(2k) Matrix Model
H. Itoyama, T. Matsuo
Berry's connection is computed in the USp(2k) matrix model. In T dualized quantum mechanics, the Berry phase exhibits a residual interaction taking place at a distance m_(f) from t…
