Complex Langevin analysis of the spontaneous breaking of 10D rotational symmetry in the Euclidean IKKT matrix model
Konstantinos N. Anagnostopoulos, Takehiro Azuma, Yuta Ito +3
The IKKT matrix model is a promising candidate for a nonperturbative formulation of superstring theory, in which spacetime is conjectured to emerge dynamically from the microscopic…
Scalar Cosmological Perturbations in M-theory with Higher Derivative Corrections
Kazuho Hiraga, Yoshifumi Hyakutake
We investigate the inflationary expansion of the universe induced by higher curvature corrections in M-theory. The inflationary evolution of the geometry is discussed in ref.[1], t…
Systematic study of the SO(10) symmetry breaking vacua in the matrix model for type IIB superstrings
Jun Nishimura, Toshiyuki Okubo, Fumihiko Sugino
We study the properties of the space-time that emerges dynamically from the matrix model for type IIB superstrings in ten dimensions. We calculate the free energy and the extent of…
Spontaneous breaking of the rotational symmetry in dimensionally reduced super Yang-Mills models
Tatsumi Aoyama, Jun Nishimura, Toshiyuki Okubo
We investigate the spontaneous breaking of the SO(D) symmetry in matrix models, which can be obtained by the zero-volume limit of pure SU(N) super Yang-Mills theory in D = 6, 10 di…
Vortices as Instantons in Noncommutative Discrete Space: Use of Coordinates
Hideharu Otsu, Toshiro Sato, Hitoshi Ikemori +1
We show that vortices of Yang-Mills-Higgs model in space can be regarded as instantons of Yang-Mills model in space. For this, we construct the noncommu…
Non Abelian Vortices as Instantons on Noncommutative Discrete Space
Hitoshi Ikemori, Shinsaku Kitakado, Hideharu Otsu +1
There seems to be close relationship between the moduli space of vortices and the moduli space of instantons, which is not yet clearly understood from a standpoint of the field the…
Solitons of Sigma Model on Noncommutative Space as Solitons of Electron System
H. Otsu, T. Sato, H. Ikemori +1
We study the relationship of soliton solutions for electron system with those of the sigma model on the noncommutative space, working directly in the operator formalism. We find th…
Lost equivalence of nonlinear sigma and models on noncommutative space
H. Otsu, T. Sato, H. Ikemori +1
We show that the equivalence of nonlinear sigma and models which is valid on the commutative space is broken on the noncommutative space. This conclusion is arrived at thr…
New BPS Solitons in 2+1 Dimensional Noncommutative CP^1 Model
H. Otsu, T. Sato, H. Ikemori +1
Investigating the solitons in the non-commutative model, we have found a new set of BPS solitons which does not have counterparts in the commutative model.
