Perturbative versus nonperturbative dynamics of the fuzzy S^2*S^2
Takehiro Azuma, Subrata Bal, Keiichi Nagao +1
We study a matrix model with a cubic term, which incorporates both the fuzzy S^2*S^2 and the fuzzy S^2 as classical solutions. Both of the solutions decay into the vacuum of the pu…
Dynamical generation of gauge groups in the massive Yang-Mills-Chern-Simons matrix model
Takehiro Azuma, Subrata Bal, Jun Nishimura
It has been known for some time that the dynamics of k coincident D-branes in string theory is described effectively by U(k) Yang-Mills theory at low energy. While these configurat…
Fuzzy Torus in Matrix Model
Subrata Bal, Masanori Hanada, Hikaru Kawai +1
We have calculated the free energy up to two loop to compare T^2 with T^4 in IIB matrix model. It turns out that T^2 has smaller free energy than T^4. We have also discussed the ge…
Dynamical aspects of the fuzzy CP in the large reduced model with a cubic term
Takehiro Azuma, Subrata Bal, Keiichi Nagao +1
``Fuzzy CP^2'', which is a four-dimensional fuzzy manifold extension of the well-known fuzzy analogous to the fuzzy 2-sphere (S^2), appears as a classical solution in the dimension…
Interaction between two Fuzzy Spheres
Subrata Bal, Hiroyuki Takata
We have calculated interactions between two fuzzy spheres in 3 dimension. It depends on the distance r between the spheres and the radii rho_1, rho_2. There is no force between the…
High Temperature Limit of the IIA Matrix Model
Subrata Bal, B. Sathiapalan
The high temperature limit of a system of two D-0 branes is investigated. The partition function can be expressed as a power series in (inverse temperature). The leading term i…
