Note on Gauge Theory on Fuzzy Supersphere

Satoshi Iso, Hiroshi Umetsu

We construct a supermatrix model whose classical background gives two-dimensional noncommutative supersphere. Quantum fluctuations around it give the supersymmetric gauge theories…

Ginsparg-Wilson Relation and 't Hooft-Polyakov Monopole on Fuzzy 2-Sphere

Hajime Aoki, Satoshi Iso, Keiichi Nagao

We investigate several properties of Ginsparg-Wilson fermion on fuzzy 2-sphere. We first examine chiral anomaly up to the second order of the gauge field and show that it is indeed…

Supersymmetric Radius Stabilization in Warped Extra Dimensions

Nobuhito Maru, Nobuchika Okada

We propose a simple model of extra-dimensional radius stabilization in a supersymmetric Randall-Sundrum model. In our model, we introduce only a bulk hypermultiplet and source term…

Dirichlet Branes of the Covariant Open Supermembrane in AdS_4 x S^7 and AdS_7 x S^4

Makoto Sakaguchi, Kentaroh Yoshida

We discuss an open supermembrane theory in the AdS_4 x S^7 and AdS_7 x S^4 backgrounds. The possible Dirichlet branes of an open supermembrane are classified by analyzing the covar…

Testing the Gaussian expansion method in exactly solvable matrix models

Jun Nishimura, Toshiyuki Okubo, Fumihiko Sugino

The Gaussian expansion has been developed since early 80s as a powerful analytical method, which enables nonperturbative studies of various systems using `perturbative' calculation…

D-branes of Covariant AdS Superstrings

Makoto Sakaguchi, Kentaroh Yoshida

We consider D-branes of open superstrings in the AdS_5 x S^5 background. The possible configurations of D-branes preserving half of supersymmetries are classified by analyzing the…

Closed String Field Theory with Dynamical D-brane

Tsuguhiko Asakawa, Shinpei Kobayashi, So Matsuura

We consider a closed string field theory with an arbitrary matter current as a source of the closed string field. We find that the source must satisfy a constraint equation as a co…

Numerical results on the Non-commutative λϕ^4 Model

W. Bietenholz, F. Hofheinz, J. Nishimura

The UV/IR mixing in the λϕ^4 model on a non-commutative (NC) space leads to new predictions in perturbation theory, including Hartree-Fock type approximations. Among them there is…

Matrix Model and Ginsparg-Wilson Relation

Keiichi Nagao

We discuss that the Ginsparg-Wilson relation, which has the key role in the recent development of constructing lattice chiral gauge theory, can play an important role to define chi…

Remarks on Phase Transitions in Matrix Models and N=1 Supersymmetric Gauge Theory

Hiroyuki Fuji, Shun'ya Mizoguchi

A hermitian one-matrix model with an even quartic potential exhibits a third-order phase transition when the cuts of the matrix model curve coalesce. We use the known solutions of…

M-theory on a Time-dependent Plane-wave

Makoto Sakaguchi, Kentaroh Yoshida

We propose a matrix model on a homogeneous plane-wave background with 20 supersymmetries. This background is anti-Mach type and is equivalent to the time-dependent background. We s…

One-Loop Flatness of Membrane Fuzzy Sphere Interaction in Plane-Wave Matrix Model

Hyeonjoon Shin, Kentaroh Yoshida

In the plane-wave matrix model, the background configuration of two membrane fuzzy spheres, one of which rotates around the other one in the SO(6) symmetric space, is allowed as a…

Background Field Method in Stochastic Quantization of N = 1 Supersymmetric Yang-Mills Theory

Naohito Nakazawa

In the previous works, we proposed the stochastic quantization method (SQM) approach to N=1 supersymmetric Yang-Mills theory (SSYM). In four dimensions, in particular, we obtained…

Conformal boundary states in SU(2)_1/G

A. Yamaguchi

We construct boundary states in a particular c=1 conformal field theory, the SU(2)_1/G orbifold with G a binary finite subgroup of SU(2). These states preserve the conformal symmet…

PP-Wave Holography for Dp-Brane Backgrounds

Masako Asano, Yasuhiro Sekino, Tamiaki Yoneya

As an extension of the so-called BMN conjecture, we investigate the plane-wave limit for possible holographic connection between bulk string theories in non-conformal backgrounds o…

Membrane and Noncommutativity

Rabin Banerjee, Biswajit Chakraborty, Kuldeep Kumar

We analyse the dynamics of an open membrane, both for the free case and when it is coupled to a background three-form, whose boundary is attached to -branes. The role of boundar…
