Chiral rings, anomalies and loop equations in N=1* gauge theories
Taichi Itoh
We examine the equivalence between the Konishi anomaly equations and the matrix model loop equations in N=1* gauge theories, the mass deformation of N=4 supersymmetric Yang-Mills.…
The 11-dimensional Metric for AdS/CFT RG Flows with Common SU(3) Invariance
Changhyun Ahn, Taichi Itoh
The compact 7-manifold arising in the compactification of 11-dimensional supergravity is described by the metric encoded in the vacuum expectation values(vevs) in d=4, N=8 gauged s…
A note on singular D-branes in group manifolds
Taichi Itoh, Sang-Jin Sin
After reviewing D-branes as conjugacy classes and various charge quantizations (modulo ) in WZW model, we develop the classification and systematic construction of all possible…
Classification and Quantum Moduli Space of D-branes in Group Manifolds
Taichi Itoh, Sang-Jin Sin
We study the classification of D-branes in all compact Lie groups including non-simply-laced ones. We also discuss the global structure of the quantum moduli space of the D-branes.…
An N=1 Supersymmetric G_2-invariant Flow in M-theory
Changhyun Ahn, Taichi Itoh
It was found that deformation of S^7 gives rise to renormalization group(RG) flow from N=8, SO(8)-invariant UV fixed point to N=1, G_2-invariant IR fixed point in four-dimensional…
Dielectric-branes in Non-supersymmetric SO(3)-invariant Perturbation of Three-dimensional N=8 Yang-Mills Theory
Changhyun Ahn, Taichi Itoh
We study non-supersymmetric SO(3)-invariant deformations of d=3, N=8 super Yang-Mills theory and their type IIA string theory dual. By adding both gaugino mass and scalar mass, die…
Duality and Enhanced Gauge Symmetry in 2+1 Dimensions
Taichi Itoh, Phillial Oh, Cheol Ryou
We investigate the enlarged CP(N) model in 2+1 dimensions. This is a hybrid of two CP(N) models coupled with each other in a dual symmetric fashion, and it exhibits the gauge symme…
Gauge Symmetry Enhancement and Radiatively Induced Mass in the Large N Nonlinear Sigma Model
Taichi Itoh, Phillial Oh, Cheol Ryou
We consider a hybrid of nonlinear sigma models in which two complex projective spaces are coupled with each other under a duality. We study the large N effective action in 1+1 dime…
Higher Derivative CP(N) Model and Quantization of the Induced Chern-Simons Term
Taichi Itoh, Phillial Oh
We consider higher derivative CP(N) model in 2+1 dimensions with the Wess-Zumino-Witten term and the topological current density squared term. We quantize the theory by using the a…
Large N Limit of Higher Derivative Extended CP(N) Model
Taichi Itoh, Phillial Oh
We construct a fourth-order derivative CP(N) model in 1+1 dimensions by incorporating the topological charge density squared term into the Lagrangian. We quantize the theory by ref…
Dynamical Generation of Fermion Mass and Magnetic Field in Three-Dimensional QED with Chern-Simons Term
Taichi Itoh, Hiroshi Kato
We study dynamical symmetry breaking in three-dimensional QED with a Chern-Simons (CS) term, considering the screening effect of flavor fermions. We find a new phase of the vac…
Charge Condensation in QED with a Chern-Simons Term
Taichi Itoh, Toshiro Sato
Introducing a chemical potential in the functional method, we construct the effective action of QED with a Chern-Simons term. We examine a possibility that charge condensation…

Taichi Itoh, Yoonbai Kim, Masaki Sugiura +1
We reformulate the Thirring model in dimensions as a gauge theory by introducing hidden local symmetry (HLS) and study the dynamical mass generation of t…
