Gaussian expansion analysis of a matrix model with the spontaneous breakdown of rotational symmetry
Jun Nishimura, Toshiyuki Okubo, Fumihiko Sugino
Recently the gaussian expansion method has been applied to investigate the dynamical generation of 4d space-time in the IIB matrix model, which is a conjectured nonperturbative def…
Wilson Loops and Vertex Operators in Matrix Model
Satoshi Iso, Hidenori Terachi, Hiroshi Umetsu
We systematically construct wave functions and vertex operators in the type IIB (IKKT) matrix model by expanding a supersymmetric Wilson loop operator. They form a massless multipl…
Dynamical generation of a nontrivial index on the fuzzy 2-sphere
Hajime Aoki, Satoshi Iso, Toshiharu Maeda +1
In the previous paper hep-th/0312199 we studied the 't Hooft-Polyakov (TP) monopole configuration in the U(2) gauge theory on the fuzzy 2-sphere and showed that it has a nonzero to…
On Unitary/Hermitian Duality in Matrix Models
Shun'ya Mizoguchi
Unitary 1-matrix models are shown to be exactly equivalent to hermitian 1-matrix models coupled to 2N vectors with appropriate potentials, to all orders in the 1/N expansion. This…
Gauged Linear Sigma Models for Noncompact Calabi-Yau Varieties
Tetsuji Kimura
We study gauged linear sigma models for noncompact Calabi-Yau manifolds described as a line bundle on a hypersurface in a projective space. This gauge theory has a unique phase if…
Non-Extreme Black Holes from D-branes at Angles
Satoshi Nagaoka
We construct the non-extreme solutions of non-orthogonal intersecting D-branes. The solutions reduce to non-extreme black holes upon the toroidal compactification. We clarify the r…
Perturbative dynamics of fuzzy spheres at large N
Takehiro Azuma, Keiichi Nagao, Jun Nishimura
We clarify some peculiar aspects of the perturbative expansion around a classical fuzzy-sphere solution in matrix models with a cubic term. While the effective action in the large-…
Open Semiclassical Strings and Long Defect Operators in AdS/dCFT Correspondence
Yoshiaki Susaki, Yastoshi Takayama, Kentaroh Yoshida
We consider defect composite operators in a defect superconformal field theory obtained by inserting an AdS_4 x S^2-brane in the AdS_5 x S^5 background. The one-loop dilatation ope…
Membrane Fuzzy Sphere Dynamics in Plane-Wave Matrix Model
Hyeonjoon Shin, Kentaroh Yoshida
In plane-wave matrix model, the membrane fuzzy sphere extended in the SO(3) symmetric space is allowed to have periodic motion on a sub-plane in the SO(6) symmetric space. We consi…
The continuum limit of the non-commutative lambda phi^4 model
W. Bietenholz, F. Hofheinz, J. Nishimura
We present a numerical study of the λϕ^{4} model in three Euclidean dimensions, where the two spatial coordinates are non-commutative (NC). We first show the explicit phase diagram…
Absence of a fuzzy phase in the dimensionally reduced 5d Yang-Mills-Chern-Simons model
Takehiro Azuma, Subrata Bal, Keiichi Nagao +1
We perform nonperturbative studies of the dimensionally reduced 5d Yang-Mills-Chern-Simons model, in which a four-dimensional fuzzy manifold, ``fuzzy S'', is known to exist a…
Yukawa Coupling Structure in Intersecting D-brane Models
Noriaki Kitazawa, Tatsuo Kobayashi, Nobuhito Maru +1
The structure of Yukawa coupling matrices is investigated in type IIA T^6/(Z_2 x Z_2) orientifold models with intersecting D-branes. Yukawa coupling matrices are difficult to be re…
Large N limit of SYM theories with 16 supercharges from superstrings on Dp-brane backgrounds
Masako Asano, Yasuhiro Sekino
We investigate the holographic correspondence between (p+1)-dimensional () SYM theories with 16 supercharges and superstring theories on the near-horizon limit of Dp-b…
Gravitational Corrections for Supersymmetric Gauge Theories with Flavors via Matrix Models
Hiroyuki Fuji, Shun'ya Mizoguchi
We study the gravitational corrections to the F-term in four-dimensional N=1 U(N) gauge theories with flavors, using the Dijkgraaf-Vafa theory. We derive a compact formula for the…
Open M-branes on AdS_{4/7} x S^{7/4} Revisited
Makoto Sakaguchi, Kentaroh Yoshida
We proceed further with a study of open supermembrane on the AdS_{4/7} x S^{7/4} backgrounds. Open supermembrane can have M5-brane and 9-brane as Dirichlet branes. In AdS and pp-wa…
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…
Wess-Zumino terms for AdS D-branes
Machiko Hatsuda, Kiyoshi Kamimura
We show that Wess-Zumino terms for D-p branes with p>0 in the Anti-de Sitter (AdS) space are given in terms of "left-invariant" currents on the super-AdS group or the "expanded" su…
On the relation between non-commutative field theories at theta = infinity and large N matrix field theories
Wolfgang Bietenholz, Frank Hofheinz, Jun Nishimura
It is well-known that non-commutative (NC) field theories at theta = infinity are ``equivalent'' to large N matrix field theories to all orders in perturbation theory, due to the d…

W. Bietenholz, F. Hofheinz, J. Nishimura
We present a non-perturbative study of the λϕ^{4} model in a three dimensional Euclidean space, where the two spatial coordinates are non-commutative. Our results are obtained from…
Notes on D-branes of Type IIB String on AdS_5 x S^5
Makoto Sakaguchi, Kentaroh Yoshida
We promote a study of D-branes of type IIB string on the AdS_5 x S^5 background. The possible D-branes preserving half of supersymmetries were classified up to and including the fo…
Correlators of Matrix Models on Homogeneous Spaces
Yoshihisa Kitazawa, Yastoshi Takayama, Dan Tomino
We investigate the correlators of TrA_{mu}A_{nu} in matrix models on homogeneous spaces: S^2 and S^2 x S^2. Their expectation value is a good order parameter to measure the geometr…
