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…
Heat kernel coefficients for compact fuzzy spaces
Naoki Sasakura
I discuss the trace of a heat kernel Tr[e^(-tA)] for compact fuzzy spaces. In continuum theory its asymptotic expansion for t -> +0 provides geometric quantities, and therefore may…
Construction of Supergravity Backgrounds with a Dilaton Field
Noriko Nakayama, Katsuyuki Sugiyama
A new class of non-compact Kahler backgrounds accompanied by a non-constant dilaton field is constructed as a supergravity solution. It is interpreted as a complex line bundle over…
Free Fermion and Seiberg-Witten Differential in Random Plane Partitions
Takashi Maeda, Toshio Nakatsu, Kanehisa Takasaki +1
A model of random plane partitions which describes five-dimensional supersymmetric SU(N) Yang-Mills is studied. We compute the wave functions of fermions in this st…
Five-Dimensional Supersymmetric Yang-Mills Theories and Random Plane Partitions
Takashi Maeda, Toshio Nakatsu, Kanehisa Takasaki +1
Five-dimensional supersymmetric Yang-Mills theories are investigated from the viewpoint of random plane partitions. It is shown that random plane partitions are fac…
Direct derivation of the Veneziano-Yankielowicz superpotential from matrix model
Hikaru Kawai, Tsunehide Kuroki, Takeshi Morita +1
We derive the Veneziano-Yankielowicz superpotential directly from the matrix model by fixing the measure precisely. The essential requirement here is that the effective superpotent…
Reduced qKZ equation and correlation functions of the XXZ model
H. Boos, M. Jimbo, T. Miwa +2
Correlation functions of the XXZ model in the massive and massless regimes are known to satisfy a system of linear equations. The main relations among them are the difference equat…
Partition function for a singular background
J. J. Mckenzie-Smith, Wade Naylor
We present a method for evaluating the partition function in a varying external field. Specifically, we look at the case of a non-interacting, charged, massive scalar field at fini…
Low energy hadron physics in holographic QCD
Tadakatsu Sakai, Shigeki Sugimoto
We present a holographic dual of four-dimensional, large N_c QCD with massless flavors. This model is constructed by placing N_f probe D8-branes into a D4 background, where supersy…
Universality of Nonperturbative Effect in Type 0 String Theory
Hikaru Kawai, Tsunehide Kuroki, Yoshinori Matsuo
We derive the nonperturbative effect in type 0B string theory, which is defined by taking the double scaling limit of a one-matrix model with a two-cut eigenvalue distribution. How…
Partial Gauge Symmetry Breaking via Bare Mass
Naoyuki Haba, Kazunori Takenaga, Toshifumi Yamashita
We study gauge symmetry breaking patterns in supersymmetric gauge models defined on . Instead of utilizing the Scherk-Schwarz mechanism, supersymmetry is broken by b…
Dirac Sea for Bosons II -- Study of the Naive Vacuum Theory for the Playground World Prior to Filling the Negative Energy Sea --
Holger B. Nielsen, Masao Ninomiya
We use our previous idea, in which at first we perform a naive second quantization of both negative and positive energy for the Klein-Gordon equation analogous to the unfilled Dira…
Dirac Sea for Bosons I -- Formulation of Negative Energy Sea for Bosons
Holger B. Nielsen, Masao Ninomiya
It is proposed to make formulation of second quantizing a bosonic theory by generalizing the method of filling the Dirac negative energy sea for fermions. We interpret that the cor…

Naoyuki Haba, Kazunori Takenaga, Toshifumi Yamashita
We study an supersymmetric Yang-Mills theory defined on . The vacuum expectation values for adjoint scalar field in vector multiplet, though important,…
Equilibrium Positions, Shape Invariance and Askey-Wilson Polynomials
S. Odake, R. Sasaki
We show that the equilibrium positions of the Ruijsenaars-Schneider-van Diejen systems with the trigonometric potential are given by the zeros of the Askey-Wilson polynomials with…
Massless Boundary Sine-Gordon Model Coupled to External Fields
H. Kogetsu, S. Teraguchi
We investigate a generalization of the massless boundary sine-Gordon model with conformal invariance, which has been used to describe an array of D-branes (or rolling tachyon). We…

W. -L. Yang, R. Sasaki, Y. -Z. Zhang
The elliptic Gaudin model with integrable boundaries specified by generic non-diagonal K-matrices with free boundary parameters is studied. The commuting families of Ga…
Shape Invariant Potentials in "Discrete Quantum Mechanics"
S. Odake, R. Sasaki
Shape invariance is an important ingredient of many exactly solvable quantum mechanics. Several examples of shape invariant ``discrete quantum mechanical systems" are introduced an…
