Analysis for Lorentzian conformal field theories through sine-square deformation
Xun Liu, Tsukasa Tada
We reexamine two-dimensional Lorentzian conformal field theory using the formalism previously developed in a study of sine-square deformation of Euclidean conformal field theory. W…
Time development of conformal field theories associated with and operators
Tsukasa Tada
In this study, we examined consequences of unconventional time development of two-dimensional conformal field theory induced by the and operators, employing the fo…
Conformal Quantum Mechanics and Sine-Square Deformation
Tsukasa Tada
We revisit conformal quantum mechanics (CQM) from the perspective of sine-square deformation (SSD) and the entanglement Hamiltonian. The operators that correspond to SSD and the en…
Dipolar quantization and the infinite circumference limit of two-dimensional conformal field theories
Nobuyuki Ishibashi, Tsukasa Tada
Elaborating on our previous presentation, where the term {\it dipolar quantization} was introduced, we argue here that adopting $L_0-(L_1+L_{-1})/2+{\bar L}_0-({\bar L}_1+{\bar L}_…
Infinite circumference limit of conformal field theory
Nobuyuki Ishibashi, Tsukasa Tada
We argue that an infinite circumference limit can be obtained in 2-dimensional conformal field theory by adopting as a Hamiltonian instead of . The theory…
Sine-Square Deformation and its Relevance to String Theory
Tsukasa Tada
Sine-square deformation, a recently found modulation of the coupling strength in certain statistical models, is discussed in the context of two-dimensional conformal field theories…
Matrix model criticality and resonant tunneling
Tsukasa Tada
We suggest that the Hermitian matrix models with resonant tunneling may exhibit novel criticality. Some features of the proposed criticality are explored. In particular, we argue t…
Note on a fermionic solution of the matrix model and noncommutative superspace
Yuuichirou Shibusa, Tsukasa Tada
We present a new fermionic solution of the supersymmetric matrix model. The solution satisfies the commutation and anticommutation relations for noncommutative superspace. Therefor…
Noncommutative Yang-Mills in IIB Matrix Model
H. Aoki, N. Ishibashi, S. Iso +3
We show that twisted reduced models can be interpreted as noncommutative Yang-Mills theory. Based upon this correspondence, we obtain noncommutative Yang-Mills theory with D-brane…
IIB Matrix Model
H. Aoki, S. Iso, H. Kawai +3
We review our proposal for a constructive definition of superstring, type IIB matrix model. The IIB matrix model is a manifestly covariant model for space-time and matter which pos…
On the supersymmetric formulation of Unitary Matrix Model of type IIB
Tsukasa Tada, Asato Tsuchiya
We propose a unitary matrix formulation of type IIB matrix model. One-loop effective action of the model exhibits supersymmetry for BPS background in the large N limit.
Space-Time Structures from IIB Matrix Model
H. Aoki, S. Iso, H. Kawai +2
We derive a long distance effective action for space-time coordinates from a IIB matrix model. It provides us an effective tool to study the structures of space-time. We prove the…
Entropy of Four-Dimensional Rotating BPS-Dyons
Jerome P. Gauntlett, Tsukasa Tada
The known BPS dyon black hole solutions of the N=4 heterotic string in four dimensions with non-zero angular momentum all have naked singularities. We show that it is possible to m…
An Extreme Black Hole with Electric Dipole Moment
Gary T. Horowitz, Tsukasa Tada
We construct a new extreme black hole solution in toroidally compactified heterotic string theory. The black hole saturates the Bogomol'nyi bound, has zero angular momentum, but no…
Consequence of Hawking radiation from 2d dilaton black holes
Tsukasa Tada, Shozo Uehara
We investigate the CGHS model through numerical calculation. The behavior of the mass function, which we introduced in our previous work as a ``local mass'', is examined. We found…
On the Mass of Two Dimensional Quantum Black Hole
Tsukasa TADA, Shozo UEHARA
For the two dimensional dilaton-coupled quantum gravity model, we give the local black hole mass, which is an analogue of what was first introduced by Fischler, Morgan and Polchins…
