Atomic Structure in Black Hole
Yukinori Nagatani
We propose that any black hole has atomic structure in its inside and has no horizon as a model of black holes. Our proposal is founded on a mean field approximation of gravity. Th…
Spontaneous Partial Breaking of N=2 Supersymmetry and the U(N) Gauge Model
Kazuhito Fujiwara, Hiroshi Itoyama, Makoto Sakaguchi
We briefly review the properties of the N=2 U(N) gauge model with/without matters. On the vacua, N=2 supersymmetry and the gauge symmetry are spontaneously broken to N=1 and a prod…
Noncommutative M-branes from Covariant Open Supermembranes
Makoto Sakaguchi, Kentaroh Yoshida
We discuss an open supermembrane in the presence of a constant three-form. The boundary conditions to ensure the kappa-invariance of the action lead to possible Dirichlet branes. I…
A Holographic Framework for Eternal Inflation
Ben Freivogel, Yasuhiro Sekino, Leonard Susskind +1
In this paper we provide some circumstantial evidence for a holographic duality between bubble nucleation in an eternally inflating universe and a Euclidean conformal field theory.…
Dirac Sea and Hole Theory for Bosons II -- Renormalization Approach --
Yoshinobu Habara, Yukinori Nagatani, Holger B. Nielsen +1
In bosonic formulation of the negative energy sea, so called Dirac sea presented in the preceding paper [arXiv:hep-th/0603242], one of the crucial points is how to construct a posi…
Anomalies, Hawking Radiations and Regularity in Rotating Black Holes
Satoshi Iso, Hiroshi Umetsu, Frank Wilczek
This is an extended version of our previous letter hep-th/0602146. In this paper we consider rotating black holes and show that the flux of Hawking radiation can be determined by a…
