On the shape of a D-brane bound state and its topology change
Tatsuo Azeyanagi, Masanori Hanada, Tomoyoshi Hirata +1
As is well known, coordinates of D-branes are described by NxN matrices. From generic non-commuting matrices, it is difficult to extract physics, for example, the shape of the dist…
On Matrix Model Formulations of Noncommutative Yang-Mills Theories
Tatsuo Azeyanagi, Masanori Hanada, Tomoyoshi Hirata
We study stability of noncommutative spaces in matrix models and discuss the continuum limit which leads to noncommutative Yang-Mills theories (NCYM). It turns out that most of non…
Decaying D-branes and Moving Mirrors
Tomoyoshi Hirata, Shinji Mukohyama, Tadashi Takayanagi
We present an exact time-dependent solution to the effective D-brane world-volume theory which describes an inhomogeneous decay of a brane-antibrane system. We compute the quantum…
Higher Derivative Correction to the Hawking Flux via Trace Anomaly
Akihide Shirasaka, Tomoyoshi Hirata
In this paper we derive Hawking radiation of black holes with higher derivative corrections by the method of trace anomaly. Firstly we derive Hawking radiation for general spherica…
New inequality for Wilson loops from AdS/CFT
Tomoyoshi Hirata
The strong subadditivity is the most important inequality which entanglement entropy satisfies. Based on the AdS/CFT conjecture, entanglement entropy in CFT is equal to the area of…
Phase structure of twisted Eguchi-Kawai model
Tatsuo Azeyanagi, Masanori Hanada, Tomoyoshi Hirata +1
Twisted Eguchi-Kawai model is a useful tool for studying the large-N gauge theory. It can also provide a nonperturbative formulation of the gauge theory on noncommutative spaces. R…
