Holographic Schwinger Effect and Chiral condensate in SYM Theory
Kazuo Ghoroku, Masafumi Ishihara
We study the instability, for the supersymmetric Yang-Mills (SYM) theories, caused by the external electric field through the imaginary part of the action of the D7 probe brane, wh…
Entanglement temperature for the excitation of SYM theory in (De)confinement phase
Kazuo Ghoroku, Masafumi Ishihara
We study the holographic supersymmetric Yang-Mills (SYM) theory, which is living in a hyperbolic space, in terms of the entanglement entropy. The theory contains a parameter ()…
Chiral Symmetry of SYM theory in hyperbolic space at finite temperature
Kazuo Ghoroku, Masafumi Ishihara, Motoi Tachibana +1
We study a holographic gauge theory living in the AdS space-time at finite temperature. The gravity dual is obtained as a solution of the type IIB superstring theory with two f…
Glueball instability and thermalization driven by dark radiation
Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura +1
We study glueballs in the holographic gauge theories living in a curved space-time. The dual bulk is obtained as a solution of the type IIB superstring theory with two parameters,…
Ad with two boundaries and holography of 4 SYM theory
Kazuo Ghoroku, Masafumi Ishihara, Akihiro Nakamura
According to the AdS/CFT correspondence, the supersymmetric Yang-Mills (SYM) theory is studied through its gravity dual whose configuration has two boundaries at the o…
Tensor Network and Black Hole
Hiroaki Matsueda, Masafumi Ishihara, Yoichiro Hashizume
A tensor network formalism of thermofield dynamics is introduced. The formalism relates the original Hilbert space with its tilde space by a product of two copies of a tensor netwo…
