Radiation from an accelerated quark via AdS/CFT
Kengo Maeda, Takashi Okamura
In this paper we investigate radiation by an accelerated quark in a strongly coupled gauge theory via AdS/CFT correspondence. According to AdS/CFT dictionary, we can read off energ…
Comment on "Viscous hydrodynamics relaxation time from AdS/CFT correspondence"
Makoto Natsuume, Takashi Okamura
This is a comment to hep-th/0703243. The paper determined the relaxation time tau_pi of the shear viscous stress for the N=4 SYM from AdS/CFT correspondence. The purpose of this co…
Hall effect in Noncommutative spaces
Akira Kokado, Takashi Okamura, Takesi Saito
In order to investigate whether space coordinates are intrinsically noncommutative, we make use of the Hall effect on the two-dimensional plane. We calculate the Hall conductivity…
Noncommutative Hall Effect
Akira Kokado, Takashi Okamura, Takesi Saito
When coordinates are noncommutative, the Hall effect is reinvestigated. The Hall conductivity is expressed with noncommutative parameters, so that in the commutative limit it tends…
Wigner's Formulation of Noncommutative Quantum Mechanics
Akira Kokado, Takashi Okamura, Takesi Saito
When we have noncommutativity among coordinates (or conjugate momenta), we consider Wigner's formulation of quantum mechanics, including a new derivation of path integral formula.…
