Spectrum-Generating Algebra for Charged Superstrings in Background Gauge Fields
Akira Kokado, Gaku Konisi, Takesi Saito
The spectrum-generating algebra (SGA) for charged superstrings placed in constant background magnetic fields is constructed. Contrary to the neutral string this algebra is characte…
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.…
Scalar-Tensor Theory of Gravity on Geometry
Akira Kokado, Gaku Konisi, Takesi Saito +1
In the Brans-Dicke(BD) theory on geometry the geometrical meaning of the torsion is clarified. The BD theory on is rederived by taking into…
