Massive Rigid String Model and its Supersymmetric Extension
Kiyoshi Kamimura, Daisuke Shiseki
We discuss a rigid string model proposed by Casalbuoni and Longhi. Constraints for the massive states are solved to find the physical states and the mass spectrum. We also find its…
Anisotropic harmonic oscillator, non-commutative Landau problem and exotic Newton-Hooke symmetry
Pedro D. Alvarez, Joaquim Gomis, Kiyoshi Kamimura +1
We investigate the planar anisotropic harmonic oscillator with explicit rotational symmetry as a particle model with non-commutative coordinates. It includes the exotic Newton-Hook…
Projective Coordinates and Projective Space Limit
Machiko Hatsuda, Kiyoshi Kamimura
The "projective lightcone limit" has been proposed as an alternative holographic dual of an AdS space. It is a new type of group contraction for a coset G/H preserving the isometry…
Gauge transformations and symmetries of integrable systems
Takeshi Fukuyama, Kiyoshi Kamimura, Sasa Kresić-Jurić +1
We analyze several integrable systems in zero-curvature form within the framework of invariant gauge theory. In the Drienfeld-Sokolov gauge we derive a two-parameter fam…
