Duality in Landau-Zener-Stueckelberg potential curve crossing
Kazuo Fujikawa, Hiroshi Suzuki
It is pointed out that there exists an interesting strong and weak duality in the Landau-Zener-Stueckelberg potential curve crossing. A reliable perturbation theory can thus be for…
SO(9,1) invariant matrix formulation of supermembrane
Kazuo Fujikawa, Kazumi Okuyama
An invariant formulation of an 11-dimensional supermembrane is presented by combining an invariant treatment of reparametrization symmetry with an in…
BRST gauge fixing and the algebra of global supersymmetry
Kazuo Fujikawa, Kazumi Okuyama
A global supersymmetry (SUSY) in supersymmetric gauge theory is generally broken by gauge fixing. A prescription to extract physical information from such SUSY algebra broken by ga…
An extended q-deformed su(2) algebra and the Bloch electron problem
Kazuo Fujikawa, Harunobu Kubo
It is shown that an extended q-deformed algebra with an extra (``Schwinger '') term can describe Bloch electrons in a uniform magnetic field with an additional periodic pot…
On a Lorentz covariant matrix regularization of membrane theories
Kazuo Fujikawa, Kazumi Okuyama
A Lorentz covariant matrix regularization of membrane thories is studied.It is shown that the action for a bosonic membrane can be defined by matrix regularization in a Lorentz cov…
Duality in potential curve crossing: Application to quantum coherence
Kazuo Fujikawa, Hiroshi Suzuki
A field dependent gauge transformation connects between the adiabatic and diabatic pictures in the (Landau-Zener-Stueckelberg) potential curve crossing problem. It is point…
