Correlation between momentum modes and winding modes in Brandenberger-Vafa's string cosmological model
Kenji Hotta, Keiji Kikkawa, Hiroshi Kunitomo
Brandenberger and Vafa have proposed the string cosmological model based on T-duality. In this model, they took the toroidal target space and introduced the new position \tilde{x}…

T-Duality and Time development of a (2+1)-Dimensional String Universe
Kenji Hotta, Keiji Kikkawa, Michihiko Sakamoto
The time development of a model of (2+1)-dimensional torus universe is studied based on background field equations which follow from a string theory. The metrics in various cases a…

Dynamical Gauge Field induced by the Berry Phase Mechanism
Keiji Kikkawa, Humitaka Tamura
Some part of the local gauge symmetries in the low energy region, say, lower than GUT or the Planck energy can be an induced symmetry describable with the holonomy fields associate…
