Vacuum structure of a scalar field on a torus with uniform magnetic flux
Mayumi Akamatsu, Hiroki Imai, Makoto Sakamoto +1
We investigate the vacuum expectation value of a complex scalar field on a two-dimensional torus with quantized magnetic flux . A characteristic feature of this system is the em…
Topological Terms in String Theory on Orbifolds
M. Sakamoto, M. Tachibana
We study toroidal orbifold models with topologically invariant terms in the path integral formalism and give physical interpretations of the terms from an operator formalism point…
Toroidal Orbifold Models with a Wess-Zumino Term
J. O. Madsen, M. Sakamoto
Closed bosonic string theory on toroidal orbifolds is studied in a Lagrangian path integral formulation. It is shown that a level one twisted WZW action whose field value is restri…
String Theories on the Asymmetric Orbifolds with Twist-Untwist Intertwining Currents
Y. Imamura, M. Sakamoto, T. Sasada +1
We give various examples of asymmetric orbifold models to possess intertwining currents which convert untwisted string states to twisted ones, and vice versa, and see that such asy…
