Weyl Invariant Spacetime
Yutaka Hosotani
A new class of Weyl invariant backgrounds are presented in terms of the metric and the anti-symmetric Kalb-Ramond fields . The ten-dimensional spacetime is a produ…
Solitons in the false vacuum
Yutaka Hosotani
When a potential for a scalar field has two local minima, there arises structure of spherical shells due to gravitational interactions.
Complex Monopoles in the Path Integral
Y. Hosotani, B. Tekin, K. Saririan
Complex monopole configurations dominate in the path integral in the Georgi-Glashow-Chern-Simons model and disorder the Higgs vacuum. No cancellation is expected among Gribov copie…
Complex Monopoles and Gribov Copies
Y. Hosotani, K. Saririan, B. Tekin
Complex monopole solutions exist in the three dimensional Georgi-Glashow model with the Chern-Simons term. They dominate the path integral and disorder the Higgs vacuum. Gribov cop…
Complex Monopoles in YM + Chern-Simons Theory in 3 Dimensions
Bayram Tekin, Kamran Saririan, Yutaka Hosotani
In this talk, we give a brief discussion of complex monopole solutions in the three dimensional Georgi-Glashow model with a Chern-Simons term. We find that there exist complex mono…
Chiral Dynamics in Weak, Intermediate, and Strong Coupling QED in Two Dimensions
Yutaka Hosotani
N flavor QED in two dimensions is reduced to a quantum mechanics problem with N degrees of freedom for which the potential is determined by the ground state of the problem itself.…
