Baryon as Impurity for Phase Transition in String Landscape
Aya Kasai, Yuichiro Nakai, Yutaka Ookouchi
We consider a decay of a false vacuum in flux compactifications of type IIB string theory and study a catalytic effect for a phase transition induced by a new type of impurities. W…
Gravitational Correction to Fuzzy String in Metastable Brane Configuration
Aya Kasai, Yutaka Ookouchi
We study dynamics of a cosmic string in a metastable brane configuration in Type IIA string theory. We first discuss a decay process of the cosmic string via a fuzzy brane (equival…
Decay of False Vacuum via Fuzzy Monopole in String Theory
Aya Kasai, Yutaka Ookouchi
We investigate dielectric branes in false vacua in Type IIB string theory. The dielectric branes are supported against collapsing by lower energy vacua inside spherical or tube-lik…
Bosonization in the path integral formulation
Kazuo Fujikawa, Hiroshi Suzuki
We establish the direct on-shell bosonization and in path integral formulation by deriving the off-shell r…
