Fundamental Forces and Scalar Field Dynamics in the Early Universe
Alexander Kusenko, Volodymyr Takhistov, Masaki Yamada +1
Scalar weak gravity conjectures (SWGCs) attempt to pinpoint the ranges of couplings consistent with a fundamental theory of all interactions. We identify a generic dynamical conseq…
Sufficient conditions for the existence of Q-balls in gauge theories
Alexander Kusenko, Mikhail Shaposhnikov, P. G. Tinyakov
We formulate a set of simple sufficient conditions for the existence of Q-balls in gauge theories.
Small Q balls
Alexander Kusenko
We develop an adequate description of non-topological solitons with a small charge, for which the thin-wall approximation is not valid. There is no classical lower limit on the cha…
Vacuum decay and internal symmetries
Alexander Kusenko, Kimyeong Lee, Erick J. Weinberg
We study the effects of internal symmetries on the decay by bubble nucleation of a metastable false vacuum. The zero modes about the bounce solution that are associated with the br…
