The Physics of Q-balls
Mitsuo I. Tsumagari
In this thesis we investigate the stationary properties and formation process of a class of nontopological solitons, namely Q-balls. We explore both the quantum-mechanical and clas…
Affleck-Dine dynamics, Q-ball formation and thermalisation
Mitsuo I. Tsumagari
We present both analytically and numerically the consistent analysis from the Affleck-Dine (AD) dynamics to the subsequent semiclassical evolution in both gravity-mediated and gaug…
Q-balls in flat potentials
Edmund J. Copeland, Mitsuo I. Tsumagari
We study the classical and absolute stability of Q-balls in scalar field theories with flat potentials arising in both gravity-mediated and gauge-mediated models. We show that the…
Some stationary properties of a -ball in arbitrary space dimensions
Mitsuo I. Tsumagari, Edmund J. Copeland, Paul M. Saffin
Introducing new physically motivated ansätze, we explore both analytically and numerically the classical and absolute stabilities of a single -ball in an arbitrary number of spa…
