复Signum-Gordon模型中的紧Q球
Compact Q-balls in the complex signum-Gordon model
摘要:
讨论了d维空间中复Signum-Gordon模型中的Q球,其中d= 1,2,3. Q球具有严格有限的半径。它们的总能量是守恒U(1)荷的类幂函数,其指数等于(d+2)/(d+3)。在d=1和d=3的情况下,给出了显式解析解。
英文摘要:
We discuss Q-balls in the complex signum-Gordon model in d-dimensional space for d=1,2,3. The Q-balls have strictly finite radius. Their total energy is a power-like function of the conserved U(1) charge with the exponent equal to (d+2)/(d+3). In the cases d=1 and d=3 explicit analytic solutions are presented.
