Description
A model describing a fermionic particle or Q-ball in a superfluid vacuum is studied numerically. We show that it is a nonlinear double-eigenvalue problem, which thus requires a special treatment. The essential equations to solve are four nonlinear differential equations involving the spinor, electrostatic, and the logarithmically nonlinear scalar field which effectively describes background superfluid in a low-energy regime. The solution is derived in a recursive way, a detailed example demonstrating this process is presented. Among other values, self-energy and total charge of the object are numerically derived. The main conclusion is that our model is free of field singularities, its self-energy is finite and its electric field obeys the Coulomb asymptotics.
