Description
A theoretical model for a stable spherically symmetric plasma
structure based on radial oscillations of electrons in plasma is
proposed. We study electrons oscillations in both classical and
quantum approaches. Within the quantum approach we get an approximate
solution on the nonlinear Schrodinger equation and the dispersion
relation for the spherically symmetric oscillation. The numerical
simulation of the exact Schrodinger equation containing the nonlinear
terms is presented, showing an agreement with the approximate
analytical solution. Then we calculate attractive effective potential
between two electrons participating in radial oscillations and show
that electrons can form a bound state. We discuss the possibility that
the proposed model can be implemented in nature as a rare atmospheric
electricity phenomenon call a ''ball lightning'' (BL). The observed
characteristics of BL are summarized. We also briefly list the
previous BL models. Finally we analyze a possibility how long lived
spherically symmetric plasma structures can be generated in a
laboratory.
