Abstract:
The screening of local electrostatic perturbation by indirect excitons has been investigated. It has been shown
that the linear screening is dielectric, and the effective dielectric constant may be large in the case of high
degeneracy of the Bose gas of excitons. The emergence of a condensate significantly changes the behavior of
the perturbation potential at infinity, leading to power-law asymptotic behavior with large exponents. In the
nonlinear regime, the screened potential is saturated with an unlimited increase in the initial perturbation.
