Vacuum polarization near boundaries

چکیده
We study the effect of boundary conditions on vacuum polarization for charged scalar fields in two space-time dimensions. find that both Dirichlet and Neumann lead to screening. In case, charge density vanishes at boundary, whereas it attains its maximum there conditions. At a critical field strength, diverges conditions, an due instability lowest energy mode presence external field.

Vacuum Energy Density near Fluctuating Boundaries
The imposition of boundary conditions upon a quantized field can lead to singular energy densities on the boundary. We treat the boundaries as quantum mechanical objects with a nonzero position uncertainty, and show that the singular energy density is removed. This treatment also resolves a long standing paradox concerning the total energy of the minimally coupled and conformally coupled scalar...
متن کاملVacuum polarization and plasma oscillations
We evidence the existence of plasma oscillations of electrons-positron pairs created by the vacuum polarization in an uniform electric field with E . Ec. Our general treatment, encompassing also the traditional, well studied case of E > Ec, shows the existence in both cases of a maximum Lorentz factor acquired by electrons and positrons and allows determination of the a maximal length of oscill...
متن کاملBraneworld dynamics with vacuum polarization
We investigate the cosmological dynamics of a brane Universe when quantum corrections from vacuum polarization are taken into account. New vacuum de Sitter points existing on Randall-Sundrum brane are described. We show also that quantum correction can destroy the DGP de Sitter solution on induced gravity brane. † Electronic mail: [email protected] ‡ Electronic mail: [email protected] Investig...
متن کاملParton Production Via Vacuum Polarization
For high matter and/or energy densities a deconfined state of matter, the so-called quark-gluon plasma (QGP) has been predicted to exist [1]. Its production is expected for ultrarelativistic heavy-ion collisions (URHIC) at RHIC and LHC. No direct signatures for its presence are experimentally accessible. In order to be able to decide which indirect ones could be available, detailed knowledge ab...
متن کاملGravitational vacuum polarization IV: Energy conditions in the Unruh vacuum
Building on a series of earlier papers [gr-qc/9604007,9604008,9604009], I investigate the various point-wise and averaged energy conditions in the Unruh vacuum. I consider the quantum stress-energy tensor corresponding to a conformally coupled massless scalar field, work in the test-field limit, restrict attention to the Schwarzschild geometry, and invoke a mixture of analytical and numerical t...
