Plasma Oscillations in Layered Superconductors
Very soon after publication of the famous BCS work explaining the puzzle of the superconductivity, N.N. Bogolyubov and coworkers [1] have proposed their version of the theory. One of new results they have obtained was the discovery of a collective mode an oscillation of the Cooper pair density with the energy smaller than 2∆. P.W. Anderson has indicated that this collective mode can not be foun...
متن کاملOn neutral plasma oscillations
We examine the conditions for the existence of spectrally stable neutral modes in a Vlasov-Poisson plasma and show that for stable equilibria of systems that have unbounded spatial domain, the only possible neutral modes are those with phase velocities that correspond to stationary inflection points of the equilibrium distribution function. It is seen that these neutral modes can possess positi...
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 کاملPair Creation and Plasma Oscillations *
We describe aspects of particle creation in strong fields using a quantum kinetic equation with a relaxation-time approximation to the collision term. The strong electric background field is determined by solving Maxwell’s equation in tandem with the Vlasov equation. Plasma oscillations appear as a result of feedback between the background field and the field generated by the particles produced...
