Abstract: Magnetic fusion devices operate at regimes characterized by extremely high temperatures and low densities, for which the charged particles motion is well described by classical mechanics. This is not true, however, for solid-state metallic objects: their density approaches 1028 m−3, so that the average interparticle distance is shorter than the de Broglie wavelength, which characterizes the spread of the electron wave function. Under these conditions, the conduction electrons behave as a true quantum plasma even at room temperature. Here, we shall illustrate the impact of quantum phenomena on the electron dynamics in metallic objects of nanometric size, particularly thin metallic films excited by short laser pulses. Further, we will discuss more recent results on regimes that involve spin and relativistic effects.

Quantum kinetic theory of plasmas
Gert Brodin,Jens Zamanian +1 more
TL;DR: In this paper , the quantum kinetic theory is extended to cover Zitterbewegung and electron-positron pair creation, and the so-called Dirac-Heisenberg-Wigner (DHW) formalism, which is a fully quantum relativistic theory.

Coexistence of negative and positive polarity electrostatic solitary waves in ultradense relativistic negative-ion-beam permeated plasmas
I. S. Elkamash,Ioannis Kourakis +1 more
TL;DR: In this paper, the criteria for occurrence and the dynamical features of electrostatic solitary waves in a homogeneous, unmagnetized ultradense plasma penetrated by a negative ion beam are investigated, relying on a quantum hydrodynamic model.
Landau damping of electrostatic waves in arbitrarily degenerate quantum plasmas
TL;DR: In this paper, a systematic study of the dispersion relation for linear electrostatic waves in an arbitrarily degenerate quantum electron plasma was carried out and it was shown that the real part of the frequency ωr grows linearly with k and scales with μ, only because of the scaling of the Fermi energy.

Electron dynamics in plasmons.
TL;DR: The Particle-in-Cell (PIC) method for plasmons provides a mechanical, single-particle picture of plasmon resonances by tracking in time the movement of all the individual conduction electrons as mentioned in this paper.

On the quantum correction for thermodynamic equilibrium
TL;DR: In this article, the Boltzmann formula for lower temperatures has been developed for a correction term, which can be developed into a power series of h. The formula is developed for this correction by means of a probability function and the result discussed.

Nobel Lecture: Electronic structure of matter-wave functions and density functionals
TL;DR: In this article, an alternative approach to the theory of electronic struc- ture, in which the electron density distribution n(r), rather than the many-electron wave function, plays a central role, is presented.
