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 $10^{28} \rm m^{-3}$, 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.

Possible increased critical temperature Tc in anisotropic bosonic gases.
TL;DR: A finite thermal anisotropy, if maintained for times longer than thermal relaxation times, may have a positive effect on the critical temperature in Bose-Einstein condensation of a dilute boson gas not in thermal equilibrium or quasi-particle fermi fluid consisting of spin-compensated electron pairs as discussed by the authors.
Short-scale quantum kinetic theory including spin–orbit interactions
TL;DR: In this paper, a quantum kinetic theory for spin-1/2 particles, including the spin-orbit interaction, was presented, retaining particle dispersive effects to all orders in ℏ, based on a gauge invariant Wigner transfo...
Spin effect on propagation of surface waves in a magneto-active quantum plasma
Abstract: The linear response theory has been employed to investigate the effect of electrons' intrinsic spin on the propagation of surface waves in a magneto‐active quantum plasma half‐space. Using fluid Maxwell equations, we obtained two coupled differential equations for perturbed magnetic field and density. The method of characteristic equation is used to find the exact solution to the system of coupled differential equations and exact dispersion relation for the quantum surface waves. The dispersion relation is numerically analysed to study spin and magnetization effects, and it is shown that both of these effects increase group velocity of surface waves, while spin effect reduces phase velocity as a result of the opposite direction of magnetic moment of electrons with respect to external magnetic field.
