Thermodynamic and magnetic properties of the confined neutral Fermi systems

Abstract

The heat capacity and magnetic susceptibility of free Fermi systems confined to spherical pores and to 2D circles are studied theoretically. It is shown that taking into account the existence of a pore size distribution leads to the smoothing of magnetic susceptibility oscillations. The areal density dependencies of the heat capacity and magnetic susceptibility of the free 2D Fermi gas are obtained. © 2002 Elsevier Science B.V. All rights reserved.
