Multifractal Specific Heat of Disordered Mesoscopic Systems

It is shown that multifractal data on critical behavior of wavefunctions at the Anderson metal–insulator transition obtained in numerical simulations are in good agreement with constant specific-heat multifractal approximation for three and two dimensional cases (in the last case in high magnetic field). A relation of this approximation to the parabolic multifractal approximation is also briefly discussed.
