    Abstract

    We show that a quantum dot in the fractional Hall regime exhibits mesoscopic oscillations in its thermodynamic properties with a period which is a multiple of the period for free electrons. Our calculations are performed for parabolic quantum dots with hard-core electron-electron interactions and are exact in the strong field limit for k(B)T smaller than the fractional Hall gap. Explicit expressions are given for the temperature dependence of the amplitude of the oscillations.
