Abstract

We investigate the thermal properties of circular semiconductor quantum dots in high magnetic fields using finite-temperature Hartree-Fock techniques. We demonstrate that for a given magnetic field strength quantum dots undergo various shape phase transitions as a function of temperature, and we outline possible observable consequences.
