HEAT CAPACITY AND MAGNETIZATION OF QUANTUM DOTS IN HIGH MAGNETIC FIELDS(Session I : Cross-Disciplinary Physics, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations)

Abstract

We investigate the electronic structure of quantum dots with two electrons in high magnetic fields and find that the combined effect of electron-electron interactions and hybrid-magnetoelectric quantization governs the whole energy spectrum. The spin transitions in the ground state are found to strongly depend on the shape of the quantum dot and clearly appear in heat capacity and magnetization at sufficiently low temperature.
