Abstract
The heat capacity of two interacting electrons confined in a quantum dot presented in a magnetic field has been calculated by solving the Hamiltonian using the exact diagonalization method. The statistical average energies for confined and interacting electrons have been computed for various values of magnetic fields, confining frequency and temperature. We had investigated the dependence of the heat capacity on quantum dot Hamiltonian’s parameters and temperature. The singlettriplet transitions in the ground state of the quantum dot spectra and the corresponding jumps in the heat capacity curves had been shown. The comparisons show that our results are in very good agreement with theoretical reported works.
