- 中文摘要: The Hamiltonian of an ellipsoidal-parabolic model electron moving in thepresence of electric and magnetic fields is in general very complicated. We findthat, by making use of three unitary operators, the Hamiltonian can be transformedinto a simple form, convenient for further discussions. To be specific, we haveclassified the problem into fourteen cases according to the geometrical arrangementof the electric and magnetic fields with respect to the Fermi ellipsoid for bothbulky and thin film samples. The solvable condition in each case has also beenclearly studied.
