ElectronsWave functionsQuantum mechanicsIt is shown for electrons in a periodic potential and a uniform magnetic field that there exists a Hermitian 'mixed-band' effective Hamiltonian of the form W sub alpha, gamma (p-eA/c), where p is the momentum and A is the vector potential. The off-...

Quantum states and Hall conductances of electrons in n-type heterojunctions and holes in p-type heterojunctions in a field of a lateral superlattice and a perpendicular magnetic field were studied. It is shown that Quantum states and Hall conductances of electrons in n-type heterojunctions and ...
We find a quantum group structure in two-dimensional motion of the nonrelativistic electron in a uniform magnetic field. A recombination of the W_∞ algebra enables us to define the quantum algebra of which deformation parameter is given by some physical quantities. The obtained quantum algebra com...

Bloch theorem is a fundamental theorem in condensate matter physics and describes how the wave function of electrons behaviors in the periodic potential. In optics or electromagnetism, electromagnetic waves propagate in a similar fashion in periodic structures, as such the Bloch theorem can be used to...
It is shown that an extended q-deformed su(2) algebra with an extra ("Schwinger") term can describe Bloch electrons in a uniform magnetic field with an additional periodic potential. This is a generalization of the analysis of Bloch electrons by Wiegmann and Zabrodin. By using a ...
physicsatomic physicsThe free energy and zero field magnetic susceptibility for electrons in a potential, periodic along the uniform magnetic field, are obtained exactly. The de Haas-van Alphen effect is discussed for a simple band structure and is shown to be consistent with the semiclassical ...
