Energy Spectrum of Bloch Electrons Under Checkerboard Field Modulations
Ming Che Chang,Min-Fong Yang +1 more
TL;DR: In this paper, when static electric and magnetic modulations with a checkerboard pattern are superimposed on the uniform magnetic field, more structures and symmetries of the spectra are found, due to the additional adjustable parameters from the modulations.
Journal ArticleDOI
Optical spectra of quantum dots: A non-adiabatic approach
TL;DR: In this article, the optical spectra of small spherical GaAs/AlAs quantum dots are simulated using a non-adiabatic approach of the optical absorption, and the presence of accompanying resonances to the longitudinal optical phonon satellites is confirmed theoretically.
Journal ArticleDOI
Multiband energy spectra of spin-1/2 electrons with two-dimensional magnetic modulations
Ming Che Chang,Min Fong Yang +1 more
TL;DR: In this paper, the energy spectra of spin-1/2 electrons under two-dimensional magnetic field modulations are calculated beyond the one-band approximation, and it is shown that the zero-energy level seems to be unaffected by the modulation and is separated from higher energy levels with a nonzero energy gap.

Hysteresis effect in the v = 1 quantum Hall system under periodic electrostatic modulation
Ming Che Chang,Min-Fong Yang +1 more
TL;DR: In this article, the effect of a one-dimensional periodic electrostatic modulation on quantum Hall systems with filling factor {nu} = 1, is studied, and it is shown that when the amplitude of the modulation potential or the tilt angle of the magnetic field is varied, the system can undergo a first-order phase transition from a fully spinpolarized homogeneous state to a partially spin-polarised charge-density-wave state, and show hysteresis behavior of the spin polarization.
