Finite-temperature transitions in bilayer quantum Hall systems
Min-Fong Yang,Ming Che Chang +1 more
TL;DR: In this paper, the influence of an in-plane magnetic field B-parallel on the finite-temperature phase transitions in bilayer quantum Hall systems was examined and it was found that there can exist two types of finite-time phase transitions: the first is the Kosterlitz-Thouless (KT) transitions, which have an unusual non-monotonic dependence on B_\parallel; the second type originates from the crossing of energy levels and always increases with B_parallel.
Journal ArticleDOI
Persistent currents in a graphene ring with armchair edges
TL;DR: In this paper, by folding a graphene ribbon to a ring and threading it by a magnetic flux, the authors study the persistent charge and spin currents in the tight-binding limit.
Journal ArticleDOI
Persistent spin current in mesoscopic ferrimagnetic spin ring
TL;DR: In this article, the persistent magnetization current of a mesoscopic ferrimagnetic ring in a non-uniform magnetic field was studied using a semiclassical approach, and it was shown that at low temperature, the current shows activation behavior because of the field-induced gap.
Se p 20 05 Středa-like formula in spin Hall effect
Min Fong Yang,Ming Che Chang +1 more
TL;DR: In this paper , a generalized Středa formula for spin transport in spin-orbit coupled systems is derived, where the spin is not conserved in general, and the quantization is not exact.
Journal ArticleDOI
Carrier self-energy and photoluminescence spectrum in quantum Hall system
Ming Che Chang,H. H. Cheng +1 more
TL;DR: In this paper, the authors studied the effect of the width of the quantum well and the strength of disorder on the electron self-energy in a quantum Hall system. And they found that a wider quantum well has a smaller self energy correction, and a stronger disorder yields a smaller energy oscillation with respect to the magnetic field.
