Effects of Zeeman spin splitting on the modular symmetry in the quantum Hall effect
D. R. Hang, R. B. Dunford, Gil-Ho Kim +7
Magnetic-field-induced phase transitions in the integer quantum Hall effect are studied under the formation of paired Landau bands arising from Zeeman spin splitting. By investigat…
Generalized master equation with nonhermitian operators
C. F. Huang, K. -N. Huang
By extending the mean-field Hamiltonian to include nonhermitian operators, the master equations for fermions and bosons can be derived. The derived equations reduce to the Markoff…
Studies of the Temperature-Driven Flow Lines and Phase Transitions in a Two-Dimensional Si/SiGe Hole System
C. T. Liang, C. F. Huang, Yu-Ming Cheng +3
We have performed low-temperature transport experiments on a Si/SiGe hole system. The measured transverse and longitudinal condductivities and allow us to study t…
From quantum master equation to random walk
C. F. Huang
It is shown in this paper that the quantum master equation can be mapped to a modified continuous time random walk (CTRW) if the relaxation term is composed of transitions over a s…
