Abelian and non-abelian anyons in integer quantum anomalous Hall effect and topological phase transitions via superconducting proximity effect
Abelian non-abelian anyons integer quantum anomalous Hall effect effect
2010/12/27
We study the quantum anomalous Hall effect described by a class of two-component Haldane models on square lattices. We show that the latter can be transformed into a pseudospin triplet p+ip-wave paire...

Thermal Expansion the Temperature Dependence Excitonic Transitions GaAs and AlGaAs
2010/10/21
Photoluminescence and photoreflectance measurements have been used to determine excitonic transitions in the ternary AlxGa1−xAs alloy in the temperature range from 2 to 300 K. The effect of the ...
E2/M1 Multipole Mixing Ratios of Transitions in Erbium Isotopes
IBA-2 Deformation parameter Quadrupol moment Mixing ratios
2010/4/12
Erbium isotopes (Z = 64) lie in the transitional region that occurs at the middle of the range of deformed nuclei. g -ray E2/M1 mixing ratios for selected transitions in 166-168Er are calculated in th...
