Spin-Hall conductivity in a two-dimensional Rashba electron gas

Spin-Hall conductivity and Pauli susceptibility of 2D electron gas with Rashba spin-orbital interaction is studied theoretically in the semiclassical limit kFl 1. Static spin-Hall conductivity is shown to be zero for any nonvanishing disorder strength in the general case of the momentum-dependent Rashba velocity p and nonparabolic spectrum p . This result is derived both by an explicit diagramm...

Transport studies of reentrant integer quantum Hall states forming in the two-dimensional electron gas

Deng, Nianpei. Ph.D., Purdue University, December 2014. Transport Studies of Reentrant Integer Quantum Hall States Forming in The Two-dimensional Electron Gas. Major Professor: Gábor A. Csáthy. The two dimensional electron gas subjected to a magnetic field has been a model system in contemporary condensed matter physics which generated many beautiful experiments as well as novel fundamental con...

Robust electron pairing in the integer quantum hall effect regime.

Electron pairing is a rare phenomenon appearing only in a few unique physical systems; for example, superconductors and Kondo-correlated quantum dots. Here, we report on an unexpected electron pairing in the integer quantum Hall effect regime. The pairing takes place within an interfering edge channel in an electronic Fabry-Perot interferometer at a wide range of bulk filling factors, between 2...
