Conductance through a helical state in an InSb nanowire
Jakob Kammhuber, Maja C Cassidy, Fei Pei +7
The motion of an electron and its spin are generally not coupled. However in a one dimensional material with strong spin-orbit interaction (SOI) a helical state may emerge at finit…
Conductance Quantization at zero magnetic field in InSb nanowires
Jakob Kammhuber, Maja C. Cassidy, Hao Zhang +10
Ballistic electron transport is a key requirement for existence of a topological phase transition in proximitized InSb nanowires. However, measurements of quantized conductance as…
Large spin-orbit coupling in carbon nanotubes
G. A. Steele, F. Pei, E. A. Laird +3
It has recently been recognized that the strong spin-orbit interaction present in solids can lead to new phenomena, such as materials with non-trivial topological order. Although t…
A valley-spin qubit in a carbon nanotube
Edward A. Laird, Fei Pei, Leo. P. Kouwenhoven
Although electron spins in III-V semiconductor quantum dots have shown great promise as qubits, a major challenge is the unavoidable hyperfine decoherence in these materials. In gr…
Valley-spin blockade and spin resonance in carbon nanotubes
Fei Pei, Edward A. Laird, Gary A. Steele +1
Manipulation and readout of spin qubits in quantum dots made in III-V materials successfully rely on Pauli blockade that forbids transitions between spin-triplet and spin-singlet s…
Ab initio study on the electronic and magnetic properties of CaFe2As2 within a GGA + negative U approach
S. Wu, G. Wang, F. Pei +4
This paper has been withdrawn by the author due to the error in figure 2, we did not optimized c-value of the supercell, so the results can not give the true physics of this materi…
