Anamolous conductance plateau in an asymmetrically biased InAs/InAlAs quantum point contact
P. P. Das, K. B. Chetry, N. Bhandari +4
The appearance and evolution of an anomalous conductance plateau at 0.4 (in units of 2e2/h) in an In0.52Al0.48As/InAs quantum point contact (QPC), in the presence of lateral spin-o…
Influence of Impurity Scattering on the Conductance Anomalies of Quantum Point Contacts with Lateral Spin-Orbit Coupling
J. Wan, M. Cahay, P. P. Das +1
We have recently shown that asymmetric lateral spin orbit coupling (LSOC) resulting from the lateral in-plane electric field of the confining potential of a side-gated quantum poin…
Spin Texture in Quantum Point Contacts in the Presence of Lateral Spin Orbit Coupling
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green's function formalism is used to study in detail the ballistic conductance of asymmetrically biased side-gated quantum point contacts (QPCs) in the presence…
Selective dilution and magnetic properties of La_{0.7}Sr_{0.3}Mn_{1-x}M'_xO_3 (M' = Al, Ti)
D. N. H. Nam, L. V. Bau, N. V. Khiem +5
The magnetic lattice of mixed-valence Mn ions in LaSrMnO is selectively diluted by partial substitution of Mn by Al or Ti. The ferromagnetic transition temperat…
Dynamic Scaling and Two-Dimensional High-Tc Superconductors
D. R. Strachan, C. J. Lobb, R. S. Newrock
There has been ongoing debate over the critical behavior of two-dimensional superconductors; in particular for high Tc superconductors. The conventional view is that a Kosterlitz-T…
