Hysteresis in the Conductance of Asymmetrically Biased GaAs Quantum Point Contacts with in-plane Side Gates
N. Bhandari, M. Dutta, J. Charles +2
We have observed hysteresis between the forward and reverse sweeps of a common mode bias applied to the two in-plane side gates of an asymmetrically biased GaAs quantum point conta…
Possible origin of the 0.5 plateau in the ballistic conductance of quantum point contacts
J. Wan, M. Cahay, P. Debray +1
A non-equilibrium Green function formalism (NEGF) is used to study the conductance of a side-gated quantum point contact (QPC) in the presence of lateral spin-orbit coupling (LSOC)…
Finite-Size Effects and Dynamical Scaling in Two-Dimensional Josephson Junction Arrays
J. Holzer, R. S. Newrock, C. J. Lobb +2
In recent years many groups have used Fisher, Fisher, and Huse (FFH) dynamical scaling to investigate and demonstrate details of the superconducting phase transition. Some attentio…
Paramagnetic Meissner Effect in Multiply-Connected Superconductors
A. P. Nielsen, A. B. Cawthorne, P. Barbara +4
We have measured a paramagnetic Meissner effect in Nb-Al2O3-Nb Josephson junction arrays using a scanning SQUID microscope. The arrays exhibit diamagnetism for some cooling fields…
