Spin Current Generation and Detection in the Presence of AC Gate
A. G. Mal'shukov, C. S. Tang, C. S. Chu +1
We predict that in a narrow gap III-V semiconductor quantum well or a wire an observable spin current can be generated with a time dependent gate to modify the Rashba spin-orbit co…
High Energy Astrophysical Tau Neutrinos: The Expectations
H. Athar
Aspects related to production, propagation and prospects for observationsof high energy astrophysical tau neutrinos originating from some representativeextra terrestrial sources su…
Theory for Slightly Doped Antiferromagnetic Mott Insulators
T. K. Lee, Chang-Ming Ho, Naoto Nagaosa +1
Trial wavefunctions, constructed explicitly from the unique 2-dimensional Mott insulating state with antiferromagnetic order, are proposed to describe the low-energy states of a Mo…
Transport spectroscopy in a time-modulated open quantum dot
C. S. Tang, Y. H. Tan, C. S. Chu
We have investigated the time-modulated coherent quantum transport phenomena in a ballistic open quantum dot. The conductance and the electron dwell time in the dots are calcul…
SO(5) as a Critical Dynamical Symmetry in the SU(4) Model of High-Temperature Superconductivity
Lian-Ao Wu, Mike Guidry, Yang Sun +1
An SU(4) model of high-temperature superconductivity and antiferromagnetism has recently been proposed. The SO(5) group employed by Zhang is embedded in this SU(4) as a subgroup, s…
Epidemic thresholds on scale-free graphs: the interplay between exponent and preferential choice
Ph. Blanchard, Ch. -H. Chang, T. Krueger
We show for a model of scale-free graphs with biased partner choice that knowing the exponent for the degree distribution is in general not sufficient to decide epidemic threshold…
