Ultimate crack and lack of any security in the statistical key exchange protocol with random signals and feedback
Ultimate crack Quantum Physics
2010/11/8
We deterministically crack the secure, statistical key exchange protocol based on feedback proposed by Pao-Lo Liu [ J. Lightwave Techology 27 (2009) pp. 5230-34]. The crack is ultimate and absolute be...
Constraints on anomalous spin-spin interactions from spin-exchange collisions
Constraints anomalous spin-spin interactions spin-exchange collisions
2010/11/11
Measured and calculated cross sections for spin-exchange between alkali atoms and noble gases (specifically sodium and helium) are used to constrain anomalous spin-dependent forces between nuclei at t...
In this work, the exchange energy J for a system of two laterally-coupled quantum dots, each one with an electron, is calculated analytically and in a detailed form, considering them as hydrogen-like ...

Exchange-Correlation Effects in the Impurity-Limited Mobility of GaAs Quantum Wires
Exchange-Correlation Effects GaAs Quantum Wires Impurity-Limited Mobility
2010/4/16
We study the many-body effects described by the local-field corrections on the mobility of quasi-one dimensional electron systems. The low temperature mobility due to remote-impurity doping and interf...
