Revisiting Molecular Dissociation in Density Functional Theory: A Simple Model
David G. Tempel, Todd J. Martinez, Neepa T. Maitra
A two-electron one-dimensional model of a heteroatomic molecule composed of two open-shell atoms is considered. Including only two electrons isolates and examines the effect that t…
Enhanced current quantization in high frequency electron pumps in a perpendicular magnetic field
S. J. Wright, M. D. Blumenthal, Godfrey Gumbs +8
We present experimental results of high frequency quantized charge pumping through a quantum dot formed by the electric field arising from applied voltages in a GaAs/AlGaAs system…
Optimum unambiguous identification of d unknown pure qudit states
Ulrike Herzog, Janos A. Bergou
We address the problem of unambiguously identifying the state of a probe qudit with the state of one of d reference qudits. The reference states are assumed pure and linearly indep…
Magnetoplasmons in layered graphene structures
Oleg L. Berman, Godfrey Gumbs, Yurii E. Lozovik
We calculate the dispersion equations for magnetoplasmons in a single layer, a pair of parallel layers, a graphite bilayer and a superlattice of graphene layers in a perpendicular…
Creation of high-quality long-distance entanglement with flexible resources
Bing He, Yu-Hang Ren, Janos A. Bergou
We present a quantum repeater protocol that generates the elementary segments of entangled photons through the communication of qubus in coherent states. The input photons at the r…
Universal entangler with photon pairs in arbitrary states
Bing He, Yuhang Ren, Janos A. Bergou
We propose a setup that transforms a photon pair in arbitrary rank-four mixed state, which could also be unknown, to a Bell state. The setup involves two linear optical circuits pr…
