Nano Lett. 2014 Aug 13;14(8):4810-5. doi: 10.1021/nl502027r. Epub 2014 Jul 09.

We morph a silver nanodisk into a nanotriangle by producing a series of nanoparticles with electron beam lithography. Using electron energy loss spectroscopy (EELS), we map out the plasmonic eigenmodes and trace the evolution of edge and film modes...

High-finesse optical quantum gates for electron spins in artificial molecules.

Physical review letters

Troiani F, Molinari E, Hohenester U.
PMID: 12785913
Phys Rev Lett. 2003 May 23;90(20):206802. doi: 10.1103/PhysRevLett.90.206802. Epub 2003 May 20.

A doped semiconductor double-quantum-dot molecule is proposed as a qubit realization. The quantum information is encoded in the electron spin, thus benefiting from the long relevant decoherence times; the enhanced flexibility of the molecular structure allows one to map...

Phonon-assisted decoherence in the production of polarization-entangled photons in a single semiconductor quantum dot.

Physical review letters

Hohenester U, Pfanner G, Seliger M.
PMID: 17678402
Phys Rev Lett. 2007 Jul 27;99(4):047402. doi: 10.1103/PhysRevLett.99.047402. Epub 2007 Jul 24.

We theoretically investigate the production of polarization-entangled photons through the biexciton cascade decay in a single semiconductor quantum dot. In the intermediate state the entanglement is encoded in the polarizations of the first emitted photon and the exciton, where...

The recognition of pathogen surfaces by mannan-binding lectin activates MASP proteases, leading to complement activation. A crystal structure by Gingras et al. (2011) in this issue of Structure now shows how the collagen-like stems of mannan-binding lectin bind MASP-1...
