Phase diagram of the fully frustrated transverse-field Ising model on the honeycomb lattice

Frédéric Mila, Jean-David Picon, Tommaso Coletta

Motivated by the current interest in the quantum dimer model on the triangular lattice, we investigate the phase diagram of the closely related fully frustrated transverse-field Ising model on the honeycomb lattice using classical and semiclassical approxi ...

Exciton-polariton spin switches

Romuald Houdré, Timothy Chi Hin Liew

Integrated switching devices comprise the building blocks of ultrafast optical signal processing(1,2). As the next stage following intensity switching(1,3,4), circular polarization switches(5-9) are attracting considerable interest because of their applica ...

Broken symmetries in macromolecular crystallography: phasing from unmerged data

The space-group symmetry of a crystal structure imposes a point-group symmetry on its diffraction pattern, giving rise to so-called symmetry-equivalent reflections. Instances in macromolecular crystallography are discussed in which the symmetry in reciproc ...

Topological stability of the half-vortices in spinor exciton-polariton condensates

Hugo Pierre Alexandre Flayac

Half-vortices have been recently shown to be the elementary topological defects supported by a spinor cavity exciton-polariton condensates with spin-anisotropic interactions [Y. G. Rubo, Phys. Rev. Lett. 99, 106401 (2007)]. A half-vortex is composed by an ...

Polarization Properties of Columnar Quantum Dots: Effects of Aspect Ratio and Compositional Contrast

Philipp Ridha

We report a systematic theoretical and experimental investigation of the polarization properties of columnar quantum dots (CQDs) with extremely large aspect ratio and high compositional contrast. A strong variation of the polarization of the dominant inter ...

Instrument-independent specification of the diffraction geometry and polarization state of the incident X-ray beam

This work augments the proposal of Schwarzenbach & Flack [J. Appl. Cryst. (1989), 22, 601-605], who have advocated the use of a diffractometer-independent definition of the azimuthal angle

\psi

to specify the diffractiongeometry of a Bragg reflection. It ...

Polarization sensitive diffuser

Hans Peter Herzig, Toralf Scharf

With help of liquid crystal polymers (LCP) a polarization sensitive diffuser has been realized. By using convex microstructures made of LCP and an index matching layer, two distinct functions depending on the orientation of the device and the polarization ...

A novel formalism for the study of the electronic and optical properties of high symmetry heterostructures

Sascha Dalessi

The theories used up to now to model theoretically and numerically nanostructures, and more specifically semiconductor heterostructures, do not allow to include efficiently at the envelope function level, in a k · p approach, the effects imposed by a possi ...

Excited excitonic states observed in semiconductor quantum dots using polarization resolved optical spectroscopy

Elyahou Kapon, Alok Rudra, Daniel Oberli, Valentina Troncale

We present results on the polarization-resolved photoluminescence emitted from InGaAs/AlGaAs single quantum dots (QDs) grown in inverted tetrahedral pyramids. The emitted light was detected for two mutually perpendicular linear polarization directions in t ...

Design and performance of a DNP prepolarizer coupled to a rodent MRI scanner

Rolf Gruetter, Arnaud Comment, Sami Jannin, Jacques Van Der Klink, Fiodar Kurdzesau

For most of the last forty years, the techniques of Dynamic Nuclear Polarization (DNP) have been confined to particle-physics laboratories building polarized targets, but recently it has been shown that samples similar to a solid target can be transformed ...
