Polarized substructural session types
Concurrent processes can be extremely difficult to reason about, both for programmers and formally. One approach to coping with this difficulty is to study new programming languages and type features such as Session Types. Session types take as their conceptual notion of concurrency as a collection …

Inclusive scattering of polarized electrons from polarized protons in the Delta-excitation region with BLAST
<p>Inclusive scattering of polarized electrons from polarized protons has been studied using the BLAST detector at MIT-Bates Linear Accelerator Center. The Bates Large Acceptance Spectrometer Toroid (BLAST) is a detector designed to study in a comprehensive and precise way the spin-dependent …

Spin Polarized Transport in Nanoscale Devices
… (or half-metallic) material which injects spin polarized electrons in the channel. During transit, the spin polarizations of the electrons are controllably rotated by a gate electric field mediated spin-orbit coupling effect. The drain contact is ferromagnetic (or half-metallic) as well and the …

Coherent control of polarized neutron interferometry
… to magnetic materials characterization using polarized neutron interferometry (NI). We describe a split path spin-based interferometer geometry that uses the Bragg interferometer to separate two paths where spin states are independently manipulated. The final measurement is made on the spin …

Fabrication Methods for Polarized Light Collages
… we discuss the best methods of fabricating polarized art collages, inspired by the artwork of Austine Wood-Comarow that creates brightly colored images from cellophane, a colorless birefringent material, placed in between two polarizers. Her artwork appears alive as the colors morph between …

Analysis of scattered protons in deuteron electrodisintegration with a polarized electron beam and an internal polarized target
… momentum transfer. BLAST combines a high-duty polarized electron beam, an Atomic Beam Source (ABS) target of highly-polarized deuterium atoms, and a large-acceptance spectrometer detector. This work reports on measurements of A.4 and Aid for Q2 ranges between 0.1 and 0.5 (GeV/c)2. Comparisons …

Quantitative anisotropy imaging with polarized interference microscopy
Optical anisotropy measurement is essential for material characterization and biological imaging. Many optical anisotropy imaging techniques have been developed, such as fluorescence polarization microscopy(FPM), liquid crystal based polarization microscopy (LC Polscope), polarization state optical …

Proton Compton scattering with polarized γ rays
… degree center of mass scattering angle with the polarized photon beam at LEGS. Compton scattering is an important probe of the nucleon structure and its excited states. Polarization degrees of freedom reveal more information than unpolarized observables. This experiment measured, for the first …

Surface studies using spin-polarized ion neutralization spectroscopy
Spin-polarized ion neutralization spectroscopy (SPINS), in which a beam of electron-spin-polarized He+ ions is directed onto a surface and analysis is done of the electrons ejected from the surface as a result of ion neutralization, is a unique tool for surface studies that has unparalleled surface …

A polarized ≥He ion source: Measuring the polarization
… uses the principle of optical pumping to produce polarized He ions for extraction and acceleration. The design of an experiment to measure the degree of polarization of the ions is described. 3He+ ions are accelerated to an energy of approximately 300 keV and produce protons through the 2H(3 He,p) …

Ferromagnetic manganites: spin-polarized conduction and competing interactions
Electronic properties of solids are vitally important for modern technology, one may think of microelectronics, magnetic data storage, communication technologies and others. Sometimes, it seems possible to postpone the step of fundamental understanding when starting the application of a new …
