How Gabriel Harvey read tragedy
Tania Demetriou
Oct 18, 2021
Abstract: In 1579, Gabriel Harvey bound together in a composite collection a surprising group of texts: an Italian grammar, an Italian translation of Terence’s comedies, Lodovico Dolce’s Italian rifacimenti of Euripides’ Medea...

Ballistic Hall Photovoltammetry of Magnetic Resonance in Individual Nanomagnets
We report on ballistic Hall photo-voltammetry as a contactless probe of localized spin excitations. Spins resonating in the near-field of a two-dimensional electron system are shown to induce a long range electromotive force...

Single-Photon Superradiance from a Quantum Dot.
Petru Tighineanu, Raphaël S Daveau, Tau B Lehmann, Harvey E Beere, David A Ritchie, Peter Lodahl, Søren Stobbe
Nov 21, 2018
We report on the observation of single-photon superradiance from an exciton in a semiconductor quantum dot. The confinement by the quantum dot is strong enough for it to mimic a two-level atom, yet sufficiently weak to ensure...
Vietnamese Americans' Experiences With Hurricane Harvey
Immigrant populations in the United States continue to receive inadequate attention in disaster preparedness, response, and recovery despite the increasing frequency and intensity of disasters and catastrophic events. This...

An in-plane photoelectric effect in two-dimensional electron systems for terahertz detection.
Wladislaw Michailow, Peter Spencer, Nikita W Almond, Stephen J Kindness, Robert Wallis, Thomas A Mitchell, Riccardo Degl'Innocenti, Sergey A Mikhailov, Harvey E Beere, David A Ritchie
May 17, 2022
Many mid- and far-infrared semiconductor photodetectors rely on a photonic response, when the photon energy is large enough to excite and extract electrons due to optical transitions. Toward the terahertz range with photon...
Continuous-wave highly-efficient low-divergence terahertz wire lasers.
Simone Biasco, Katia Garrasi, Fabrizio Castellano, Lianhe Li, Harvey E Beere, David A Ritchie, Edmund H Linfield, A Giles Davies, Miriam S Vitiello
Sep 20, 2018
Terahertz (THz) quantum cascade lasers (QCLs) have undergone rapid development since their demonstration, showing high power, broad-tunability, quantum-limited linewidth, and ultra-broadband gain. Typically, to address...
Crossover between magnetic and electric edges in quantum Hall systems
We report on the transition from magnetic edge to electric edge transport in a split magnetic gate device which applies a notch magnetic field to a two-dimensional electron gas. The gate bias allows tuning the overlap of...

Photovoltage detection of Damon-Eshbach and dipolar edge spin waves of nanomagnets with two-dimensional electron gas system
Najla Almulhem, Maksym Stebliy, Alain Nogaret, Jean-Claude Portal, Harvey Beere, D A Ritchie
Sep 01, 2018
We report on a photovoltage technique that we use to probe spin excitations on submicron scales where surface effects play a dominant role. Localized spin wave modes were detected through the photovoltage induced in a...

Extracting and re-using research data from chemistry e-theses
Peter Morgan, Jim Downing, Peter Murray-Rust, Diana Stewart, Alan Tonge, Joseph A Townsend, Matt Harvey, Henry S Rzepa
Feb 14, 2011
Scientific e-theses are data-rich resources, but much of the information they contain is not readily accessible. For chemistry, the SPECTRa-T project has addressed this problem by developing data-mining techniques to extract...
Photovoltage spectroscopy of dipolar spin waves in Dy micromagnets
