Hilbert-space fragmentation, multifractality, and many-body localization
(2021)Investigating many-body localization (MBL) using exact numerical methods is limited by the exponential growth of the Hilbert space. However, localized eigenstates display multifractality and only extend over a vanishing ... -
History of Magnetism and Basic Concepts
(Springer, Cham, 2021)Magnetism is a microcosm of the history of science over more than two millennia. The magnet allows us to manipulate a force field which has catalyzed an understanding of the natural world that launched three revolutions. ... -
Hole blocking in carbon nanotube-polymer composite organic light-emitting diodes based on poly (m-phenylene vinylene-co-2, 5-dioctoxy-p-phenylene vinylene)
(2000)In order to investigate the role of carbon nanotubes in a polymer matrix, organic light-emitting diodes were fabricated from a polymer composite composed of poly ~ m -phenylene vinylene-co-2,5-dioctoxy- p -phenyle ... -
Homologous size-extension of hybrid vanadate capsules - Solid state structures, solution stability and surface deposition
(2014)The dimensions and cavity sizes of the molecular capsules with the general formula [V10O18L4]10- can be controlled modularly through the nature of the bifunctional, rigid organophosphonate ligands L1 and L2 (L1 = ... -
The hot Jupiter and magnetic activity of V830 Tau
(2017)We report results of an extended spectropolarimetric and ph otometric monitoring of the weak- line T Tauri star V830 Tau and its recently-detected newborn close-in giant planet. Our obser- vations, carried out within ... -
Hot-Volumes as Uniform and Reproducible SERS-Detection Enhancers in Weakly-Coupled Metallic Nanohelices
(2017)Reproducible and enhanced optical detection of molecules in low concentrations demands simultaneously intense and homogeneous electric fields acting as robust signal amplifiers. To generate such sophisticated optical ... -
How can Sodium MRI techniques help us understand acute stroke?
(2012)This article addresses the potential usefulness of sodium MRI in the acute phase of stroke, asking whether the additional time required to acquire high quality sodium images is justified in the time-critical minutes following ... -
How do phonons relax molecular spins?
(American Association for the Advancement of Science (AAAS), 2019)The coupling between electronic spins and lattice vibrations is fundamental for driving relaxation in magnetic materials. The debate over the nature of spin-phonon coupling dates back to the 1940s, but the role of spin-spin, ... -
The HST absorption line key project. IX. Emission line studies of PG 2251+113
(American Astronomical Society, 1994)We present Hubble Space Telescope (HST) and quasi-simultaneous ground-based observations of the z = 0.3252 QSO PG 2251113. We find a correlation between line widths and the critical density for de-excitation of the forbidden ... -
The HST quasar absorption line key project. 4: HST faint-object spectrograph and ground-based observations of the unusual low-redshift broad absorption-line quasi-stellar object PG 0043+039
(American Astronomical Society, 1994)Hubble Space Telescope Faint Object Spectrograph (HST FOS) observations have shown that the spectrum of the low-redshift (zem approximately equal to 0.384) QSO PG 0043+039 exhibits weak broad absorption lines (BALs). The ... -
The Hubble deep field south: formulation of the observing campaign
(University of Chicago Press, 2000)Deep, multiband observations of high Galactic latitude fields are an essential tool for studying topics ranging from Galactic structure to extragalactic background radiation. The Hubble Deep Field (HDF-N) observations ... -
The Hubble Deep Field South: STIS imaging
(American Astronomical Society, 2000)We present the imaging observations made with the Space Telescope Imaging Spectrograph (STIS) of the Hubble Deep Field South. The field was imaged in four bandpasses: a clear CCD bandpass for 156 ks, a long-pass filter for ... -
A Hubble space telescope faint object spectrograph survey for broad absorption lines in a sample of low-redshift weak [O iii] quasi-stellar objects
(1997)The study by Boroson & Meyers led to the suggestion that radio-quiet QSOs with weak [O III] and strong Fe II emission spectra form a class of QSOs that has a high probability of exhibiting broad absorption lines (BALs) in ... -
Hubble space telescope observations of the gravitationally lensed cloverleaf broad absorption line QSO H1413+1143: imaging
(American Astronomical Society, 1996)An analysis of Hubble Space Telescope (HST) Wide Field Planetary Camera (WFPC) and Wide Field Planetary Camera 2 (WFPC2) images of the gravitationally lensed Cloverleaf broad absorption line quasi-stellar object (QSO) ... -
Hybrid density functional theory applied to magnetite: Crystal structure, charge order, and phonons
(2009)The electronic structure and equilibrium structure of magnetite (Fe3O4) in the high temperature cubic Fd3¯m and low temperature monoclinic P2/c unit cells have been computed using the Perdew-Wang generalized gradient ... -
Hybrid DFT calculation of 57Fe NMR resonances and orbital order in magnetite
(2014)The crystal structure and charge and orbital order of magnetite below the Verwey temperature are calculated using a first-principles hybrid density functional theory (DFT) method. The initial atomic positions in ... -
Hybrid metal nanostructure arrays for colour printing
(2016)Nanoscale metasurfaces have become an area of growing interest in recent years with the promise of new functionalities. One area that has received a lot of attention is sub-diffraction limit printing. We demonstrate the ... -
Hybrid organic-inorganic spin-on-glass CuCl films for optoelectronic applications
(2009)Cuprous halides are among the most studied inorganic materials for excitonic related linear/non-linear optical processes due to their large excitonic binding energies (~190 and 108 meV for CuCl and CuBr, respectively). In ... -
