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 ...
Efficient conducting channels formed by the ð-ð stacking in single [2,2]paracyclophane molecules
(2012)
The electronic transportproperties of single [2,2]paracyclophane molecules directly connected to gold and platinumelectrodes have been investigated both theoretically and experimentally by using first-principles quantum ...
Magnetoresistance in nanostructured Co-Ag prepared by mechanical alloying
(IEEE, 1993)
Fine cobalt and silver powders have been ball-milled to yield a granular solid of composition Co30Ag70 in the form of coarse powder. The material is an intimate mixture of grains of fcc Co in a silver matrix. The cobalt ...
Influence of ferromagnetic substrate on the magnetoresistance of Cr film across a nonmagnetic insulating layer
(2003)
(5 nm) Cr/(x?nm) MgO/Mn0.52Zn0.48Fe2O4 (MnZn spinel) substrate (1<x<7?nm), as well as (5 nm) Cr/(7 nm) MgO/glass substrate structures have been grown using molecular beam epitaxy. The influence of the MnZn spinel on the ...
A further look at waveguide lasers
(IEEE, 1998)
A new approach to the dynamical evolution of a waveguide laser is presented which goes beyond the usual Maxwell-Bloch (MB) equations in that it takes fully into account the phase of the matter quantum field that describes ...
Outbursts of classical symbiotics: Multi-wavelength observations of the 2000-2001 outburst of Z Andromedae
(Astronomical Society of the Pacific, 2002)
We describe the first results from a program of multi-wavelength monitoring of symbiotic binary stars in outburst. The prototypical symbiotic star Z Andromedae was observed extensively at radio, optical, far-UV, and X-ray ...
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. ...
Surface phonons of the Si(111):In-(4 x 1) and (8 x 2) phases
(2007)
The reversible phase transition of the Si(111):In-(4?1) surface has been studied using Raman spectroscopy and the symmetry, frequencies, and linewidths of the surface phonon modes have been determined. Dramatically different ...
Finite-momentum condensation in a pumped microcavity
(2010)
We calculate the absorption spectra of a semiconductor microcavity into which a nonequilibrium exciton population has been pumped. We predict strong peaks in the spectrum corresponding to collective modes analogous to the ...
