A discretevelocity, stationary Wigner equation
(AIP Publishing, 200011)This paper is concerned with the onedimensional stationary linear Wigner equation, a kinetic formulation of quantum mechanics. Specifically, we analyze the wellposedness of the boundary value problem on a slab of the ... 
A lowfrequency radio array for space
(EDP SCIENCES, 198804)At the lowest radio frequencies (<30 MHz), the Earth's ionosphere transmits poorly or not at all. This relatively unexplored region of the electromagnetic spectrum is thus an area where high resolution, high sensitivity ... 
A new method of surface resistance measurement with a niobium triaxial cavity working at 2 K
(AIP Publishing, 199307)A 1.5GHz superconducting niobium triaxial cavity has been fabricated to study residual surface resistance of superconducting materials at 2 K. Unlike many other structures where the entire test samples have to be placed ... 
A New Population of Highz, Dusty Lyα Emitters and Blobs Discovered by WISE: Feedback Caught in the Act?
(IOP PUBLISHING LTD, 201306)By combining data from the NASA Widefield Infrared Survey Explorer (WISE) mission with optical spectroscopy from the W. M. Keck telescope, we discover a midIR color criterion that yields a 78% success rate in identifying ... 
A note on the iteration of the Chandrasekhar nonlinear Hequation
(AIP Publishing, 197904)An iteration scheme to solve the Chandrasekhar H equation in the form H (_) ={1___F_ 1 0[_ (s) H (s)]/(s +_) d s}_1 is shown to converge monotonically and uniformly. 
A Population of z > 2 FarInfrared HerschelSpireSelected Starbursts
(IOP Publishing Ltd., 201212)We present spectroscopic observations for a sample of 36 HerschelSpire 250500 mu m selected galaxies (HSGs) at 2 < z < 5 from the Herschel Multitiered Extragalactic Survey. Redshifts are confirmed as part of a large ... 
A precision test for an extra spatial dimension using blackholepulsar binaries
(IOP Publishing Ltd., 201108)We discuss the observable effects of enhanced black hole mass loss in a black holeneutron star (BHNS) binary, due to the presence of a warped extra spatial dimension of curvature radius L in the braneworld scenario. For ... 
A redshift survey of Herschel farinfrared selected starbursts and implications for obscured star formation
(IOP Publishing Ltd., 201212)We present Keck spectroscopic observations and redshifts for a sample of 767 HerschelSPIRE selected galaxies (HSGs) at 250, 350, and 500 mu m, taken with the Keck I Low Resolution Imaging Spectrometer and the Keck II DEep ... 
A Water Maser Flare in W49N: Amplification by a Rotating Foreground Cloud
(IOP PUBLISHING LTD, 199812)We monitored the 22 GHz H2O maser emission toward W49N from December 1989 through May 1990. During this period we observed an outburst in a component at 66.25 km s(1). The flux density of the flaring component increased ... 
ACD estimation of the Sparameter revisited
(Elsevier Science Bv, 19970529) 
An adaptive variational algorithm for exact molecular simulations on a quantum computer
(Springer Nature, 20190708)Quantum simulation of chemical systems is one of the most promising nearterm applications of quantum computers. The variational quantum eigensolver, a leading algorithm for molecular simulations on quantum hardware, has ... 
Aging in coarsening diluted ferromagnets
(American Physical Society, 201010)We comprehensively study nonequilibrium relaxation and aging processes in the twodimensional randomsite Ising model through numerical simulations. We discuss the dynamical correlation length as well as scaling functions ... 
Aging phenomena in the twodimensional complex GinzburgLandau equation
The complex GinzburgLandau equation with additive noise is a stochastic partial differential equation that describes a remarkably wide range of physical systems which include coupled nonlinear oscillators subject to ... 
Aging processes in systems with anomalous slow dynamics
(American Physical Society, 20130114)Recently, different numerical studies of coarsening in disordered systems have shown the existence of a crossover from an initial, transient, powerlaw domain growth to a slower, presumably logarithmic, growth. However, ... 
Algebroids, heterotic moduli spaces and the Strominger system
(Springer, 20140708)In this paper we study compactifications of heterotic string theory on manifolds satisfying the partial derivative(partial derivative) over bar lemma. We consider the Strominger system description of the low energy ... 
The ALPS project release 2.0: open source software for strongly correlated systems
(Iop Publishing Ltd, 20110501)We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries and application programs for the simulation of strongly correlated quantum ... 
Aluminum plasmonic nanostructures for improved absorption in organic photovoltaic devices
(AIP Publishing, 201103)We model the absorption enhancement in organic photovoltaic devices induced by incorporating Al, Ag, and Au nanoparticles in the active layer. We find that Al nanoparticles should yield significantly greater enhancement ... 
An analysis of nonoblique corrections to the Zb¯b vertex
(1994)We present a model–independent analysis of the Zb¯b vertex, with the aim of constraining contributions of new physics to the left and right–handed couplings of the b. We find that the left–handed coupling of the b is quite ... 
Analysis of optical response of long period fiber gratings to nmthick thinfilm coatings
(Optical Society of America, 20050401)We have theoretically and experimentally demonstrated that the resonant wavelength of long period fiber gratings (LPG) can be shifted by a large magnitude by coating with only a nmthickthinfilm that has a refractive index ... 
An analysis of Precision Electroweak Measurements: Summer 98 Update
We update our analysis of precision electroweak measurements using the latest data announced at Moriond, March 1998. Possible oblique corrections from new physics are parametrized using the STU formalism of Ref.[1], and ...
