Validating quantumclassical programming models with tensor network simulations
(PLOS, 20181210)The exploration of hybrid quantumclassical algorithms and programming models on noisy nearterm quantum hardware has begun. As hybrid programs scale towards classical intractability, validation and benchmarking are critical ... 
Variational and nonvariational principles in quantum transport calculations
(American Physical Society, 200207)A variational principle is not generally satisfied in steadystate quantum transport as opposed to the case of groundstate problems. We show that for a shortrange potential, a functional for the scattering amplitude can ... 
Variational ground state for the periodic Anderson model
(American Institute of Physics, 19880415)A variational calculation of the ground state of the Anderson lattice model is discussed. The calculation creates a finite Hamiltonian matrix for many_electron states, which are appropriate for the thermodynamic limit. A ... 
Variational study of the spingap phase of the onedimensional tJ model
(American Physical Society, 19961001)We propose a correlated spinsingletpair wave function to describe the spingap phase of the onedimensional tJ model at low density and large J/t. In addition to having singlet pairs, this wave function has a Jastrow ... 
Viability of competing field theories for the driven lattice gas
(American Physical Society, 200005)It has recently been suggested that the driven lattice gas should be described by an alternate held theory in the limit of infinite drive. We review the original and the alternate field theory, invoking several welldocumented ... 
Viability of competing field theories for the driven lattice gas

Vlasov theory of plasma oscillations: linearapproximation
(AIP Publishing, 1977)A functional analytic approach to the linearized collisionless Vlasov equation is presented utilizing a resolvent integration technique on the resolvent of the transport operator evaluated at a particular point. Formulae ... 
Volume holograms constructed from computergenerated masks
(Optical Society of America, 197805)A new type of hologram that combines computergenerated holograms with volume holograms is described. This hologram allows arbitrary selection of the location and color of a computergenerated image when white light ... 
Vortex transport and voltage noise in disordered superconductors
(Elsevier Science Bv, 20030201)We study, by means of threedimensional Monte Carlo simulations, the current–voltage (I–V) characteristics and the voltage noise spectrum at low temperatures of driven magnetic flux lines interacting with randomly placed ... 
Vortex washboard voltage noise in typeII superconductors
(Springer, 20081001) 
The W mass and the U parameter

Waterpollution monitoring using matched spatial filters
(Optical Society of America, 197602)Presented are some results obtained from the application of matched spatial filtering techniques to the identification of biological specimens called diatoms (i.e., water algae). A prototype semiautomatic optical processor ... 
Wavefunction vortex attachment via matrix products: Application to atomic Fermi gases in flat spinorbit bands
(Amer Physical Soc, 20140331) 
Weak hard Xray emission from two broad absorption line quasars observed with NuSTAR: Comptonthick absorption or intrinsic Xray weakness?
(IOP Publishing Ltd., 201308)We present Nuclear Spectroscopic Telescope Array (NuSTAR) hard Xray observations of two Xray weak broad absorption line (BAL) quasars, PG 1004+130 (radio loud) and PG 1700+518 (radio quiet). Many BAL quasars appear Xray ... 
Why doublestranded RNA resists condensation
(20140915)The addition of small amounts of multivalent cations to solutions containing doublestranded DNA leads to interDNA attraction and eventual condensation. Surprisingly, the condensation is suppressed in doublestranded RNA, ... 
Wilson lines and ChernSimons flux in explicit heterotic CalabiYau compactifications
(Springer, 20150227)We study to what extent Wilson lines in heterotic CalabiYau compactifications lead to nontrivial Hflux via ChernSimons terms. Wilson lines are basic ingredients for Standard Model constructions but their induced Hflux ... 
WISE detections of known QSOs at redshifts greater than six
(IOP Publishing Ltd., 201312)We present WISE AllSky midinfrared (IR) survey detections of 55% (17/31) of the known QSOs at z > 6 from a range of surveys: the SDSS, the CFHTLS, FIRST, Spitzer, and UKIDSS. The WISE catalog thus provides a substantial ... 
Witten index for noncompact dynamics
(Springer, 20160616)Among gauged dynamics motivated by string theory, we find many with gapless asymptotic directions. Although the natural boundary condition for ground states is L2, one often turns on chemical potentials or supersymmetric ... 
Wulff shapes and the critical nucleus for a triangular Ising lattice
(American Physical Society, 200102)Equilibrium Wulff shapes and interfacial energies of twodimensional "crystals" on a triangular lattice are considered. Asymptotic approximations are constructed for both the shapes and energies in the limit T>0 where ...
