Pair contact process with diffusion: Failure of master equation field theory
(American Physical Society, 200411)We demonstrate that the "microscopic" field theory representation, directly derived from the corresponding master equation, fails to adequately capture the continuous nonequilibrium phase transition of the pair contact ... 
Pair contact process with diffusion: Failure of master equation field theory

Parallel Temperature Interfaces in the KatzLebowitzSpohn Driven Lattice Gas
We explore a variant of the KatzLebowitzSpohn (KLS) driven lattice gas in two dimensions, where the lattice is split into two regions that are coupled to heat baths with distinct temperatures. The temperature boundaries ... 
Pathintegral approach to the Hubbard model
(American Physical Society, 199102)A pathintegral approach to the Hubbard model is developed for the whole range of the coupling strength U. At half filling, the strongcoupling results are readily reproduced within the simple Gaussian fluctuations. The ... 
Pattern recognition with wavelengthmultiplexed filters
(Optical Society of America, 197908)Wavelengthmultiplexed matched spatial filters are used in an incoherent optical pattern recognition system. The system produces colorcoded correlation responses which allow the simultaneous recognition of several objects ... 
Percolationenhanced supersolids in the extended BoseHubbard model
(American Physical Society, 20120104)We theoretically study the stability of lattice supersolid states in the extended BoseHubbard model with bounded spatial disorder. We construct a disorder meanfield theory and compare with quantum Monte Carlo calculations. ...

Performance of the Los Alamos National Laboratory spallationdriven soliddeuterium ultracold neutron source
(AIP Publishing, 201301)In this paper, we describe the performance of the Los Alamos spallationdriven soliddeuterium ultracold neutron (UCN) source. Measurements of the cold neutron flux, the very low energy neutron production rate, and the ... 
Perspectives on clinical informatics: integrating largescale clinical, genomic, and health information for clinical care.
(201312)The advances in electronic medical records (EMRs) and bioinformatics (BI) represent two significant trends in healthcare. The widespread adoption of EMR systems and the completion of the Human Genome Project developed the ...

Phase Transitions and Scaling in Systems Far From Equilibrium
Scaling ideas and renormalization group approaches proved crucial for a deep understanding and classification of critical phenomena in thermal equilibrium. Over the past decades, these powerful conceptual and mathematical ...

Phenomenology of aging in the KardarParisiZhang equation
(American Physical Society, 20120327)We study aging during surface growth processes described by the onedimensional KardarParisiZhang equation. Starting from a flat initial state, the systems undergo simple aging in both correlators and linear responses, ... 
Phenomenology of Notsoheavy Neutral Leptons: The NuTeV Anomaly, Lepton Universality, and NonUniversal NeutrinoGauge Couplings
Talk presented by Takeuchi at the YITP workshop "Progress in Particle Physics" 2004. 
Photogeneration action spectroscopy of neutral and charged excitations in films of a laddertype poly(paraphenylene)
(American Physical Society, 19990419)The photogeneration quantum efficiency action spectra of longlived neutral and charged excitations in films of a laddertype poly(paraphenylene) were measured. We found that both tripler and polaron action spectra show, ... 
Photogeneration and recombination processes of neutral and charged excitations in films of a laddertype poly(paraphenylene)
(American Physical Society, 19990815)We introduce a version of the cw photomodulation technique, measured far from the steady state, for obtaining the quantum efficiency, eta, of longlived photoexcitations in piconjugated polymers. We apply this technique ... 
Photoinduced spinpolarized current in InSbbased structures
(American Institute of Physics, 20091115)We demonstrate the observation of spinpolarized photocurrent in InSb films grown on GaAs and InP substrates and InSb quantum wells where a nonequilibrium spin population has been achieved by using circularly polarized ... 
Photoluminescence lineshape and dynamics of localized excitonic transitions in InAsP epitaxial layers
(American Institute of Physics, 20140521)The excitonic radiative transitions of InAsxP1x (x = 0.13 and x = 0.40) alloy epitaxial layers were studied through magnetic field and temperature dependent photoluminescence and timeresolved photoluminescence spectroscopy. ...
