Search for anomalous top quark couplings with the D0 detector
D0 Collaboration, V. Abazov
Anomalous Wtb couplings modify the angular correlations of the top quark decay products and change the single top quark production cross section. We present limits on anomalous top…
Modulation of Electrical Conduction Through Individual Molecules on Silicon by the Electrostatic Fields of Nearby Polar Molecules: Theory and Experiment
George Kirczenow, Paul G. Piva, Robert A. Wolkow
We report on the synthesis, scanning tunneling microscopy (STM) and theoretical modeling of the electrostatic and transport properties of one-dimensional organic heterostructures c…
On the existence of a static black hole on a brane
Hirotaka Yoshino
We study a static black hole localized on a brane in the Randall-Sundrum (RS) II braneworld scenario. To solve this problem numerically, we develop a code having the almost 4th-ord…
The SU(N) Heisenberg model on the square lattice: a continuous-N quantum Monte Carlo study
K. S. D. Beach, Fabien Alet, Matthieu Mambrini +1
A quantum phase transition is typically induced by tuning an external parameter that appears as a coupling constant in the Hamiltonian. Another route is to vary the global symmetry…
Disorder-induced superfluidity
Long Dang, Massimo Boninsegni, Lode Pollet
We use quantum Monte Carlo simulations to study the phase diagram of hard-core bosons with short-ranged {\it attractive} interactions, in the presence of uniform diagonal disorder.…
Partially Unbiased Entangled Bases
A. Kalev, F. C. Khanna, M. Revzen
In this contribution we group the operator basis for d^2 dimensional Hilbert space in a way that enables us to relate bases of entangled states with single particle mutually unbias…
Preduals of semigroup algebras
Matthew Daws, Hung Le Pham, Stuart White
For a locally compact group , the measure convolution algebra carries a natural coproduct. In previous work, we showed that the canonical predual of is th…
The Majorana Neutrinoless Double-Beta Decay Experiment
V. E. Guiseppe
Neutrinoless double-beta decay searches play a major role in determining the nature of neutrinos, the existence of a lepton violating process, and the effective Majorana neutrino m…
The Local Theory of the Cosmic Skeleton
D. Pogosyan, C. Pichon, C. Gay +4
The local theory of the critical lines of 2D and 3D Gaussian fields that underline the cosmic structures is presented. In the context of cosmological matter distribution the subset…
A continuous model for microtubule dynamics with catastrophe, rescue and nucleation processes
Peter Hinow, Vahid Rezania, Jack A. Tuszynski
Microtubules are a major component of the cytoskeleton distinguished by highly dynamic behavior both in vitro and in vivo. We propose a general mathematical model that accounts for…
Evidence for the decay B_s^0 --> D_s^(*)D_s^(*) and a measurement of Delta_Gamma_s^CP/Gamma_s
D0 Collaboration, V. M. Abazov
We search for the semi-inclusive process B_s^0 --> D_s^(*)D_s^(*) using 2.8 fb^-1 of ppbar collisions at s^(1/2) = 1.96 TeV recorded by the D0 detector operating at the Fermilab Te…
Exploring a new peak in the heterotic landscape
Anthony Bak, Vincent Bouchard, Ron Donagi
We study the existence of realistic heterotic vacua on a new Abelian surface fibered Calabi-Yau threefold X with Z_8 x Z_8 fundamental group. Our main result is a no-go theorem, wh…
Search for the lightest scalar top quark in events with two leptons in ppbar collisions at sqrt(s)=1.96 TeV
D0 Collaboration, V. Abazov
We report results of a search for the pair production of the lightest supersymmetric partner of the top quark using 1 fb-1 of data collected by the D0 detector at a ppbar center-of…
Search for neutral Higgs bosons at high tan(beta) in the b(h/H/A)->btautau channel
D0 Collaboration, V. Abazov
The first search in ppbar collisions at sqrt(s)=1.96 GeV for the production of neutral Higgs bosons in association with bottom quarks and decaying in two tau leptons is presented.…
Parallel-propagated frame along null geodesics in higher-dimensional black hole spacetimes
David Kubiznak, Valeri P. Frolov, Pavel Krtous +1
In [arXiv:0803.3259] the equations describing the parallel transport of orthonormal frames along timelike (spacelike) geodesics in a spacetime admitting a non-degenerate principal…
A proposal for studying off-shell stability of vacuum geometries in string theory
V. Suneeta
We briefly review studies of off-shell stability of vacuum geometries in semiclassical gravity. We propose a study of off-shell stability of vacua in string theory by a distinct, t…
The shape of disorder broadened Landau subbands in graphene
W. Zhu, Q. W. Shi, X. R. Wang +2
Density of states (DOS) of graphene under a high uniform magnetic field and white-noise random potential is numerically calculated. The disorder broadened zero-energy Landau band h…
A first principle (3+1) dimensional model for microtubule polymerization
Vahid Rezania, Jack Tuszynski
In this paper we propose a microscopic model to study the polymerization of microtubules (MTs). Starting from fundamental reactions during MT's assembly and disassembly processes,…
The Discovery of a Very Faint X-ray Transient in the Globular Cluster M15
Craig O. Heinke, Haldan N. Cohn, Phyllis M. Lugger
We have identified an X-ray transient (hereafter M15 X-3) in the globular cluster M15 from an archival Chandra grating observation. M15 X-3 appears at an X-ray luminosity of 6*10^{…
