Probing Spatial Spin Correlations of Ultracold Gases by Quantum Noise Spectroscopy
(American Physical Society, 2009)Spin noise spectroscopy with a single laser beam is demonstrated theoretically to provide a direct probe of the spatial correlations of cold fermionic gases. We show how the generic many-body phenomena of anti-bunching, ... -
Probing surface charge fluctuations with solid-state nanopores
(American Physical Society, 2009)We identify a contribution to the ionic current noise spectrum in solid-state nanopores that exceeds all other noise sources in the frequency band 0.1-10 kHz. Experimental studies of the dependence of this excess noise on ... -
Probing the epoch of reionization with Milky Way satellites
(Oxford University Press, 2009)While the connection between high-redshift star formation and the local Universe has recently been used to understand the observed population of faint dwarf galaxies in the Milky Way (MW) halo, we explore how well these ... -
Probing the Epoch of Reionization with the Lyα Forest at Z ∼ 4-5
(American Astronomical Society, 2009) -
Probing the Foundations of Tully's Public Philosophy
(SAGE Publications, 2011)James Tully’s Public Philosophy in a New Key is a complex intellectual edifice. Tully deftly deploys the philosophical tools forged by, among others, Wittgenstein, Arendt, Foucault, and Skinner to dismantle the architecture ... -
Probing the gaseous halo of galaxies through non-thermal emission from AGN-driven outflows
(Oxford University Press, 2015)Feedback from outflows driven by active galactic nuclei (AGN) can affect the distribution and properties of the gaseous haloes of galaxies. We study the hydrodynamics and non-thermal emission from the forward outflow shock ... -
Probing the Magnetic Field at Subparsec Radii in the Accretion Disk of NGC 4258
(IOP Publishing, 2005)We present an analysis of polarimetric observations at 22 GHz of the water vapor masers in NGC 4258 obtained with the VLA and the GBT. We do not detect any circular polarization in the spectrum indicative of Zeeman-induced ... -
Probing the Magnetic Field Structure in Gamma‐Ray Bursts through Dispersive Plasma Effects on the Afterglow Polarization
(American Astronomical Society, 2004)The origin and structure of magnetic fields in gamma-ray burst (GRB) fireball plasmas are two of the most important open questions in all GRB models. It has been claimed that recent measurements of gamma-ray polarization ... -
Probing the Mass Fraction of MACHOs in Extragalactic Halos
(American Astronomical Society, 1998)Current microlensing searches calibrate the mass fraction of the Milky Way halo that is in the form of massive astrophysical compact halo objects (MACHOs). We show that surveys like the Sloan Digital Sky Survey (SDSS) can ... -
Probing the neutral fraction of the IGM with GRBs during the epoch of reionization
(Oxford University Press, 2008-07-25)We show that near-infrared observations of the red side of the Ly alpha line from a single gamma-ray burst (GRB) afterglow cannot be used to constrain the global neutral fraction of the intergalactic medium (IGM), (x) over ... -
Probing the Onset of Quantum Avalanches in a Many-Body Localized System
(Springer Science and Business Media LLC, 2023-01-26)Strongly correlated systems can exhibit unexpected phenomena when brought in a state far from equilibrium. An example is many-body localization, which prevents generic interacting systems from reaching thermal equilibrium ... -
Probing the Spacetime around Sagittarius A* with Radio Pulsars
(American Astronomical Society, 2004)The supermassive black hole at the Galactic center harbors a bound cluster of massive stars that should leave neutron star remnants. Extrapolating from the available data, we estimate that similar to1000 radio pulsars may ... -
Probing the spacetime around supermassive black holes with ejected plasma blobs
(American Physical Society, 2015)Millimeter-wavelength very-long-baseline-interferometry observations of the supermassive black holes in Sgr A* and M87 by the Event Horizon Telescope could potentially trace the dynamics of ejected plasma blobs in real ... -
Probing the Superfluid to Mott Insulator Transition at the Single Atom Level
(American Association for the Advancement of Science, 2010)Quantum gases in optical lattices offer an opportunity to experimentally realize and explore condensed matter models in a clean, tunable system. We used single atom–single lattice site imaging to investigate the Bose-Hubbard ... -
Probing the Universe after Cosmological Recombination through the Effect of Neutral Lithium on the Microwave Background Anisotropies
(American Astronomical Society, 2001)I show that neutral lithium couples strongly to the cosmic microwave background (CMB) through its 6708 Angstrom resonant transition after it recombines at z similar to 500. At observed wavelengths of less than or similar ... -
Probing the Wtb vertex structure in t-channel single-top-quark production and decay in pp collisions at s√=8 TeV with the ATLAS detector
(Springer Nature, 2017)To probe the Wtb vertex structure, top-quark and W-boson polarisation observables are measured from t-channel single-top-quark events produced in proton--proton collisions at a centre-of-mass energy of 8 TeV. The dataset ... -
A problem in theory
(Springer Science and Business Media LLC, 2019-02-11)A growing body of evidence suggests that humans are a new kind of animal—a product of genetic information from our parents and cultural information from our societies. This “Dual Inheritance Theory”, grounded in the ... -
