  • Bubis, Roy; Kantor, Yacov; Kardar, Mehran (IOP Publishing, 2009-11)
    We study polymers attached to spherical (circular) or paraboloidal (parabolic) probes in three (two) dimensions. Both self-avoiding and random walks are examined numerically. The behavior of a polymer of size R[subscript ...
  • Gorsky, A.; Shifman, Mikhail; Yung, A. (American Physical Society, 2011-04)
    Non-Abelian strings exist in the color-flavor locked phase of dense QCD. We show that kinks appearing in the world-sheet theory on these strings, in the form of the kink-antikink bound pairs, are the magnetic monopoles—descendants ...
  • Alpichshev, Zhanybek; Mahmood, Fahad; Cao, Gang; Gedik, Nuh (American Physical Society, 2015-01)
    We use ultrafast optical spectroscopy to observe binding of charged single-particle excitations (SE) in the magnetically frustrated Mott insulator Na[subscript 2]IrO[subscript 3]. Above the antiferromagnetic ordering ...
  • Nishida, Yusuke; Tan, Shina (American Physical Society, 2009-06)
    A Fermi-Fermi mixture of 40K and 6Li does not exhibit the Efimov effect in a free space, but the Efimov effect can be induced by confining only 40K in one dimension. Here the Efimov’s three-body parameter is controlled by ...
  • Nishida, Yusuke; Tan, Shina (American Physical Society, 2010-12)
    We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-wave resonances in mixed dimensions. We develop two-body scattering theories in all three cases of 0D-3D, 1D-3D, and 2D-3D mixtures ...
  • Spokoini, Rachel; Moldavski, Ofer; Nahmias, Yaakov; England, Jeremy L.; Schuldiner, Maya; Kaganovich, Daniel (Elsevier, 2012-09)
    The division of the S. cerevisiae budding yeast, which produces one mother cell and one daughter cell, is asymmetric with respect to aging. Remarkably, the asymmetry of yeast aging coincides with asymmetric inheritance of ...
  • Bellm, Eric C.; Pottschmidt, Katja; Tomsick, John A.; Boggs, Steven E.; Chakrabarty, Deepto; Christensen, Finn E.; Craig, William W.; Hailey, Charles J.; Harrison, Fiona A.; Stern, Daniel; Walton, Dominic J.; Zhang, William W.; Chakrabarty, Deepto; Furst, Felix; Wilms, Jorn (IOP Publishing, 2014-08)
    GRO J1008–57 is a high-mass X-ray binary for which several claims of a cyclotron resonance scattering feature near 80 keV have been reported. We use NuSTAR, Suzaku, and Swift data from its giant outburst of 2012 November ...
  • Bayliss, Daniel D. R.; Winn, Joshua Nathan; Mardling, Rosemary A.; Sackett, Penny D. (Institute of Physics, 2010-10)
    We present high-precision radial velocity observations of WASP-17 throughout the transit of its close-in giant planet, using the MIKE spectrograph on the 6.5 m Magellan Telescope at Las Campanas Observatory. By modeling ...
  • Quintana, Elisa V.; Rowe, Jason F.; Barclay, Thomas; Howell, Steve B.; Ciardi, David R.; Demory, Brice-Olivier; Caldwell, Douglas A.; Borucki, William J.; Christiansen, Jessie L.; Jenkins, Jon M.; Klaus, Todd C.; Fulton, Benjamin J.; Morris, Robert L.; Sanderfer, Dwight T.; Shporer, Avi; Smith, Jeffrey C.; Still, Martin; Thompson, Susan E. (IOP Publishing, 2013-04)
    We present high precision photometry of Kepler-41, a giant planet in a 1.86 day orbit around a G6V star that was recently confirmed through radial velocity measurements. We have developed a new method to confirm giant ...
  • Fang, Taotao; Buote, David A.; Humphrey, Philip J.; Canizares, Claude R.; Zappacosta, Luca; Maiolino, Roberto; Tagliferri, Gianpiero; Gastaldello, Fabio (IOP Publishing, 2010-04)
    In a previous paper, we reported a 3σ detection of an absorption line from the warm-hot intergalactic medium (WHIM) using the Chandra and XMM X-ray grating spectra of the blazar H2356-309, the sight line of which intercepts ...
  • Gou, Lijun; McClintock, Jeffrey E.; Remillard, Ronald Alan; Steiner, James F.; Reid, Mark J.; Orosz, Jerome A.; Narayan, Ramesh; Hanke, Manfred; García, Javier (Institute of Physics/American Astronomical Society, 2014-07)
    In Gou et al., we reported that the black hole primary in the X-ray binary Cygnus X-1 is a near-extreme Kerr black hole with a spin parameter a * > 0.95 (3σ). We confirm this result while setting a new and more stringent ...
  • Fang, Taotao; Canizares, Claude R.; Yao, Yangsen (IOP Publishing, 2007-08)
    We present new observations of PKS 2155-304 with the Chandra Low Energy Transmission Grating (LETG), using the Advanced CCD Imaging Spectrometer (ACIS). We confirm the detection of an absorption line plausibly identified ...
  • Jackiw, Roman; Pi, So-Young (American Physical Society, 2012-08)
    Extending previous work on two- and three-point functions, we study the four-point function and its conformal block structure in conformal quantum mechanics CFT[subscript 1], which realizes the SO(2,1) symmetry group. ...
  • Chesler, Paul; Lucas, Andrew; Sachdev, Subir (American Physical Society, 2014-01)
    We study (2+1)-dimensional conformal field theories (CFTs) with a globally conserved U(1) charge, placed in a chemical potential which is periodically modulated along the spatial direction x with zero average: μ(x)=V cos(kx). ...
  • Swingle, Brian Gordon (American Physical Society, 2012-07)
    The Fermi surface may be usefully viewed as a collection of (1+1)-dimensional chiral conformal field theories. This approach permits straightforward calculation of many anomalous ground-state properties of the Fermi gas, ...
  • Bimonte, G.; Emig, T.; Kardar, Mehran (Institute of Physics Publishing, 2013-10)
    Thermal fluctuations of a critical system induce long-ranged Casimir forces between objects that couple to the underlying field. For two-dimensional (2D) conformal field theories (CFT) we derive an exact result for the ...
  • Larkoski, Andrew James (American Physical Society, 2014-10)
    In this note, I show that the recently proposed subleading soft factor in massless gauge theory uniquely follows from conformal symmetry of tree-level gauge theory amplitudes in four dimensions.
  • Werner, Wendelin; Sheffield, Scott Roger (Princeton University Press, 2012-11)
    For random collections of self-avoiding loops in two-dimensional domains, we define a simple and natural conformal restriction property that is conjecturally satisfied by the scaling limits of interfaces in models from ...
  • Anninos, Dionysios; Anous, Tarek; de Lange, Paul; Konstantinidis, George (Springer-Verlag/International School for Advanced Studies (SISSA), 2015-03)
    Quiver quantum mechanics describes the low energy dynamics of a system of wrapped D-branes. It captures several aspects of single and multicentered BPS black hole geometries in four-dimensional N = 2 supergravity such as ...
  • Kaiser, David I. (American Physical Society, 2010-04)
    Many interesting models incorporate scalar fields with nonminimal couplings to the spacetime Ricci curvature scalar. As is well known, if only one scalar field is nonminimally coupled, then one may perform a conformal ...
