  • Joannopoulos, John D.; McCauley, Alexander Patrick; Johnson, Steven G.; Rodriguez, Alejandro W. (American Physical Society, 2009-07)
    We present a method to compute Casimir forces in arbitrary geometries and for arbitrary materials based on the finite-difference time-domain (FDTD) scheme. The method involves the time evolution of electric and magnetic ...
  • Rodriguez, Alejandro W.; McCauley, Alexander Patrick; Joannopoulos, John D.; Johnson, Steven G. (American Physical Society, 2009-07)
    We present a method to compute Casimir forces in arbitrary geometries and for arbitrary materials based on the finite-difference time-domain (FDTD) scheme. The method involves the time evolution of electric and magnetic ...
  • Nishida, Yusuke (American Physical Society, 2009-01)
    We investigate a two-species Fermi gas with a large mass ratio interacting by an interspecies short-range interaction. Using the Born-Oppenheimer approximation, we determine the interaction energy of two heavy fermions ...
  • Zaheer, Saad; Rahi, Sahand Jamal; Emig, Thorsten; Jaffe, Robert L. (American Physical Society, 2010-03)
    We investigate the electromagnetic Casimir interactions of an object contained within an otherwise empty, perfectly conducting spherical shell. For a small object we present analytical calculations of the force, which is ...
  • Varela, Jaime; Rodriguez, Alejandro W.; McCauley, Alexander Patrick; Johnson, Steven G. (American Physical Society, 2011-04)
    Our previous paper [Phys. Rev. Lett. 104, 060401 (2010)] predicted that Casimir forces induced by the material-dispersion properties of certain dielectrics can give rise to stable configurations of objects. This phenomenon ...
  • Bimonte, Giuseppe; Emig, Thorsten; Kardar, Mehran (American Physical Society, 2015-07)
    The Casimir-Polder interaction between an anisotropic particle and a surface is orientation dependent. We study novel orientational effects that arise due to curvature of the surface for distances much smaller than the ...
  • Bimonte, Giuseppe; Emig, Thorsten; Kardar, Mehran (American Physical Society, 2014-10)
    We use a derivative expansion for gently curved surfaces to compute the leading and the next-to-leading curvature corrections to the Casimir-Polder interaction between a polarizable small particle and a nonplanar surface. ...
  • Zaheer, Saad; Rahi, Sahand Jamal; Emig, Thorsten; Jaffe, Robert L. (American Physical Society, 2010-11)
    We study the electromagnetic Casimir interaction of a compact object contained inside a closed cavity of another compact object. We express the interaction energy in terms of the objects’ scattering matrices and translation ...
  • Levin, Michael; McCauley, Alexander Patrick; Rodriguez, Alejandro W.; Reid, M. T. Homer; Johnson, Steven G. (American Physical Society, 2010-08)
    We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole. We prove that ...
  • Oliver, Trudy; Meylan, Etienne; Chang, Gregory P.; Xue, Wen; Burke, James R.; Humpton, Timothy J.; Hubbard, Diana D.; Bhutkar, Arjun (AJ); Jacks, Tyler E. (Elsevier, 2011-07)
    Caspase-2 is an evolutionarily conserved caspase, yet its biological function and cleavage targets are poorly understood. Caspase-2 is activated by the p53 target gene product PIDD (also known as LRDD) in a complex called ...
  • Li, Zheng; Jo, Jihoon; Jia, Jie-Min; Lo, Shih-Ching; Whitcomb, Daniel J.; Jiao, Song; Cho, Kwangwook; Sheng, Morgan (Elsevier, 2010-05)
    NMDA receptor-dependent synaptic modifications, such as long-term potentiation (LTP) and long-term depression (LTD), are essential for brain development and function. LTD occurs mainly by the removal of AMPA receptors from ...
  • Sun, Wei; Boulais, Etienne; Hakobyan, Yera; Wang, Wei Li; Guan, Amy; Bathe, Mark; Yin, Peng (American Association for the Advancement of Science (AAAS), 2014-10)
    We report a general strategy for designing and synthesizing inorganic nanostructures with arbitrarily prescribed three-dimensional shapes. Computationally designed DNA strands self-assemble into a stiff “nanomold” that ...
  • Szkody, Paula; Anderson, Scott F.; Hayden, Michael; Kronberg, Martin; McGurk, Rosalie; Riecken, Thomas; Schmidt, Gary D.; West, Andrew A.; Gansicke, Boris T.; Gomez-Moran, Ada N.; Schneider, Donald P.; Schreiber, Matthias R.; Schwope, Axel D. (IOP Publishing, 2009-03)
    Coordinates, magnitudes, and spectra are presented for 39 cataclysmic variables (CVs) found in Sloan Digital Sky Survey (SDSS) spectra that were primarily obtained in 2006. Of these, 13 were CVs identified prior to the ...
  • Muno, Michael P.; Bauer, Franz E.; Bandyopadhyay, R. M.; Bower, Geoffrey C.; Brandt, W. N.; Broos, P. S.; Cotera, A.; Eikenberry, S. S.; Garmire, Gordon P.; Hyman, S. D.; Kassim, N. E.; Lang, C. C.; Lazio, T. Joseph W.; Law, J. C.; Mauerhan, Jon C.; Morris, M. R.; Nagata, T.; Nishiyama, S.; Park, S.; Ramìrez, S. V.; Stolovy, S. R.; Wijnands, R.; Wang, Q. D.; Wang, Z.; Yusef-Zadeh, F.; Baganoff, Frederick K. (IOP Publishing, 2009-03)
    We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2°× 0°.8 field around the Galactic center. This enlarges the number of known X-ray sources in the region by a factor of 2.5. The catalog ...
  • Ueda, Satoshi; Buchwald, Stephen Leffler (Wiley Blackwell, 2012-09)
    What N would you like? The chemoselective and complementary Pd- and Cu-catalyzed N-arylation of 2-aminobenzimidazoles is described. Selective N-arylation of the amino group was achieved with a Pd-catalyzed method, while ...
  • Yu, Miao; Schrock, Richard Royce; Hoveyda, Amir H. (John Wiley & Sons, 2014-11)
    Molybdenum-, tungsten-, and ruthenium-based complexes that control the stereochemical outcome of olefin metathesis reactions have been recently introduced. However, the complementary nature of these systems through their ...

    T cell activation by antigens binding to the T cell receptor (TCR) must be properly regulated to ensure normal T cell development and effective immune responses to pathogens and transformed cells while avoiding autoimmunity. ...
  • Ho, Chun-Yu; Chan, Chun-Wa; Schleicher, Kristin D.; Jamison, Timothy F. (Thieme Publishing Group, 2009-09)
    Recent advances using nickel complexes in the activation of unactivated monosubstituted olefins for catalytic intermolecular carbon-carbon bond-forming reactions with carbonyl compounds, such as simple aldehydes, isocyanates, ...

    Catalytic assembly of enantiopure aliphatic amines from abundant and readily available precursors has long been recognized as a paramount challenge in synthetic chemistry. Here, we describe a mild and general copper-catalyzed ...
