Kavli Affiliate: John W. Belcher | First 5 Authors: Stanislaw Olbert, John W. Belcher, Richard H. Price, , | Summary: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we find that our solutions for these fields […]
Kavli Affiliate: Austin Joyce | First 5 Authors: Austin Joyce, Justin Khoury, , , | Summary: For a single scalar field with unit sound speed minimally coupled to Einstein gravity, there are exactly three distinct cosmological solutions which produce a scale invariant spectrum of curvature perturbations in a dynamical attractor background, assuming vacuum initial conditions: […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Jeffrey M. McMahon, David M. Ceperley, , , | Summary: Superconductivity in the recently proposed ground-state structures of atomic metallic hydrogen is investigated over the pressure range 500 GPa to 3.5 TPa. Near molecular dissociation, the electron–phonon coupling $λ$ and renormalized Coulomb repulsion are similar to the […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Jeffrey M. McMahon, , , , | Summary: textit{Ab initio} random structure searching based on density functional theory is used to determine the ground-state structures of ice at high pressures. Including estimates of lattice zero-point energies, ice is found to adopt three novel crystal phases. The underlying […]
Kavli Affiliate: Atsushi Yagishita | First 5 Authors: Kentaro Tanaka, Atsushi Yagishita, Masami Miyakawa, , | Summary: For a given statistical model, it often happens that it is necessary to intervene the model to reduce the variances of the output variables. In structural equation models, this can be done by changing the values of the […]
Kavli Affiliate: Jonathan Rosner | First 5 Authors: Jonathan L. Rosner, , , , | Summary: The reaction $e^+ e^- to (D_s^{*+} D_s^- + {rm c.c.})$ has been used with great success at the CLEO-c detector, and will be a source of valuable future data from the BES-III detector, to obtain information about the properties […]
Kavli Affiliate: Toshitake Kohno | First 5 Authors: Toshitake Kohno, Andrei Pajitnov, , , | Summary: Let A be an essential complex hyperplane arrangement in an n-dimensional complex vector space V. Let H denote the union of the hyperplanes, and M denote the complement to H in V. We develop the real-valued and circle-valued Morse […]
Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Jinyi Shangguan, Huirong Yan, , , | Summary: We demonstrate a new way of studying interplanetary magnetic field — Ground State Alignment (GSA). Instead of sending thousands of space probes, GSA allows magnetic mapping with any ground telescope facilities equipped with spectropolarimeter. The polarization of spectral lines […]
Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Toshiya Namikawa, Shun Saito, Atsushi Taruya, , | Summary: We discuss the synergy of the cosmic shear and CMB lensing experiments to simultaneously constrain the neutrino mass and dark energy properties. Taking fully account of the CMB lensing, cosmic shear, CMB anisotropies, and their cross correlation signals, […]
Fangzhou Jiang, Song Huang, Qiusheng Gu, , | Summary: [[{“value”:”We make use of the images from the Sloan Digital Sky Survey Stripe 82 to present an analysis of r band surface brightness profiles and radial color gradients (g – r, u – r) in 111 nearby early-type galaxies (ETGs). With Stripe 82 images, we are […]
