Circle-valued Morse theory for complex hyperplane arrangements

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 […]

Digital Plasmonics

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Bergin Gjonaj, Jochen Aulbach, Patrick M. Johnson, Allard P. Mosk, Kobus Kuipers | Summary: The field of plasmonics offers a route to control light fields with metallic nanostructures through the excitation of Surface Plasmon Polaritons (SPPs). These surface waves, bound to a metal dielectric interface, tightly confine […]

The shrinking instability of toroidal liquid droplets in the Stokes flow regime

Kavli Affiliate: Mark Bowick | First 5 Authors: Zhenwei Yao, Mark Bowick, , , | Summary: We analyze the stability and dynamics of toroidal liquid droplets. In addition to the Rayleigh instabilities akin to those of a cylindrical droplet there is a shrinking instability that is unique to the topology of the torus and dominates […]

DFT-based many-body analysis of electron transport through molecules

Kavli Affiliate: Joseph M. Thijssen | First 5 Authors: Fatemeh Mirjani, Joseph M. Thijssen, , , | Summary: We present a method which uses density functional theory (DFT) to treat transport through a single molecule connected to two conducting leads for the weak and intermediate coupling. This case is not accessible to standard non-equilibrium Green’s […]

Probing dark energy and neutrino mass from upcoming lensing experiments of CMB and galaxies

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, […]

Surface Photometry and Radial Color Gradients of Nearby Luminous Early-type Galaxies in SDSS Stripe 82

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 […]

Investigating reciprocity failure in 1.7-micron cut-off HgCdTe detectors

Kavli Affiliate: Tomasz Biesiadzinski | First 5 Authors: Michael Schubnell, Tomasz Biesiadzinski, Wolfgang Lorenzon, Robert Newman, Greg Tarle | Summary: Flux dependent non-linearity (reciprocity failure) in HgCdTe NIR detectors with 1.7 micron cut-off was investigated. A dedicated test station was designed and built to measure reciprocity failure over the full dynamic range of near infrared […]
