Measuring the spatial extent of individual localized photonic states

Kavli Affiliate: Kobus Kuipers | First 5 Authors: Marko Spasenovic, Daryl M. Beggs, Philippe Lalanne, Thomas F. Krauss, L. | Summary: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with […]

A photonic crystal nanocavity laser in an optically very thick slab

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Jingqing Huang, Axel Scherer, , | Summary: A photonic crystal (PhC) nanocavity formed in an optically very thick slab can support reasonably high-Q modes for lasing. Experimentally, we demonstrate room-temperature pulsed lasing operation from the PhC dipole mode emitting at 1324 nm, which is fabricated […]

Suzaku Observations of 4U 1957+11: Potentially the Most Rapidly Spinning Black Hole in (the Halo of) the Galaxy

Kavli Affiliate: Norbert Schulz | First 5 Authors: Michael A. Nowak, Joern Wilms, Katja Pottschmidt, Norbert Schulz, Dipankar Maitra | Summary: We present three Suzaku observations of the black hole candidate 4U 1957+11 (V1408 Aql) — a source that exhibits some of the simplest and cleanest examples of soft, disk-dominated spectra. 4U 1957+11 also presents […]

Ion association in low-polarity solvents: comparisons between theory, simulation, and experiment

Kavli Affiliate: Jos W. Zwanikken | First 5 Authors: Chantal Valeriani, Philip J. Camp, Jos W. Zwanikken, René van Roij, Marjolein Dijkstra | Summary: The association of ions in electrolyte solutions at very low concentration and low temperature is studied using computer simulations and quasi-chemical ion-pairing theory. The specific case of the restricted primitive model […]

Free subgroups within the images of quantum representations

Kavli Affiliate: Toshitake Kohno | First 5 Authors: Louis Funar, Toshitake Kohno, , , | Summary: We prove that, except for a few explicit roots of unity, the quantum image of any Johnson subgroup of the mapping class group contains an explicit free non-abelian subgroup. | Search Query: ArXiv Query: search_query=au:”Toshitake Kohno”&id_list=&start=0&max_results=3 Read More

On G/N-Hilb of N-Hilb

Kavli Affiliate: Yukari Ito | First 5 Authors: Akira Ishii, Yukari Ito, Álvaro Nolla de Celis, , | Summary: In this paper we consider the iterated G-equivariant Hilbert scheme G/N-Hilb(N-Hilb) and prove that G/N-Hilb(N-Hilb(C^3)) is a crepant resolution of C^3/G isomorphic to the moduli space of theta-stable representations of the McKay quiver for certain stability […]

The Creation and Propagation of Radiation: Fields Inside and Outside of Sources

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 […]

Correlation functions quantify super-resolution images and estimate apparent clustering due to over-counting

Kavli Affiliate: Barbara Baird | First 5 Authors: Sarah Veatch, Benjamin Machta, Sarah Shelby, Ethan Chiang, David Holowka | Summary: We present an analytical method to quantify clustering in super-resolution localization images of static surfaces in two dimensions. The method also describes how over-counting of labeled molecules contributes to apparent self-clustering and how the effective […]
