Green's function approach to Chern-Simons extended electrodynamics: An effective theory describing topological insulators

Martín-Ruiz, A.; Cambiaso, M.; Urrutia, L.F. (American Physical Society, 2015-12)

Boundary effects produced by a Chern-Simons (CS) extension to electrodynamics are analyzed exploiting the Green's function (GF) method. We consider the electromagnetic field coupled to a. term in a way that has been proposed ...

Computability of the Radon-Nikodym derivative

Hoyrup, Mathieu; Rojas, Cristóbal; Weihrauch, Klaus (Pre-print, 2011)

We study the computational content of the Radon-Nokodym theorem from measure theory in the framework of the representation approach to computable analysis. We define computable measurable spaces and canonical representations ...

Proper caterpillars are distinguished by their symmetric chromatic function

Aliste Prieto, José; Zamora, José (Pre-print, 2012)

Abstract. This paper deals with the so-called Stanley conjecture, which asks whether they are non-isomorphic trees with the same symmetric function generalization of the chromatic polynomial. By establishing a correspondence ...

The Gaia-ESO Survey: revisiting the Li-rich giant problem

Casey, A. R.; Ruchti, G.; Masseron, T.; Randich, S.; Gilmore, G.; Lind, K.; Kennedy, G. M.; Koposov, S. E.; Hourihane, A.; Franciosini, E.; Lewis, J. R.; Magrini, L.; Morbidelli, L.; Sacco, G. G.; Worley, C. C.; Feltzing, S.; Jeffries, R. D.; Vallenari, A.; Bensby, T.; Bragaglia, A.; Flaccomio, E.; Francois, P.; Korn, A. J.; Lanzafame, A.; Pancino, E.; Recio-Blanco, A.; Smiljanic, R.; Carraro, G.; Costado, M. T.; Damiani, F.; Donati, P.; Frasca, A.; Jofre, P.; Lardo, C.; de Laverny, P.; Monaco, L.; Prisinzano, L.; Sbordone, L.; Sousa, S. G.; Tautvaisien, G.; Zaggia, S.; Zwitter, T.; Delgado Mena, E.; Chorniy, Y.; Martell, S. L.; Silva Aguirre, V.; Miglio, A.; Chiappini, C.; Montalban, J.; Morel, T.; Valentini, M. (OXFORD UNIV PRESS, 2016-07)

The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during the Gaia-ESO Survey, which includes the ...

Pan-STARRS and PESSTO search for an optical counterpart to the LIGO gravitational-wave source GW150914

Smartt, SJ; Chambers, KC; Smith, KW; Huber, ME; Young, DR; Cappellaro, E; Wright, DE; Coughlin, M; Schultz, ASB; Denneau, L; Flewelling, H; Heinze, A; Magnier, EA; Primak, N; Rest, A; Sherstyuk, A; Stalder, B; Stubbs, CW; Tonry, J; Waters, C; Willman, M; Anderson, JP; Baltay, C; Botticella, MT; Campbell, H; Dennefeld, M; Chen, TW; Della Valle, M; Elias-Rosa, N; Fraser, M; Inserra, C; Kankare, E; Kotak, R; Kupfer, T; Harmanen, J; Galbany, L; Gal-Yam, A; Le Guillou, L; Lyman, JD; Maguire, K; Mitra, A; Nicholl, M; Olivares, F; Rabinowitz, D; Razza, A; Sollerman, J; Smith, M; Terreran, G; Valenti, S; Gibson, B; Goggia, T (OXFORD UNIV PRESS, 2016-11)

We searched for an optical counterpart to the first gravitational-wave source discovered by LIGO (GW150914), using a combination of the Pan-STARRS1 wide-field telescope and the Public ESO Spectroscopic Survey of Transient ...

New spectroscopic binary companions of giant stars and updated metallicity distribution for binary systems

Bluhm, P; Jones, MI; Vanzi, L; Soto, MG; Voss, J; Wittenmyer, RA; Drass, H; Jenkins, JS; Olivares, F; Mennickent, RE; Vuckovic, M; Rojo, P; Melo, CHF (EDP SCIENCES, 2016-09)

We report the discovery of 24 spectroscopic binary companions to giant stars. We fully constrain the orbital solution for 6 of these systems. We cannot unambiguously derive the orbital elements for the remaining stars ...

Síntesis y caracterización de un complejo de Re' y 3-cloro-6-N-Pirazolpiridazina

Guzmán Olivares, Nicolás Joaquín (Universidad Andrés Bello, 2017)

En esta unidad de investigación se describe detalladamente la síntesis y la caracterización de un nuevo compuesto de renio (I) tricarbonilo con un ligando bidentado diimina 3-cloro-6-N-pirazolpiridazina (Hemi-N), este ...

THE ARAUCARIA PROJECT: A STUDY OF THE CLASSICAL CEPHEID IN THE ECLIPSING BINARY SYSTEM OGLE LMC562.05.9009 IN THE LARGE MAGELLANIC CLOUD

Gieren, W.; Pilecki, B.; Pietrzyński, G.; Graczyk, D.; Udalski, A.; Soszyński, I.; Thompson, I.B.; Moroni, P.G.P.; Smolec, R.; Konorski, P.; Górski, M.; Karczmarek, P.; Suchomska, K.; Taormina, M.; Gallenne, A.; Storm, J.; Bono, G.; Catelan, M.; Szymański, M.; Kozłowski, S.; Pietrukowicz, P.; Wyrzykowski, Ł.; Poleski, R.; Skowron, J.; Minniti, D.; Ulaczyk, K.; Mróz, P.; Pawlak, M.; Nardetto, N. (IOP PUBLISHING, 2015-12)

We present a detailed study of the classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009. The Cepheid is a fundamental mode pulsator with a period of 2.988 days. The orbital ...

Observations on interfacing loop quantum gravity with cosmology

Pawlowski, T (American Physical Society, 2015-12)

A simple idea of relating the loop quantum gravity (LQG) and loop quantum cosmology (LQC) degrees of freedom is introduced and used to define a relatively robust interface between these theories in context of toroidal ...

Chemical abundances of giant stars in NGC 5053 and NGC 5634, two globular clusters associated with the Sagittarius dwarf spheroidal galaxy?

Sbordone, L.; Monaco, L.; Moni Bidin, C.; Bonifacio, P.; Villanova, S.; Bellazzini, M.; Ibata, R.; Chiba, M.; Geisler, D.; Caffau, E.; Duffau, S. (EDP SCIENCES, 2015-07)

Context. The tidal disruption of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) is producing the most prominent substructure in the Milky Way (MW) halo, the Sagittarius Stream. Aside from field stars, it is suspected ...
