Electric-Field Induced Majorana Fermions in Armchair Carbon Nanotubes
Jelena Klinovaja, Suhas Gangadharaiah, Daniel Loss
We consider theoretically an armchair Carbon nanotube (CNT) in the presence of an electric field and in contact with an s-wave superconductor. We show that the proximity effect ope…
Strange matter in core-collapse supernovae
I. Sagert, T. Fischer, M. Hempel +4
We discuss the possible impact of strange quark matter on the evolution of core-collapse supernovae with emphasis on low critical densities for the quark-hadron phase transition. F…
Non-standard s process in low metallicity massive rotating stars
U. Frischknecht, R. Hirschi, F. -K. Thielemann
Context. Rotation is known to affect the nucleosynthesis of light elements in massive stars, mainly by rotation-induced mixing. In particular, rotation boosts the primary nitrogen…
Impact of supernova dynamics on the νp-process
A. Arcones, C. Fröhlich, G. Martínez-Pinedo
We study the impact of the late time dynamical evolution of ejecta from core-collapse supernovae on νp-process nucleosynthesis. Our results are based on hydrodynamical simulations…
Signature of the long range triplet proximity effect in the density of states
Milos Knezevic, Luka Trifunovic, Zoran Radovic
We study the impact of the long-range spin-triplet proximity effect on the density of states (DOS) in planar SF1F2S Josephson junctions that consist of conventional superconductors…
Neutrino spectra evolution during proto-neutron star deleptonization
T. Fischer, G. Martínez-Pinedo, M. Hempel +1
The neutrino-driven wind, which occurs after the onset of a core-collapse supernova explosion, has long been considered as the possible site for the synthesis of heavy r-process el…
Existence and uniqueness of measure solutions for a system of continuity equations with non-local flow
Gianluca Crippa, Magali Lécureux-Mercier
In this paper, we prove existence and uniqueness of measure solutions for the Cauchy problem associated to the (vectorial) continuity equation with a non-local flow. We also give a…
Representations With a Reduced Null Cone
Hanspeter Kraft, Gerald W. Schwarz
Let G be a complex reductive group and V a G-module. Let π: V \to V//G be the quotient morphism and set N(V) = π^{-1}(π(0)). We consider the following question. Is the null cone N(…
On the Requirements for Realistic Modeling of Neutrino Transport in Simulations of Core-Collapse Supernovae
Eric J. Lentz, Anthony Mezzacappa, O. E. Bronson Messer +3
We have conducted a series of numerical experiments with the spherically symmetric, general relativistic, neutrino radiation hydrodynamics code Agile-BOLTZTRAN to examine the effec…
Singlet-triplet splitting in double quantum dots due to spin orbit and hyperfine interactions
Dimitrije Stepanenko, Mark Rudner, Bertrand I. Halperin +1
We analyze the low-energy spectrum of a two-electron double quantum dot under a potential bias in the presence of an external magnetic field. We focus on the regime of spin blockad…
Incoherent dynamics in the toric code subject to disorder
Beat Röthlisberger, James R. Wootton, Robert M. Heath +2
We numerically study the effects of two forms of quenched disorder on the anyons of the toric code. Firstly, a new class of codes based on random lattices of stabilizer operators i…
Gas and stellar metallicities in HII galaxies
Pieter Westera, François Cuisinier, Didier Curty +1
We examine the gas and stellar metallicities in a sample of HII galaxies from the Sloan Digital Sky Survey, which possibly contains the largest homogeneous sample of HII galaxy spe…
Allan Sandage and the Cosmic Expansion
G. A. Tammann, B. Reindl
This is an account of Allan Sandage's work on (1) The character of the expansion field. For many years he has been the strongest defender of an expanding Universe. He later explain…
Improving smoothed particle hydrodynamics with an integral approach to calculating gradients
Domingo Garcia-Senz, Ruben M. Cabezon, Jose Antonio Escartin
In this paper we develop and test a fully conservative SPH scheme based on a tensor formulation that can be applied to simulate astrophysical systems. In the proposed scheme, deriv…
Anomaly in the K^0_S Sigma^+ photoproduction cross section off the proton at the K* threshold
R. Ewald, A. V. Anisovich, B. Bantes +57
The photoproduction reaction is investigated in the energy region from threshold to \,MeV. The differential cross section exhibits increasin…
Nuclear correlations and the r-process
A. Arcones, G. F. Bertsch
We show that long-range correlations for nuclear masses have a significant effect on the synthesis of heavy elements by the r-process. As calculated by Delaroche et al. [1], these…
The supernova Ia 2011fe in M101, its tip of the red-giant branch (TRGB) distance, and the value of H_0
G. A. Tammann, B. Reindl
The light curve parameters of the normal type Ia SN2011fe are derived from the rich archive of the AAVSO. This leads, together with the TRGB distance modulus of (m-M) = 29.39 +/- 0…
Thin-Film Magnetization Dynamics on the Surface of a Topological Insulator
Yaroslav Tserkovnyak, Daniel Loss
We theoretically study the magnetization dynamics of a thin ferromagnetic film exchange-coupled with a surface of a strong three-dimensional topological insulator. We focus on the…
