Low-Energy Quasiparticles Probed by Heat Transport in the Iron Based Superconductor LaFePO
Michael Sutherland, J. Dunn, William Toews +4
We have measured the thermal conductivity of the iron pnictide superconductor LaFePO down to temperatures as low as T=60mK and in magnetic fields up to 5 T. The data shows a large…
Measurement of the Radiation Energy in the Radio Signal of Extensive Air Showers as a Universal Estimator of Cosmic-Ray Energy
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +447
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Au…
Strong in-plane anisotropy in the electronic structure of fixed-valence -LuAlB
Pascal Reiss, Jordan Baglo, Hong'En Tan +6
The origin of intrinsic quantum criticality in the heavy-fermion superconductor -YbAlB has been attributed to strong Yb valence fluctuations and its peculiar crystal struct…
Evidence of superconductivity on the border of quasi-2D ferromagnetism in Ca2RuO4 at high pressure
Patricia L. Alireza, Fumihiko Nakamura, Swee K. Goh +6
The layered perovskite Ca2RuO4 is a spin-one Mott insulator at ambient pressure and exhibits metallic ferromagnetism at least up to ~ 80 kbar with a maximum Curie temperature of 28…
Measurement of the cosmic ray spectrum above eV using inclined events detected with the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +461
A measurement of the cosmic-ray spectrum for energies exceeding eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\…
Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +448
The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared…
Magnetic Deflections of Ultra-High Energy Cosmic Rays from Centaurus A
Azadeh Keivani, Glennys R. Farrar, Michael Sutherland
We present the results of a study that simulates trajectories of ultra-high energy cosmic rays from Centaurus A to Earth, for particle rigidities from EV to 100 EV, i.e.,…
Chemical Pressure and Physical Pressure in BaFe_2(As_{1-x}P_{x})_2
Lina E. Klintberg, Swee K. Goh, Shigeru Kasahara +6
Measurements of the superconducting transition temperature, T_c, under hydrostatic pressure via bulk AC susceptibility were carried out on several concentrations of phosphorous sub…
The Pierre Auger Observatory: Contributions to the 33rd International Cosmic Ray Conference (ICRC 2013)
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +495
Contributions of the Pierre Auger Collaboration to the 33rd International Cosmic Ray Conference, Rio de Janeiro, Brazil, July 2013
The Galactic Magnetic Field and UHECR Optics
Glennys R. Farrar, Nafiun Awal, Deepak Khurana +1
A good model of the Galactic magnetic field is crucial for estimating the Galactic contribution in dark matter and CMB-cosmology studies, determining the sources of UHECRs, and als…
An improved limit to the diffuse flux of ultra-high energy neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration, Alexander Aab, Pedro Abreu +462
Neutrinos in the cosmic ray flux with energies near 1 EeV and above are detectable with the Surface Detector array of the Pierre Auger Observatory. We report here on searches throu…
