Probing Vainsthein-screening gravity with galaxy clusters using internal kinematics and strong and weak lensing
Lorenzo Pizzuti, Ippocratis D. Saltas, Keiichi Umetsu +1
We use high-precision combined strong/weak lensing and kinematics measurements of the total mass profiles of the observed galaxy clusters MACS~J1206.2-0847 and Abell~S1063, to cons…
Localization Phenomena in Disordered Tantalum Films
Natalia Kovaleva, Dagmar Chvostova, A. Dejneka
Using dc transport and wide-band spectroscopic ellipsometry techniques we study localization phenomena in highly disordered metallic β-Ta films grown by rf sputtering deposition. T…
Localization effects in the disordered Ta interlayer of multilayer Ta-FeNi films: Evidence from dc transport and spectroscopic ellipsometry study
N. N. Kovaleva, D. Chvostova, O. Pacherova +4
Using dc transport and wide-band spectroscopic ellipsometry techniques, we study localization effects in the disordered metallic Ta interlayer of different thickness in the multila…
Failure of the mean-field description of magnetic fluctuations in the superconducting quantum dot
Václav Janiš, Jiawei Yan
The zero-temperature physics of interacting quantum dots attached to superconducting leads is now well understood. The overall qualitative picture is obtained from the static mean-…
O'TRAIN: a robust and flexible Real/Bogus classifier for the study of the optical transient sky
K. Makhlouf, D. Turpin, D. Corre +3
The scientific interest in studying high-energy transient phenomena in the Universe has largely grown for the last decade. Now, multiple ground-based survey projects have emerged t…
Quadratic curvature corrections to stringy effective actions and the absence of de Sitter vacua
Francesc Cunillera, William T. Emond, Antoine Lehébel +1
We investigate the combined effect of fluxes and higher-order curvature corrections, in the form of the Gauss-Bonnet term, on the existence of de Sitter vacua in a heterotic string…
