The Mixmaster Universe in a generalized uncertainty principle framework
Abstract The Bianchi IX cosmological model is analyzed in a generalized uncertainty principle framework. The Arnowitt–Deser–Misner reduction of the dynamics is performed and a time-coordinate, namely the volume of the Universe, naturally arises....

Quasifission and difference in formation of evaporation residues in the 16O+184W and 19F+181Ta reactions
Abstract The role of the entrance channel has been studied to ascertain a cause of the observed difference between the evaporation residue cross sections normalized to the fusion cross sections in the 19F+ 181Ta and 16O+ ...

Cosmological expansion governed by a scalar field from a 5D vacuum
Abstract We consider a single field governed expansion of the universe from a five dimensional (5D) vacuum state. Under an appropiate change of variables the universe can be viewed in a effective manner as expanding in 4D with an effective equation...

Self-gravitational corrections to the Cardy–Verlinde formula of the Achúcarro–Ortiz black hole
Abstract Recently, it was shown that the entropy of the black hole horizon in the Achúcarro–Ortiz spacetime can be described by the Cardy–Verlinde formula. In this Letter, we compute the self-gravitational corrections to the Cardy–Verlinde formula...

Implications of leptonic unitarity violation at neutrino telescopes
Abstract A measurement of the ultrahigh-energy (UHE) cosmic neutrinos at a km3-size neutrino telescope will open a new window to constrain the 3 × 3 ...

Left–right asymmetric holographic RG flow with gravitational Chern–Simons term
Abstract We consider the holographic renormalization group (RG) flow in three-dimensional gravity with the gravitational Chern–Simons term coupled to some scalar fields. We apply the canonical approach to this higher derivative case and employ the...

High-precision covariant one-boson-exchange potentials for np scattering below 350 MeV
Abstract All realistic potential models for the two-nucleon interaction are to some extent based on boson exchange. However, in order to achieve an essentially perfect fit to the scattering data, characterized by a ...

Effects of magnetic field on the low temperature emission of nitrogen vacancy centres in diamond
Abstract Under optical illumination in the blue or green, negatively charged nitrogen vacancy centres in diamond emit in the red. The intensity of this emission varies slightly depending on spin state occupation. Optical transitions occur...

NonMarkov Ito Processes with 1- state memory
Abstract A Markov process, by definition, cannot depend on any previous state other than the last observed state. An Ito process implies the Fokker-Planck and Kolmogorov backward time partial differential eqns. for transition densities, which in...

Experimental investigation of 3D shock waves on nonlinear acoustical vortices
Abstract We report experimental results about the 3D structure of shock waves on nonlinear acoustical vortices (AV). We will investigate classical shock waves (in the direction of propagation) and the azimuthal ones (in the transverse plane). At...

Significance of tension for gravitating masses in Kaluza–Klein models
Abstract In this Letter, we consider the six-dimensional Kaluza–Klein models with spherical compactification of the internal space. Here, we investigate the case of bare gravitating compact objects with the dustlike equation of state ...

The photon angular momentum controversy: Resolution of a conflict between laser optics and particle physics
Abstract The claim some years ago, contrary to all textbooks, that the angular momentum of a photon (and gluon) can be split in a gauge-invariant way into an orbital and spin term, sparked a major controversy in the Particle Physics community,...

Mass Attenuation Coefficient and Effective Atomic Number of Ag/Cu/Zn Alloy at Different Photon Energy by Compton Scattering Technique
Abstract Mass attenuation coefficients and effective atomic numbers of Ag/Cu/Zn alloy (14.80%/57.61%/27.59% weight fraction) were determined at energy range 220 to 662 keV using gamma rays transmission method. The photon energy has been changed by...

On the interior of (quantum) black holes
Abstract Different approaches to quantum gravity conclude that black holes may possess an inner horizon, in addition to the (quantum corrected) outer ‘Schwarzschild’ horizon. In this Letter we assume the existence of this inner horizon and explain...
