THE INERTIA OF LIGHT. VERIFICATION OF NEWTON’S SECOND LAW BY ACONFINED FLOW OF RADIATION IN A REFLECTIVE CAVITY

open access: yesAnales (Asociación Física Argentina), 2023
In 1904, the Austrian physicist Fritz Hasenöhrl examined by means of mental experiments the black body radiation in a reflecting cavity. By calculating the work required to keep the cavity moving at constant velocity in opposition to the radiation ...

Possible Simple Structures of the Universe to Include General Relativity Effects [PDF]

open access: yesINCAS Bulletin, 2017
The general relativity describes the universe properties, the gravity playing a fundamental role. One uses a metric tensor in a Riemann space, g  , which should be in agreement with a mass (or energy) tensor in order to satisfy the Einstein equation of

Monitoring Neutron Radiation in Extreme Gamma/X-Ray Radiation Fields

open access: yesSensors, 2020
The monitoring of neutron radiation in extreme high ≈1014 (#/cm2-s) neutron/photon fields and at extremely-low (≈10−3 #/cm2-s) levels poses daunting challenges—important in fields spanning nuclear energy, special nuclear material ...

Kerr-Nonlinearity-Triggered Nonclassicality of Magnons in a Photon-Magnon Coupling System

open access: yesPhotonics, 2022
Hybrid quantum systems have attracted much attention due to the fact that they combine the advantages of different physical subsystems. Cavity QED (cavity quantum electrodynamics) with magnons is a hybrid quantum systems that combines a YIG (Yttrium Iron
