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 ...

Jet and hadron production in photon-photon collisions [PDF]

open access: yes, 1999
Di-jet and inclusive charged hadron production cross-sections measured in photon-photon collisions by OPAL are compared to NLO pQCD calculations. Jet shapes measured in photon-photon scattering by OPAL, in deep-inelastic ep scattering by H1 and in photon-

Coherent single-photon emission from colloidal lead halide perovskite quantum dots [PDF]

open access: yesScience, 2018
Perovskite quantum emitters The development of many optical quantum technologies is dependent on the availability of solid-state single quantum emitters with near-perfect optical coherence.

Searching for Anomalous Higgs Couplings in Peripheral Heavy Ion Collisions at the LHC [PDF]

open access: yes, 2000
We investigate the sensitivity of the heavy ion mode of the LHC to anomalous Higgs boson couplings to photons, H-photon-photon, through the analysis of the processes photon photon to b anti-b and photon photon to photon photon in peripheral heavy ion ...

Photon-counting CT: Technical Principles and Clinical Prospects.

open access: yesRadiology, 2018
Photon-counting CT is an emerging technology with the potential to dramatically change clinical CT. Photon-counting CT uses new energy-resolving x-ray detectors, with mechanisms that differ substantially from those of conventional energy-integrating ...

PHOTON-PHOTON INTERACTIONS [PDF]

open access: yesNuclear Physics A, 1981
Abstract A brief summary of the present status of photon-photon interactions is presented. Stress is placed on the use of two-photon collisions to test present ideas on the quark constituents of hadrons and on the theory of strong interactions.

On the Remarkable Features of the Lower Limits of Charge and the Radiated Energy of Antennas as Predicted by Classical Electrodynamics

open access: yesAtmosphere, 2016
Electromagnetic energy radiated by antennas working in both the frequency domain and time domain is studied as a function of the charge associated with the current in the antenna.

Shadows and photon spheres with spherical accretions in the four-dimensional Gauss–Bonnet black hole [PDF]

open access: yesThe European Physical Journal C, 2020
We investigate the shadows and photon spheres of the four-dimensional Gauss–Bonnet black hole with the static and infalling spherical accretions. We show that, for both cases, there always exist shadows and photon spheres.

Quantum nondemolition detection of a propagating microwave photon [PDF]

open access: yes, 2013
The ability to nondestructively detect the presence of a single, traveling photon has been a long-standing goal in optics, with applications in quantum information and measurement.
