Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation

open access: yesNew Journal of Physics, 2013
Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

Charge noise and spin noise in a semiconductor quantum device [PDF]

open access: yes, 2014
Self-assembled quantum dots are very attractive as the building blocks for quantum light sources and spin qubits. For instance, a single quantum dot is a robust, fast, narrow-linewidth source of single photons, features not shared by any other ...

Photon differentials [PDF]

open access: yesProceedings of the 5th international conference on Computer graphics and interactive techniques in Australia and Southeast Asia, 2007
A number of popular global illumination algorithms uses density estimation to approximate indirect illumination. The density estimate is performed on finite points -- particles -- generated by a stochastic sampling of the scene. In the course of the sampling, particles, representing light, are stochastically emitted from the light sources and reflected

The conversion coefficients from Нр(10) to effective dose in the fields of photon radiation and their use in the development of occupational exposure models

open access: yesРадиационная гигиена, 2023
The paper presents the values of the conversion coefficients from the operational quantity, HP(10)/ to the protection quantity, effective dose (E). The conversion coefficients were calculated in a number of points located at a depth of 10 mm under the ...

Observation of the muon inner bremsstrahlung at LEP1 [PDF]

open access: yes, 2007
Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0 ...

Evaluation of the Electron Contamination in Photon Therapy Using BEAMnrc Code

open access: yesمجله دانشکده پزشکی اصفهان, 2019
Background: Today, high-energy photon beams are widely used in the treatment of all types of cancers. However, the production of electrons as contaminants in the photon pathway provides the necessity for research in this field.

Theory for the Beam Splitter in Quantum Optics: Quantum Entanglement of Photons and Their Statistics, HOM Effect

open access: yesMathematics, 2022
The theory of the beam splitter (BS) in quantum optics is well developed and based on fairly simple mathematical and physical foundations. This theory has been developed for any type of BS and is based on the constancy of the reflection coefficients R ...
