All-optical three-dimensional electron pulse compression [PDF]

, 2014
We propose an all-optical, three-dimensional electron pulse compression scheme in which Hermite–Gaussian optical modes are used to fashion a three-dimensional optical trap in the electron pulse's rest frame.

Complexity and Entropy in Legal Language

Frontiers in Physics, 2021
We study the language of legal codes from different countries and legal traditions, using concepts from physics, algorithmic complexity theory and information theory. We show that vocabulary entropy, which measures the diversity of the author’s choice of

Semi-empirical analysis of leptons in gases in crossed electric and magnetic fields. Part II. Transverse compression of muon beams [PDF]

, 2023
This article employs fluid equations to analyze muon beams in gases subject to crossed electric and magnetic fields, focusing, in particular, on a scheme proposed by Taqqu [Phys. Rev. Lett.

Physics of compressed baryonic matter [PDF]

Journal of Physics: Conference Series, 2013
The experimental investigation of the QCD phase diagram with heavy ion collisions is an ongoing intense research topic at international accelerator facilities since the 80's and recently got new boost with the first results from the LHC experiments. Together with results from the top RHIC energies they investigate partonic matter in every detail at ...

A numerical investigation into the plastic buckling paradox for circular cylindrical shells under axial compression [PDF]

, 2014
It is widely accepted that for many buckling problems of plates and shells in the plastic range the flow theory of plasticity leads to a significant overestimation of the buckling stress while the deformation theory provides much more accurate ...

The physical dimensions of the compressed breast

The British Journal of Radiology, 1991
The success of the National Breast Screening Program relies on accurate dose measurements, essential for any risk–benefit analysis and radiation protection considerations (Forrest, 1986). This need to measure absorbed doses within and around the irradiated breast necessitates the use of carefully selected materials from which phantoms and radiation ...

A physics-informed neural network framework for consolidation parameter prediction using controlled clay-sand mixtures

Results in Engineering
This paper introduces a novel Physics-Informed Neural Network (PINN) model for predicting the coefficient of consolidation (Cv) in high plasticity clays. The model was trained from experimental data obtained from controlled clay-sand mixtures.

Coulomb interaction-induced jitter amplification in RF-compressed high-brightness electron source ultrafast electron diffraction

New Journal of Physics, 2017
We have theoretically and experimentally demonstrated an RF compression-based jitter-amplification effect in high-brightness electron source ultrafast electron diffraction (UED), which degrades the temporal resolution significantly.

Generation, amplification, and nonlinear self-compression of powerful superradiance pulses

, 2012
Superradiance (SR) of electron bunches can be considered an effective method of production of ultrashort electromagnetic pulses. Different types of SR associated with different mechanisms (cyclotron, Cherenkov, and bremsstrahlung) of stimulated emission ...
