Scientists have developed a dual-laser Brillouin optical correlation-domain reflectometry (BOCDR) system that uses two ...

By studying polarisation, or the alignment of light waves, scientists have now determined that Compton scattering is likely responsible for producing X-rays in these extreme environments.

The topics covered are Feynman diagram rules, microscopic mean-field theories (Hartree-Fock and Kohn-Sham theories, natural orbitals), many-body perturbation theory, large-scale diagonalization ...

Feynman path integrals are ubiquitous in quantum physics, even if a large part of the scientific community still considers them as a heuristic tool that lacks a sound mathematical definition. Our book ...
