Light helps us wake up, keeps us alert, and guides our sleep. But what happens when light becomes erratic? As a researcher ...

In order to suppress backgrounds, mostly from processes involving top-quark pair production, both leptons are required to be of the same electrical charge. The experimental signature is thus a ...

For example, using licensing and production data, LOs can identify real estate agents whose go-to loan officers have left the business. That’s thousands of potential relationships waiting to be ...

The star and the director of “Sinners” have risen in parallel since first working together over a decade ago. In a joint interview, they explain their connection. Ryan Coogler, top, with ...

Two popular Sportsnet analysts are not impressed with Maple Leafs captain Auston Matthews and have publicly called him out over his lackluster play. The good news for the Toronto Maple Leafs is that ...

In particular, radiative corrections (described by one- and multi-loop Feynman diagrams) have to be considered. Although a growing number of physicists are involved in such projects, multi-loop ...

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 ...
