Yesterday I worked from scratch at a problem which certainly others have already solved in the past. I have mixed feelings with such situations: on one side I hate to reinvent the wheel, especially…

In metals like copper and aluminium, conduction electrons move around freely, in the same way as particles in a gas or a liquid. But when impurities are introduced into the metal's crystal…

I submitted an article with simple calculations where the "short-distance physics" is integrated out automatically rather than "manually". http://arxiv.org/abs/1409.8326 Happy reading! Abstract: I…

A week ago I offered readers of this blog to review a paper I had just written, as its publication process did not include any form of screening (as opposed to what is customary for articles in…

I have been given the privilege of publishing during the Beta test period in the Open Access journal The Winnower for no cost but my time and care.  I was also given assistance by the…

Bringing the concept of peer review to another dimension, I am offering you to read a review article I just wrote. You are invited to contribute to its review by suggesting improvements, corrections…

The LHCb experiment collaborators at the Large Hadron Collider have announced discovery of two new particles in the baryon family. The particles, known as the Xi_b'- and Xi_b*-, were predicted…

A whirlpool of hybrid light-matter particles called polaritons has been created using a spiral laser beam. Polaritons are hybrid particles that have properties of both matter and light. The ability…

When two giant LIGO detectors are switched on in the US next year, they will help scientists pick up the faint ripples of black hole collisions millions of years ago, known as gravitational waves.…

I am quite happy to report today that the CMS experiment at the CERN Large Hadron Collider has just published a new search which fills a gap in studies of extended Higgs boson sectors. It is a search…
