Making non-magnetic photons feel a taste for magnetism

Light consists of chargeless particles called photons. While electrons, being charged, get deflected into curved paths when placed in a magnetic field, the chargeless photons do not feel a real magnetic field the same way. Devising an “artificial” or “fictitious” magnetic field for photons would... click to read more

Enabling a hydrogen-fueled future

Due to its nature as a clean fuel, there has been substantial interest in recent decades in developing hydrogen fuel cells and storage technologies. However, this "hydrogen economy" is currently limited by the fact that hydrogen is known to significantly reduce the toughness of steels.... click to read more
