Lighting up ultrafast magnetism
When it comes to computers, we all know that faster is better. To date, the exponential growth in data processing and storage speeds has largely been driven by shrinking electronic circuits to ever smaller sizes. As we push up against the limits of semiconductor...
The humble light bulb proves a source of transverse spin
Almost a hundred years on from its first proposal, a number of questions remain around what spin is. While understood to be a basic property characterizing and distinguishing fundamental particles just as charge or mass do, it is still not clear what exactly spin...
Nobel laureate tells how to beat his own award-winning imaging technique
In the 1990s an optical imaging technique emerged that overturned the “diffraction limit”, which for over a century had defined the maximum achievable resolution an optical microscope could achieve at around half the wavelength of the illuminating light. At King’s...
