Ultrafast magnetism: Heating magnets, freezing time

Magnetic solids can be demagnetized quickly with a short laser pulse, and there are already so-called HAMR (Heat Assisted Magnetic Recording) memories on the market that function according to this principle. However, the ...

Particle accelerators may get a boost from oxygen

Whipping up world-class particle accelerator structures has long been a process akin to following a favorite recipe. Many of the best-performing samples are prepared using processes developed through trial and error over ...

The boiling crisis and how to avoid it

It's rare for a pre-teen to become enamored with thermodynamics, but those consumed by such a passion may consider themselves lucky to end up at a place like MIT. Madhumitha Ravichandran certainly does. A Ph.D. student in ...

Ultracold transistors serve as their own memory devices

Digital transistors—assembled by the billions in today's computer chips—act as near-perfect electronic switches. In the "on" position, achieved when an above-threshold voltage is applied to the device, the transistor ...
