The BKT Transition: Vortices, Topology and a No...
In two dimensions, ordinary order is impossible, yet thin superfluid films still have a sharp transition. The answer is vortices that pair up and then unbind. Here is the BKT...

What Is the Meissner Effect, and Why Do Superco...
Cool certain materials far enough and two things happen at once: electrical resistance vanishes, and magnetic field is pushed out of the interior. That expulsion, found by Meissner and Ochsenfeld...

The Ising model is the simplest picture of a magnet: a grid of arrows that can only point up or down, each wanting to match its neighbours. Heat scrambles them;...

What Is a Superfluid, and Why Does Helium Climb...
Cool liquid helium below 2.17 kelvin and it turns into a superfluid: it pours through gaps too fine for ordinary liquids, creeps up the walls of its container and can...

Bose and Einstein: What Is a Bose–Einstein Cond...
A Bose–Einstein condensate is a dilute gas of bosons cooled until a macroscopic number share the same quantum ground state. Bose’s 1924 photon statistics and Einstein’s extension set the idea;...

What Happens at Absolute Zero? Why −273.15 °C C...
Absolute zero is the bottom of the temperature scale, but physics says you can never quite get there. On the way down, matter turns superfluid, expels magnetic fields and piles...
