An arrangement of spins known as a meron turns out to be easier to make in momentum space than in real space.

A new algorithm efficiently ranks competitors in settings ranging from sports tournaments to food-preference surveys.

A mechanism for accelerating charged particles in astrophysical plasmas has been reproduced with cold atoms in an optical trap.
