An ultracold atom experiment using artificial spin–orbit coupling uncovers the finite-temperature phase diagram and a transition between a stripe-ordered and a magnetized phase.

Here we show that the finite-temperature phase diagram contains a region of phase separation between the superfluid and normal states that touches the boundary of second-order superfluid ...

This phase, however, currently occurs at very low temperatures—even so-called high-temperature superconductors, used in devices like MRI machines, must be kept nearly 100 °F below zero.

A team sees stripes in samples of twisted double bilayer graphene, indicating the presence of a nematic phase characterized by broken rotational symmetry.
