condensed matter physics

Physicists have reached a long-sought goal. The catch is that their room-temperature superconductor requires crushing pressures to keep from falling apart.

Researchers have shown how to effectively transform one material into another using a finely shaped laser pulse.

Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.

Push or crush a new class of materials, and they’ll undergo record-breaking temperature changes.

At the molecular level, glass looks like a liquid. But an artificial neural network has picked up on hidden structure in its molecules that may explain why glass is rigid like a solid.

One hundred years after it was proposed, the Ising model is used to understand everything from magnets to brains.

Anyons don’t fit into either of the two known particle kingdoms. To find them, physicists had to erase the third dimension.

Sometimes a mirror that reflects 99.9999% of light isn’t good enough.

Glass is anything that’s rigid like a crystal, yet made of disordered molecules like a liquid. To understand why it exists, researchers are attempting to create the perfect, still-hypothetical “ideal glass.”
