### A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.

A series of advances seemed to promise the impossible: the existence of quantum states that would never, ever fall into disarray. But physicists are now discovering that the pull of disorder may not be so easily overcome.

### Maze Proof Establishes a ‘Backbone’ for Statistical Mechanics

Four mathematicians have estimated the chances that there’s a clear path through a random maze.

### Physicists Observe ‘Unobservable’ Quantum Phase Transition

Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.

### Is Perpetual Motion Possible at the Quantum Level?

A new phase of matter called a “time crystal” plays with our expectations of thermodynamics. The physicist Vedika Khemani talks with Steven Strogatz about its surprising quantum behavior.

### Room-Temperature Superconductor Discovery Meets With Resistance

A paper in *Nature* reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.

### For His Sporting Approach to Math, a Fields Medal

With Hugo Duminil-Copin, thinking rarely happens without moving. His insights into the flow-related properties of complex networks have earned him the Fields Medal.

### Quantum Simulators Create a Totally New Phase of Matter

One of the first goals of quantum computing has been to recreate bizarre quantum systems that can’t be studied in an ordinary computer. A dark-horse quantum simulator has now done just that.

### Eternal Change for No Energy: A Time Crystal Finally Made Real

Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.

### Mathematicians Prove Symmetry of Phase Transitions

A group of mathematicians has shown that at critical moments, a symmetry called rotational invariance is a universal property across many physical systems.
