Curved Spacetime in a Quantum Simulator

[Translate to English:] Montage aus Astronomie-Foto von Gravitationslinseneffekt und Teilchen

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such as the behavior of individual electrons in an atom. But combining the two in a completely satisfactory way has yet to be achieved. The search for a “quantum theory of gravity” is considered one of the significant unsolved tasks of science.

This is partly because the mathematics in this field is highly complicated...

Never-before-seen State of Matter: Quantum Spin Liquids

Physicists said they have finally experimentally documented quantum spin liquids, a long sought-after exotic state of matter. The work marks a big step toward being able to produce this elusive state on demand and to gain a novel understanding of its mysterious nature.

In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers.

This bizarre state of matter is called a quantum spin liquid and, contrary to the name, has nothing to do with everyday liquids like water. Instead, it’s all about magnets that never freeze and the way electrons in them spin...
