Electron Movement Spotted in Elusive Wigner Crystal Using Light

A strange crystal made of electrons just revealed its hidden motion

Physicists have found a new way to peer inside one of matter’s most elusive quantum states: the Wigner crystal, where electrons stop behaving like independent particles and organize into a crystal-like pattern. By shining light on an atomically thin material cooled close to absolute zero, researchers uncovered optical signals that reveal not just where the electrons are, but how they move together.

Electron movement spotted in elusive Wigner crystal using light

Researchers at the University of Basel, Switzerland and Technical University of Munich, have developed a new approach that reveals the motion of electrons in the Wigner crystal, one of the most elusive states of matter. The team was able to access properties of the crystal in its fragile quantum state using light.  First predicted nearly a century ago, the Wigner crystal is a solid phase of electrons that forms a organized crystal-like lattice s…

The optical glow of quantum crystals

Researchers have developed a new method to reveal the collective motion of electrons in one of the most elusive states of matter: the Wigner crystal. Using light, the physicists were able to uncover previously inaccessible properties of this fragile quantum state.

Quantum Crystals Reveal a Mysterious Optical Glow

In a breakthrough that could transform the study of strongly correlated quantum matter, researchers at the University of Basel and the Technical University of Munich have developed a way to observe how electrons move collectively inside a Wigner crystal. By using light to interrogate an atomically thin semiconductor, the team detected optical signatures that reveal not only the existence of this elusive state, but also aspects of its internal qu…
