New optical method reveals internal dynamics of elusive Wigner crystals
Researchers at the University of Basel and the Technical University of Munich 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.
Researchers at the University of Basel and the Technical University of Munich have developed a novel method to observe the internal dynamics of Wigner crystals, a highly elusive state of matter. By using light to illuminate a single atomic layer of tungsten diselenide cooled to near absolute zero, the team was able to reveal previously inaccessible properties of the Wigner crystal.
The new technique, reported in Nature Physics, allows scientists to probe the collective behavior of electrons within the crystal and uncover how these particles interact and respond to external perturbations. The study's findings, complemented by theoretical work from the Technical University of Munich, open up new avenues for exploring the fundamental physics of strongly correlated systems, where the properties of materials arise from the collective behavior of many interacting particles.
