Researchers have developed an optical technique to probe the internal dynamics and collective motion within Wigner crystals using light-induced excitons. This advancement allows scientists to observe previously elusive quantum states in atomically thin materials, providing a new tool for studying strongly correlated electronic systems without relying on traditional detection methods that might disrupt the fragile crystal structure.
Researchers Use Light to Study Electron Motion in Wigner Crystals

Insider Brief Press release – The group of BQC Prof. Tomasz Smoleński at the University of Basel, together with researchers from the Technical University of Munich, has found a new way to observe the collective motion of electrons in one of the most elusive states of matter: the Wigner crystal. Using light, the team was […]
Researchers at the University of Basel and Technical University of Munich have developed an optical method to study the collective motion of electrons in Wigner crystals. The team observed optical signatures produced by interactions between excitons and the ordered electrons in an atomically thin tungsten diselenide layer. The…
