Quasiparticles called rotons have been seen for the first time in a Bose–Einstein condensate (BEC) of ultracold atoms. The research was done by physicists in Austria, Germany and Italy and could lead ...

For decades, researchers have explored how electrons behave in quantum materials. Under certain conditions, electrons interact strongly with each other instead of moving independently, leading to ...

SEOUL, South Korea, March 27, 2025 /PRNewswire/ --Yonsei University researchers have provided new experimental evidence for electronic rotons and their connection to Wigner crystallization in a ...

Discovered in liquid helium about 80 years ago, superfluidity is a counterintuitive phenomenon, in which quantum physics and particle-wave duality manifest at the macroscopic level. Since then, it has ...

Researchers have uncovered tiny flakes of Wigner crystals—unique structures formed entirely by electrons—by identifying unusual, aperiodic electronic signals. This breakthrough method reveals hidden ...
