Observation of a Two-Dimensional Anisotropic Luttinger Liquid in a Moiré Material
Explore groundbreaking research in quantum physics through this 45-minute lecture that delves into the observation of two-dimensional anisotropic Luttinger liquid behavior in moiré materials. Learn about the limitations of traditional Fermi-liquid theory and discover how two-dimensional materials and moiré systems open new avenues for investigating non-Fermi liquid behaviors in strongly correlated electronic systems. Examine the fascinating discovery of moiré Luttinger liquids in small-angle twisted tungsten ditelluride (WTe2), challenging conventional understanding of Luttinger liquid physics typically associated with one-dimensional systems. Gain insights into innovative approaches in material and device design, measurement techniques, and the application of extreme conditions to advance understanding of strongly correlated quantum phenomena in 2D materials. The lecture is delivered by Dr. Pengjie Wang, an assistant professor in physics at the University of Illinois Urbana-Champaign, whose expertise spans strong correlations and topology in 2D crystals, twisted stacks, and ultra-low temperature technique developments.
