Using terahertz spacetime metrology, the study reveals that the Drude weight in mono- and bi-layer graphene exceeds non-interacting predictions due to many-body interactions coupled with the Dirac fermions' pseudospin wave function structure, demonstrating how single-particle electronic properties directly influence collective excitations in quantum materials.
This paper reports the experimental observation of Wigner crystallization in monolayer WSe at temperatures below 26 K and low carrier densities, achieved by optically detecting exciton diffraction from the resulting periodic potential, a process facilitated by the material's valley degree of freedom and strong longitudinal-transverse exciton splitting.
