Electronic structure, magnetic and transport properties of antiferromagnetic Weyl semimetal GdAlSi
Antu Laha, Asish K. Kundu, Niraj Aryal +12
We report the topological electronic structure, magnetic, and magnetotransport properties of a noncentrosymmetric compound GdAlSi. Magnetic susceptibility shows an antiferromagneti…
Nano-Imaging of Landau-Phonon Polaritons in Dirac Heterostructures
Lukas Wehmeier, Suheng Xu, Rafael A. Mayer +19
Polaritons are light-matter quasiparticles that govern the optical response of quantum materials and enable their nanophotonic applications. We have studied a new type of polariton…
Harnessing excitons at the nanoscale -- photoelectrical platform for quantitative sensing and imaging
Zhurun Ji, Mark E. Barber, Ziyan Zhu +8
Excitons -- quasiparticles formed by the binding of an electron and a hole through electrostatic attraction -- hold promise in the fields of quantum light confinement and optoelect…
Electronic interactions in Dirac fluids visualized by nano-terahertz spacetime interference of electron-photon quasiparticles
Suheng Xu, Yutao Li, Rocco A. Vitalone +15
Ultraclean graphene at charge neutrality hosts a quantum critical Dirac fluid of interacting electrons and holes. Interactions profoundly affect the charge dynamics of graphene, wh…
Visualizing moiré ferroelectricity via plasmons and nano-photocurrent in graphene/twisted-WSe2 structures
Shuai Zhang, Yang Liu, Zhiyuan Sun +28
Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain classes of van der Waals (vdW) material heterostructures. The discovery of ferroelectricit…
