- 요약Collective phenomena can give quantum materials unusual properties not found in common materials. Electronic correlations are responsible for intriguing emergent effects like superconductivity, metal-to-insulator transitions, magnetism, etc. Also, anisotropic excitations of polar quantum matter can lead to hyperbolicity, when one crystal axis is metallic and another dielectric. Polaritons, half-light half-matter quasiparticles, have exotic properties in hyperbolic media and are influenced by electronic correlations. In this dissertation, we use infrared near-field optical nanoscopy to interrogate various quantum materials both with strong anisotropy and electronic correlations and study their interplay and tunability. We first understand how near-field microscopes read out optical anisotropy (i) and use our theory to study the metal-to-insulator transition in polycrystalline VO2 (ii). Next, we demonstrate extreme tunability of hyperbolic phonon polaritons in α-MoO3 by interfacing graphene (iii). Finally, we introduce two novel hyperbolic systems: CrSBr and MoOCl2, which host magnetically-enhanced hyperbolic exciton polaritons (iv) and ultra-low-loss hyperbolic plasmon polaritons (v), respectively.
