Quantum Materials (QuMa) are expected to advance our understanding of several phenomena emerging from complex interactions. The class of QuMa represented by two-dimensional (2D) systems, including graphene and other van der Waals (hetero)structures, gained prominence in the last decade due to its facility to allow property tuning. An important challenge to nanoscience and nanotechnology in general is how to access the fundamental materials properties without disturbing the material with the probes. To address this challenge, this work reports on our efforts to advance the study of near-field regime of electrons, phonons and photons in graphene and other 2D systems using Raman spectroscopy, by pushing the limits of space and time resolution. Space is addressed with nano-optics, more specifically with tip-enhanced Raman spectroscopy (TERS). Time is addressed by exploring a phenomenon we call Stokes-anti-Stokes correlated Raman scattering, which generates a pair of photons that can carry quantum characteristics like entanglement.
