Quantum Materials is a concept that has broadened significantly in recent years, spanning beyond strongly correlated electron materials. In two-dimensional (2D) systems, several classes of quantum materials have been identified beyond graphene, such as transition metal dichalcogenides, van der Waals crystals, and topological insulators. 2D materials are being widely investigated for their appealing properties such as high flexibility, optical transparency or enormous carrier mobility, superior catalytic properties and robust ferromagnetism when sliced to the monolayer limit. Because the electrons in these materials are exposed to interlayer coupling, the properties of these materials are defined not only by the constituent monolayers, but also by the interactions between the layers. Many fascinating electrical, optical and magnetic properties have recently been reported in quantum materials owing to their reduced dimensionality (strong quantum confinement), and enhanced Coulomb interactions. These materials offer the great opportunity to tune their electronic and magnetic states, structure, and interlayer coupling through external stimuli such as photons, electric and magnetic fields and pressure. To broaden the current knowledge on quantum materials, it is necessary to develop operando techniques to quantify, manipulate and measure their properties over a wide range of temporal and spatial scales and under external perturbations.This symposium will focus on investigations into the physical properties (magnetic, optical, and electronic) of 2D quantum materials upon application of external perturbations, using a wide range of experimental and computational tools. The principal goal of this symposium is to bring together both experimentalists and theoreticians investigating the physics, chemistry, materials science and engineering aspects of quantum materials. With a mix of young scientists and established leaders in the field as invited speakers, the symposium will capture the new and most impactful developments in the field, and simultaneously enable researchers to receive a deeper perception of this emerging field and its grand challenges and opportunities. The development of understanding, knowledge, new methodologies and tools will accelerate the discovery of new quantum materials and advance the ability to probe, predict, and exploit their remarkable properties.
