Often novel physical phenomena arise when the dimensionality is reduced. For example, electrons in two-dimensions can exhibit a fractional charge. Using light as the main tool, we perform experiments to investigate the physics of low-dimensional materials with a goal towards control and manipulation of charge carriers and their internal degrees of freedom such as charge, spin and pseudo- spin.
