Since the theoretical prediction 40 years ago of the resonating valence bond ground state and its potential role in the emergence of high temperature superconductivity, there has been a significant effort in materials discovery to produce real materials harboring quantum spin liquid (QSL) states in greater than one dimension. At the same time, the rise of topology has led to theoretical predictions of a variety of novel ground states arising from the kagome and pyrochlore lattices. The last decade has seen a significant expansion of the number of candidate quantum spin liquid materials built of kagome and pyrochlore lattices. These materials have excitations strongly suggestive of QSL ground states. In this talk, I will present an update on the current status of the field, from universality in behavior between different materials families to the results of attempts to induce metallicity and metal-insulator transitions in these usually highly insulating materials.
