Experiments in Frustrated Josephson Systems

This talk will explore in an experimentally accessible system how complex classical physics with frustration evolves into the quantum realm. We will explore this question in Josephson junction arrays using hybrid 2D semiconductor-superconductor hybrids, which allow gate-voltage control of Josephson coupling. Connections to the superconductor-insulator transition, anomalous metals, and topologically protected qubits will be considered. Note: this talk is about experiments.
