Ground-state quantum geometry in superconductor–quantum dot chains
Ground-state quantum geometry in superconductor–quantum dot chains
Multiterminal Josephson junctions constitute engineered topological systems in arbitrary synthetic dimensions defined by the superconducting phases. Microwave spectroscopy enables the measurement of the quantum geometric tensor, a fundamental quantity describing both the quantum geometry and the topology of the emergent Andreev bound states in a unified manner. In this work …
