We develop mesoscopic quantum devices to reveal, manipulate, and understand emergent quantum degrees of freedom in correlated materials.
Symmetry breaking and nonreciprocal superconducting transport in RbV3Sb5, CsV3Sb5, and Td-MoTe2, including magnetic hysteresis, half-quantum flux states, and superconducting diode effects.
Thin-flake RbV3Sb5 and CsV3Sb5 devices reveal how kagome geometry, topology, and electronic correlations generate nematicity, unconventional pairing, and switchable quantum states.
Layered systems such as MnBi2Te4/Cr2Ge2Te6 and Td-MoTe2 provide tunable interfaces for engineering magnetic exchange, inversion asymmetry, and interfacial superconducting transport.
Nanowires, nanoplates, thin-flake rings, and multi-terminal devices enable gate-tunable studies of Fermi-arc spin transport, quantum interference, Hall states, and superconducting circuits.
