都万顺 (Wanshun DU)

Dr. Wanshun Du is an experimental condensed-matter physicist specializing in two-dimensional superconductivity, nonreciprocal quantum transport, and automated cryogenic measurement technologies.

Research Focus

Dr. Du studies superconducting quantum transport in low-dimensional quantum materials, particularly two-dimensional and strongly layered superconductors. His research centers on nonreciprocal superconductivity, the superconducting diode effect, magnetochiral anisotropy, and anisotropic vortex dynamics. He examines how inversion-symmetry breaking, spin–orbit coupling, crystalline anisotropy, reduced dimensionality, external magnetic fields, and dimensional crossover shape superconducting states and their transport responses.

He combines two-dimensional material preparation and micro- and nanodevice fabrication with cryogenic magnetotransport, nonlinear electrical measurements, symmetry analysis, and quantitative data analysis. Systematic temperature-, field-, angle-, and current-dependent measurements allow him to distinguish intrinsic nonreciprocal superconducting responses from effects associated with contacts, heating, disorder, or vortex motion, while relating device-scale transport signatures to superconducting order, spin–orbit-coupled electronic structures, and vortex pinning and motion.

These methods help identify the microscopic mechanisms behind unconventional superconductivity and nonreciprocal quantum transport. Dr. Du also develops controllable material and device platforms for studying unconventional superconducting phases and dissipationless rectification, with potential applications in low-power superconducting electronics and emerging quantum devices.

Experimental Engineering and Automation

In parallel with his fundamental research, Dr. Du develops automated and remotely accessible experimental infrastructure for low-temperature quantum-transport measurements. His work includes instrument integration, programmable control of electrical and magnetic-field parameters, synchronized operation of multiple measurement modules, automated data acquisition, real-time monitoring, and standardized data processing. He also works to improve data traceability and modularity so that measurement procedures can be reviewed, reproduced, and extended across different experiments.

By developing remote-control and workflow-automation capabilities, Dr. Du seeks to improve measurement efficiency, reproducibility, operational safety, and long-term experimental stability, particularly for multidimensional parameter scans and extended cryogenic experiments. These engineering efforts support the construction of scalable and intelligent experimental platforms for systematic studies of complex quantum materials and devices.
