2D Quantum Materials

Laboratory for Topological Quantum Matter and Computing

This is the Ben-Chuan Lin Group at the Shenzhen International Quantum Academy, a branch of Hefei National Laboratory. We develop mesoscopic quantum devices to reveal, manipulate, and understand emergent quantum degrees of freedom in correlated quantum materials.

Kagome Materials

Thin-flake RbV3Sb5 and CsV3Sb5 devices reveal how kagome geometry, topology, and electronic correlations generate nematicity, unconventional pairing, and switchable quantum states.
