Quantum Fluids & Solids Research

Quantum fluids and solids (QFS) exhibit remarkable macroscopic quantum behaviors with no classical counterparts. Our Cryogenics Lab explores these unique properties across a broad range of topics, including quantized vortex dynamics and quantum turbulence in superfluid helium (He II), QFS-based qubits and quantum sensors, and helium cryogenic diagnostics for superconducting accelerator beamlines. We also investigate He II and other quantum materials for WIMP dark matter detection.

About Us

Our Cryogenics Lab combines advanced cryogenic platforms with state-of-the-art laser and magnet technologies to enable precision control and measurement of quantum fluids and solids. This unique experimental capability allows us to pursue research spanning fundamental quantum hydrodynamics, quantum sensing and information science, accelerator cryogenics, and particle-physics applications. We seek highly motivated students interested in hands-on experiments and interdisciplinary research at the frontier of quantum science and cryogenic engineering.
