معرفی
William Halperin is the Orrington Lunt Professor in the Department of Physics and Astronomy at Northwestern University's Weinberg College of Arts & Sciences. His research focuses on low-temperature physics, superfluidity, and NMR studies of superconductors. He collaborates with Professor Sauls' theoretical group and maintains a crystal growth facility producing high-quality UPt3 crystals. Halperin has pioneered techniques like 17O NMR and acoustic cavity methods, and his work has been recognized with awards including the Fritz London Memorial Prize (2017) and Fellowships from the Alfred P. Sloan Foundation and the American Physical Society.
Halperin earned his PhD from Cornell University in 1975. His research explores novel phases of superfluid 3He in porous aerogel, high-Tc superconductors under extreme magnetic fields (up to 40 Tesla), and topological superconductivity in UPt3. His group's discoveries include the superfluid glass phase of 3He-A and chiral phases stabilized by anisotropic aerogels.
Key contributions span experimental and theoretical collaborations, including neutron scattering studies of UPt3 and acoustic investigations of superfluid excitations. His work bridges practical fluid confinement in porous media with fundamental superfluidity studies, demonstrating interdisciplinary impact in condensed matter physics.
