Jonathan R. Friedman

Jonathan R. Friedman is an Adjunct Professor of Physics at the Department of Physics and Astronomy at Amherst College. He holds a laboratory (Merrill 117) and office (Merrill 119) in the Merrill Science Center. His research focuses on quantum phenomena in nanoscale systems, particularly single-molecule magnets, quantum tunneling of magnetization, and the interplay of quantum mechanics with macroscopic systems. He has made significant contributions to understanding geometric phase effects in molecular magnets and photon-induced magnetic transitions.

Research Interests: Friedman’s work spans condensed matter physics and quantum mechanics, with a focus on probing quantum effects in nanomaterials such as Mn₁₂ and Fe₈ single-molecule magnets. His studies include magnetic anisotropy, tunneling dynamics, and the application of quantum principles to macroscopic devices. He has pioneered techniques like electron spin resonance and microwave cavity coupling to study these systems.

Awards:

• 2002 Agilent Technologies Europhysics Prize (for condensed matter physics)
• 2002 Alfred P. Sloan Research Fellowship
• 2005 NSF CAREER Award

Advancing Science: Friedman’s lab develops instrumentation, such as superconducting resonators for precise measurements. His work has been highlighted in Scientific American, Physics World, and the New York Times. He has supervised numerous student theses and collaborates with institutions like the University of Massachusetts.

Labs/Teams: His research leverages state-of-the-art facilities, including the Quantum Design PPMS for material characterization and custom microwave instrumentation.
