معرفی
John B. Ketterson is a Professor of Physics and Astronomy at Northwestern University, with a courtesy appointment in Electrical and Computer Engineering. His research focuses on condensed matter physics, materials science, and nanotechnology, particularly exploring superconductivity, spin dynamics, and magnetic nanostructures. He holds the Fayreweather Professorship, reflecting his academic leadership.
Key research interests include vortex dynamics in superconductors, spin-wave propagation in ferromagnetic materials, and the design of novel superconducting devices. His work bridges fundamental physics and applied technologies, such as Josephson junctions, magnetic sensors, and magnonic crystals. Recent studies emphasize nanopatterning effects on material properties and the development of heteromorphic superlattices with minimal interface defects.
Publications demonstrate a strong emphasis on experimental and theoretical investigations of magnetic and superconducting systems, including studies of Suhl instabilities, ferromagnetic resonance, and the interplay between spintronics and antiferromagnetic materials. His contributions span from nanoscale device physics to broader questions in condensed matter theory.
Ketterson’s work has been supported through collaborations in advanced nanofabrication and characterization techniques, with applications in quantum devices, energy-efficient electronics, and sensing technologies. He actively explores the intersection of material synthesis and device functionality, targeting innovations in superconducting electronics and spin-based technologies.
