Gregory A. Fiete

Professor Gregory A. Fiete is a faculty member in the Department of Physics at Northeastern University. His research group explores condensed matter physics with a focus on interaction effects in quantum many-body systems, spanning nanoscale electron confinement to frustrated magnetism in macroscopic samples. The group employs both numerical and non-perturbative analytical methods, often guided by experimental motivations.

Recent research emphasizes topological insulators, quantum magnetism, transition metal oxides, entanglement spectra, and the fractional quantum Hall effect. The team investigates unusual phases of matter with unexpected properties, leveraging quantum geometry and nonlinear optical responses in 2D materials.
