Nicholas P. Breznay

Nicholas P. Breznay is an Assistant Professor in the Department of Physics at Harvey Mudd College. His research focuses on quantum materials, where collective electron interactions lead to exotic states of matter such as superconductors, spin-liquid magnets, and Anderson insulators. He conducts low-temperature experiments (≤1 K) using thin film and bulk crystal samples, exploring phenomena like charge order, spin memory, and quantum oscillations under intense electromagnetic fields.

His research group, the BrezLab, utilizes advanced tools including LHe cryostats, scanning probes, and 2D materials synthesis stations. Collaborators include Professors Matthias Wuttig (RWTH Aachen), Alex Frano (UC San Diego), and Claudia Ojeda-Aristizabal (Cal State Long Beach).

• Key research themes:
• Quantum phase transitions in disordered systems
• Electron correlations in Kitaev and cuprate superconductors
• Spintronics applications of phase-change materials
• Surface and bulk interactions in topological iridates

The BrezLab has produced significant publications on topics ranging from spin-liquid magnetism to charge order topology, as evidenced by articles in Nature, Nature Physics, Physical Review B, and Science Advances. His 2022 Nature commentary highlighted strange metal behavior in failed superconductors.

Current and former students in his lab have contributed to projects involving magnetic phase transitions, charge localization, and quantum oscillations. The lab emphasizes hands-on experimentation and modeling of fundamental properties for next-generation electronic materials.
