Benjamin Ezekiel Feldman

Benjamin Ezekiel Feldman serves as Assistant Professor of Physics at Stanford University, where he leads experimental research on quantum phenomena in nanoscale materials. His work bridges fundamental condensed matter physics with cutting-edge device engineering.

His academic foundation includes:

• M.S. in Physics from Haverford College (2007)
• Ph.D. in Physics from Harvard University (2013)

The Feldman Lab pioneers studies of correlated electronic states and topological phenomena in van der Waals heterostructures, utilizing advanced scanning probe microscopy and transport measurements. Research emphasizes magic-angle graphene systems, twisted transition metal dichalcogenides like WSe₂, and moiré lattice physics, with particular focus on quantum phase transitions, spin-valley coupling, and emergent insulating states under magnetic fields.

Analysis of his 2022-2024 publications reveals a concentrated investigation of topological band structures in 2D quantum materials, where twist angle serves as a precise tuning parameter for electronic correlations. Key trends include direct imaging of spin skyrmions, mapping of Hofstadter spectra in semiconductor lattices, and characterization of anomalous Landau level gaps near magnetic critical points.

His accolades include:

• Sloan Research Fellowship (2019)
• Terman Fellowship (2018)
• NSF CAREER Award (2023)

Feldman has successfully mentored eight graduate students through PhD completion or candidacy, including Jiachen Yu (2023), Jesse Hoke and Carlos Kometter (2024), with current advisees pursuing quantum transport in novel heterostructures. His research is funded through the NSF CAREER grant for tunable correlated states in van der Waals systems and Gordon and Betty Moore Foundation support via the EPiQS Young Investigator Network.

The lab operates state-of-the-art cryogenic facilities including custom dry dilution refrigerators for sub-10mK scanning probe experiments, fostering collaborations across Stanford and international institutions to engineer topological quantum devices with potential applications in fault-tolerant quantum computing.
