Metamagnetism in UTe2: the roles of itinerancy and localization
Theodore I. Weinberger, Daniel Shaffer, Zheyu Wu +12
The metamagnetic transition in UTe plays a key role in stabilizing two enigmatic field-induced superconducting phases. One of these phases (SC2) is truncated by the transition,…

Superconductivity near two-dimensional Van Hove singularities: a determinant quantum Monte Carlo study
Gustav Romare, Daniel Shaffer, Alex Levchenko +2
The superconducting transition temperature of the two-dimensional attractive Hubbard model is computed in the vicinity of both ordinary (logarithmic) and higher-order (power-…
