Pairing near the boundary of a box-shaped trap in the BEC-BCS crossover
Kelly R. Patton, Daniel E. Sheehy
We study pairing of attractively interacting fermions confined to a box-shaped trap. In contrast to the infinite translationally-invariant case, where the local pairing order is sp…

Strong-coupling superconductivity near Gross-Neveu quantum criticality in Dirac systems
Veronika C. Stangier, Daniel E. Sheehy, Jörg Schmalian
We study two-dimensional massless Dirac fermions at neutrality, coupled to bosonic modes through a Yukawa interaction. We then examine the intriguing possibility that such a system…

Superconductivity of Incoherent Electrons near the Relativistic Mott Transition in Twisted Dirac Materials
Veronika C. Stangier, Mathias S. Scheurer, Daniel E. Sheehy +1
We demonstrate that superconductivity driven by strong quantum-critical fluctuations can emerge near relativistic Mott transitions in twisted two-dimensional materials, taking on a…
