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…
Entanglement in an expanding toroidal Bose-Einstein condensate
Anshuman Bhardwaj, Ivan Agullo, Dimitrios Kranas +2
Recent experiments have employed rapidly expanding toroidal Bose-Einstein condensates (BECs) to mimic the inflationary expansion in the early universe. One expected signature of th…
Unruh Effect and Takagi's Statistics Inversion in Strained Graphene
Anshuman Bhardwaj, Daniel E. Sheehy
We present a theoretical study of how a spatially-varying quasiparticle velocity in honeycomb lattices, achievable using strained graphene or in engineered cold-atom optical lattic…
Andreev spectroscopy of nonhelical spin textures in topological insulators
David J. Alspaugh, Mahmoud M. Asmar, Daniel E. Sheehy +1
We study how nonhelical spin textures affect the proximity-induced superconductivity of topological insulator (TI)-superconductor (SC) interface states. In particular we calculate…
