Symmetry Breaking from Monopole Condensation in QED $_{3}$

Thomas T. Dumitrescu, Pierluigi Niro, Ryan Thorngren

QED in three dimensions with an $S U (2)_{f}$ doublet $ψ^{i}$ of massless, charge-1 Dirac fermions (and no Chern-Simons term) has a $U (2) = (S U (2)_{f} \times U (1)_{m}) / Z_{2}$ symmetry…

The Smith Fiber Sequence and Invertible Field Theories

Arun Debray, Sanath K. Devalapurkar, Cameron Krulewski +3

Smith homomorphisms are maps between bordism groups that change both the dimension and the tangential structure. We give a completely general account of Smith homomorphisms, unifyi…
