Dirac-Harmonic Maps

Qun Chen, Juergen Jost, Jiayu Li +1

We introduce a functional that couples the nonlinear sigma model with a spinor field: $L=\int_M[|dϕ|^2+(ψ,\Dψ)]$. In two dimensions, it is conformally invariant. The critical point…

Regularity Theorems and Energy Identities for Dirac-Harmonic Maps

Qun Chen, Juergen Jost, Guofang Wang +1

We study a new set of coupled field equations motivated by the non-linear supersymmetric sigma model of quantum field theory. These equations couple a map into a Riemannian manifol…
