Difference Equations: from Berry Connections to the Coulomb Branch

Andrea E. V. Ferrari, Daniel Zhang

In recent work, we demonstrated that a spectral variety for the Berry connection of a 2d $N = (2, 2)$ GLSM with KÃ¤hler vacuum moduli space $X$ and abelian flavour symmetry…

On Spectral Data for $(2, 2)$ Berry Connections, Difference Equations & Equivariant Quantum Cohomology

Andrea E. V. Ferrari, Daniel Zhang

We study supersymmetric Berry connections of 2d $N = (2, 2)$ gauged linear sigma models (GLSMs) quantized on a circle, which are periodic monopoles, with the aim to provide…

Berry Connections for 2d $(2, 2)$ Theories, Monopole Spectral Data & (Generalised) Cohomology Theories

Andrea E. V. Ferrari, Daniel Zhang

We study Berry connections for supersymmetric ground states of 2d $N = (2, 2)$ GLSMs quantised on a circle, which are generalised periodic monopoles. Periodic monopole solut…
