Query: Janus interface in two-dimensional supersymmetric gauge theories   We study the Janus interface, a domain wall characterized by spatially
varying couplings, in two-dimensional N=(2,2) supersymmetric gauge theories on
the two-sphere. When the variations of the couplings are small enough, SUSY
localization in the Janus background gives an analytic continuation of the
sphere partition function. This directly demonstrates that the interface
entropy is proportional to the quantity known as Calabi's diastasis, as
originally shown by Bachas et al. When the variations are not small, we propose
that an analytic continuation of the sphere partition function coincides with
the Janus partition function. We give a prescription for performing such
analytic continuation and computing monodromies. We also point out that the
Janus partition function for the equivariant A-twist is precisely the
generating function of A-model correlation functions.
