Asymptotics of correlations in the Ising model: a brief survey
We present a brief survey of rigorous results on the asymptotic behavior of
correlations between two local functions as the distance between their support
diverges, concentrating on the Ising model on with finite-range
ferromagnetic interactions.Comment: Revised version: minor improvements, updated bibliography. Correction
of a (minor but annoying) typo. To appear in Panoramas et Synth\`ese
Theory of cooling neutron stars versus observations
We review current state of neutron star cooling theory and discuss the
prospects to constrain the equation of state, neutrino emission and superfluid
properties of neutron star cores by comparing the cooling theory with
observations of thermal radiation from isolated neutron stars.Comment: 9 pages, 4 figures, 3 tables, to appear in the proceedings of "40

A-twisted correlators and Hori dualities
The Hori-Tong and Hori dualities are infrared dualities between
two-dimensional gauge theories with supersymmetry, which
are reminiscent of four-dimensional Seiberg dualities. We provide additional
evidence for those dualities with , , and
gauge groups, by matching correlation functions of Coulomb branch operators on
a Riemann surface , in the presence of the topological -twist. The
theories studied, denoted by and , can be understood
as orbifolds of an theory. The correlators of these
theories on with are obtained by computing correlators with
-twisted boundary conditions and summing them up with weights
determined by the orbifold projection.Comment: 45 pages plus appendix; v2: updated bibliography and acknowledgement
