The computation of observables in general interacting theories, be them quantum
mechanical, field, gauge or string theories, is a non-trivial problem which in many cases can …

We present exact results for partition functions of Jackiw-Teitelboim (JT) gravity on two-
dimensional surfaces of arbitrary genus with an arbitrary number of boundaries. The …

We perturbatively compute the Polyakov loop potential at high temperature with finite
imaginary angular velocity. This imaginary rotation does not violate the causality, and the …

It is widely expected that at sufficiently high temperatures order is always lost, eg, magnets
lose their ferromagnetic properties. We pose the question of whether this is always the case …

A bstract Anomaly matching constrains low-energy physics of strongly-coupled field
theories, but it is not useful at finite temperature due to contamination from high-energy …

We discuss the SU (3)/[U (1)× U (1)] nonlinear sigma model in 1+ 1D and, more broadly, its
linearized counterparts. Such theories can be expressed as U (1)× U (1) gauge theories and …

We show that $2 $ d adjoint QCD, an $ SU (N) $ gauge theory with one massless adjoint
Majorana fermion, has a variety of mixed't Hooft anomalies. The anomalies are derived …

A bstract This work examines non-perturbative dynamics of a 2-dimensional QFT by using
discrete't Hooft anomaly, semi-classics with circle compactification and bosonization. We …

A bstract We consider a class of quantum field theories and quantum mechanics, which we
couple to ℤ N topological QFTs, in order to classify non-perturbative effects in the original …

We explore the existence of conformal field theories that persistently break a global
symmetry at finite temperature. We identify vector models in (3-ε) spatial dimensions that …
