A bstract A low-energy effective theory is said to be in the swampland if it does not have any
consistent UV completion inside a theory of quantum gravity. The natural question is if the …

A bstract We investigate, by means of numerical lattice simulations, the θ-dependence of the
critical deconfinement temperature of SU (N) gauge theories at large N: T c (θ)= T c (0)[1–Rθ …

We systematically study Lorentz symmetry extensions in quantum field theories (QFTs) and
their't Hooft anomalies via cobordism. The total symmetry $ G'$ can be expressed in terms of …

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 …

A bstract We study two semiclassical limits of SU (2) Yang-Mills theory on a spatial torus with
a't Hooft twist: the “femtouniverse,” where all 𝕋 3 directions are small, and deformed Yang …

A bstract We study four-dimensional gauge theories with arbitrary simple gauge group with 1-
form global center symmetry and 0-form parity or discrete chiral symmetry. We canonically …

A bstract We study an't Hooft anomaly of massless QCD at finite temperature. With the
imaginary baryon chemical potential at the Roberge-Weiss point, there is a ℤ 2 symmetry …

A bstract We study SU (N c) gauge theories with Dirac fermions in representations ℛ of
nonzero N-ality, coupled to axions. These theories have an exact discrete chiral symmetry …

A bstract Massive QCD at θ= π breaks CP spontaneously and admits domain walls whose
dynamics and phases depend on the number of flavors and their masses. We discuss these …

We investigate the relation between the realization of center symmetry and the dependence
on the topological parameter θ in SU (N) Yang-Mills theories, exploiting trace deformations …
