Relating ’t Hooft anomalies of 4d pure Yang-Mills and 2d ℂℙ N− 1 model
Journal of High Energy Physics, 2018 It has recently been shown that a center-twisted compactification of the four-dimensional pure SU(N) Yang-Mills theory on a three-torus gives rise to the twodimensional ℂℙ N− 1-model on a circle with a flavor-twisted boundary condition.

Relativistic hydrodynamics with the parity anomaly
Journal of High Energy Physics, 2022 We consider the hydrodynamic regime of a 2+1 dimensions QFT with the parity anomaly. Beyond the known constraints from positivity of entropy production, we show that the anomaly inflow mechanism, from a corresponding bulk SPT phase, together with ...

Non-invertible Gauss law and axions
Journal of High Energy Physics, 2023 In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries.

The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills [PDF]
Nuclear Physics B, 1994 Many field theories of physical interest have configuration spaces consisting of disconnected components. Quantum mechanical amplitudes are then expressed as sums over these components. We use the Faddeev-Popov approach to write the terms in this topological expansion as moduli space integrals. A cut-off is needed when these integrals diverge.

Journal of High Energy Physics, 2018 The linearized Einstein equation describing graviton propagation through a chiral medium appears to be helicity dependent. We analyze features of the corresponding spectrum in a collision-less regime above a flat background. In the long wave-length limit,

Scale anomalies, states, and rates in conformal field theory
Journal of High Energy Physics, 2017 This paper presents two methods to compute scale anomaly coefficients in conformal field theories (CFTs), such as the c anomaly in four dimensions, in terms of the CFT data.

Cancellation of the Lorentz anomaly of string field theory in light-cone gauge
Nuclear Physics B, 1990 Abstract We study the path-integral measure of string fields in the bosonic open-closed interacting string field theory in light-cone gauge. The Lorentz anomaly of the path-integral measure cancels the Lorentz non-invariant terms of the classical string field action. Thus the theory is shown to be Lorentz invariant at the one-loop level. The one-loop

Graviton scattering and a sum rule for the c anomaly in 4D CFT
Journal of High Energy Physics, 2018 4D CFTs have a scale anomaly characterized by the coefficient c, which appears as the coefficient of logarithmic terms in momentum space correlation functions of the energy-momentum tensor.

6D anomaly-free matter spectrum in F-theory on singular spaces
Journal of High Energy Physics, 2022 In this paper we study the 6d localized charged matter spectrum of F-theory directly on a singular elliptic Calabi-Yau 3-fold, i.e. without smoothing via resolution or deformation of the entire fibration.

Non-Abelian anomalous (super)fluids in thermal equilibrium from differential geometry
Journal of High Energy Physics, 2018 We apply differential geometry methods to the computation of the anomaly-induced hydrodynamic equilibrium partition function. Implementing the imaginary-time prescription on the Chern-Simons effective action on a stationary background, we obtain general ...
