Journal of High Energy Physics, 2022 We study nondissipative transport induced by the Nieh-Yan anomaly. After computing the torsional terms in the equilibrium partition function using transgression, we find the constitutive relations for the covariant axial-vector, heat, stress, and spin ...

Chiral kinetic theory from effective field theory revisited
Journal of High Energy Physics, 2019 We revisit the chiral kinetic equation from high density effective theory approach, finding a chiral kinetic equation differs from counterpart derived from field theory in high order terms in the O(1/μ) expansion, but in agreement with the equation ...

Zilch vortical effect for fermions
Journal of High Energy Physics, 2021 We consider the notion of zilch current that was recently discussed in the literature as an alternative helicity measure for photons. Developing this idea, we suggest the generalization of the zilch for the systems of fermions.

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.

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 ...

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,

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.

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.

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.
