Global anomalies in 8d supergravity
Journal of High Energy Physics, 2022 We study gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. Possible global gauge anomalies are classified by spin bordism groups Ω 9 spin BG $$ {\varOmega}_9^{\mathrm{spin}}(BG) $$ which we determine by ...

Chiral torsional effects in anomalous fluids in thermal equilibrium
Journal of High Energy Physics, 2021 Using the similarity between spacetime torsion and axial gauge couplings, we study torsional contributions to the equilibrium partition function in a stationary background.

Boundary string current & Weyl anomaly in six-dimensional conformal field theory [PDF]
Journal of High Energy Physics, 2019 AbstractIt was recently discovered that for a boundary system in the presence of a background magnetic field, the quantum fluctuation of the vacuum would create a non-uniform magnetization density for the vacuum and a magnetization current is induced in the vacuum [1].

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 ...

BRST-BFV analysis of anomalies in bosonic string theory interacting with background gravitational field [PDF]
Physics Letters B, 1995 The general BRST-BFV analysis of anomaly in the string theory coupled to background fields is carried out. An exact equation for c-valued symbol of anomaly operator is found and structure of its solutions is studied.

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.

On the associativity anomaly in open string field theory
Physics Letters B, 1987 Abstract The associativity anomaly in the star algebra of the open bosonic string is demonstrated by a simple oscillator calculation. In an associative algebra, formal arguments require that the “half string” BRST operator QL be nilpotent; however, we show that associativity is actually violated by computing QL2 in an explicit operator representation

Constraints on chiral operators in N=2 SCFTs [PDF]
, 2014 : We study certain higher-spin chiral operators in (formula presented)(formula presented) superconformal field theories (SCFTs). In Lagrangian theories, or in theories related to Lagrangian theories by generalized Argyres-Seiberg-Gaiotto duality (“type A”
