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.

Comments on the Atiyah-Patodi-Singer index theorem, domain wall, and Berry phase
Journal of High Energy Physics, 2021 It is known that the Atiyah-Patodi-Singer index can be reformulated as the eta invariant of the Dirac operators with a domain wall mass which plays a key role in the anomaly inflow of the topological insulator with boundary.

SPACETIME OR QUANTUM PARTICLES: THE ONTOLOGY OF QUANTUM GRAVITY? [PDF]
, 1996 The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory

Anomalous currents and constitutive relations of a chiral hadronic superfluid
Journal of High Energy Physics, 2019 The anomalous currents of two-flavor chiral nuclear matter in the presence of chiral imbalance are computed, using recently developed methods exploiting generalized transgression, which facilitates the evaluation of both the equilibrium partition ...

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 ...

Anomaly and double copy in quantum self-dual Yang-Mills and gravity
Journal of High Energy Physics, 2023 Recent works have explored how scattering amplitudes in quantum self-dual Yang-Mills theory and self-dual gravity can be interpreted as resulting from an anomaly, as first proposed by W. Bardeen.

’t Hooft anomalies and boundaries
Journal of High Energy Physics, 2018 We argue that there is an obstruction to placing theories with ’t Hooft anomalies on manifolds with a boundary, unless the symmetry associated with the anomaly can be represented as a non-invariance under an Abelian transformation.

Boundary conformal anomalies on hyperbolic spaces and Euclidean balls
Journal of High Energy Physics, 2017 We compute conformal anomalies for conformal field theories with free conformal scalars and massless spin 1/2 fields in hyperbolic space ℍ d and in the ball Bd $$ {\mathbb{B}}^d $$, for 2≤d≤7. These spaces are related by a conformal transformation.

Anomalies in String-inspired Non-local Extensions of QED [PDF]
, 2023 We investigate anomalies in the class of non-local field theories that have been proposed as an ultraviolet completion of 4-D Quantum Field Theory (QFT) with generalizing the kinetic energy operators to an infinite series of higher derivatives inspired ...

Weyl fermions in a non-abelian gauge background and trace anomalies
Journal of High Energy Physics, 2019 We study the trace and chiral anomalies of Weyl fermions in a non-abelian gauge background in four dimensions. Using a Pauli-Villars regularization we identify the trace anomaly, proving that it can be cast in a gauge invariant form, even in the presence
