’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.

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 ...

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 ...

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.

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.

Quantum kinetic equation for fluids of spin-1/2 fermions
Journal of High Energy Physics, 2021 Fluid of spin-1/2 fermions is represented by a complex scalar field and a four-vector field coupled both to the scalar and the Dirac fields. We present the underlying action and show that the resulting equations of motion are identical to the ...

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

Geometric general solution to the U(1) anomaly equations
Journal of High Energy Physics, 2020 Costa et al. [Phys. Rev. Lett. 123 (2019) 151601] recently gave a general solution to the anomaly equations for n charges in a U(1) gauge theory. ‘Primitive’ solutions of chiral fermion charges were parameterised and it was shown how operations performed

Dynamical Abelianization and anomalies in chiral gauge theories
Journal of High Energy Physics, 2022 We explore the idea that in some class of strongly-coupled chiral SU(N) gauge theories the infrared dynamics might be characterized by a bifermion condensate in the ad- joint representation of the color gauge group.

Advanced Intelligent Discovery, EarlyView.Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.
