The axion quality problem: global symmetry breaking and wormholes
Journal of High Energy Physics, 2021 Continuous global symmetries are expected to be broken by gravity, which can lead to important phenomenological consequences. A prime example is the threat that this poses to the viability of the Peccei-Quinn solution to the strong CP problem.

Journal of High Energy Physics, 2021 We study neutral fermions pair creation with anomalous magnetic moment from the vacuum by time-independent magnetic-field inhomogeneity as an external background. We show that the problem is technically reduced to the problem of charged-particle creation

Exploring the θ-vacuum structure in the functional renormalization group approach
Journal of High Energy Physics, 2022 We investigate the θ-vacuum structure and the ’t Hooft anomaly at θ = π in a simple quantum mechanical system on S 1 to scrutinize the applicability of the functional renormalization group (fRG) approach.

Enhanced nonperturbative effects through the collinear anomaly. [PDF]
, 2014 We show that nonperturbative effects are logarithmically enhanced for transverse-momentum-dependent observables such as qT spectra of electroweak bosons in hadronic collisions and jet broadening at e+ e- colliders.

Regularization in nonperturbative extensions of effective field theory
Physical Review D, 2022 The process of renormalisation in nonperturbative Hamiltonian Effective Field Theory (HEFT) is examined in the $Δ$-resonance scattering channel. As an extension of effective field theory incorporating the Lüscher formalism, HEFT provides a bridge between the infinite-volume scattering data of experiment and the finite-volume spectrum of energy ...

Nonperturbative versus perturbative effects in generalized parton distributions [PDF]
, 2005 Generalized parton distributions (GPDs) are studied at the hadronic (nonperturbative) scale within different assumptions based on a relativistic constituent quark model.

Unitary quantization of a scalar charged field and Schwinger effect
Journal of High Energy Physics, 2020 Quantum field theory in curved spacetimes suffers in general from an infinite ambiguity in the choice of Fock representation and associated vacuum. In cosmological backgrounds, the requirement of a unitary implementation of the field dynamics in the ...

Nonperturbative effects in a rapidly expanding quark gluon plasma [PDF]
, 2002 Within first-order phase transitions, we investigate pretransitional effects due to the nonperturbative, large-amplitude thermal fluctuations which can promote phase mixing before the critical temperature is reached from above.
