Quantum distillation of Hilbert spaces, semi-classics and anomaly matching
Journal of High Energy Physics, 2018 A symmetry-twisted boundary condition of the path integral provides a suitable framework for the semi-classical analysis of nonperturbative quantum field theories (QFTs), and we reinterpret it from the viewpoint of the Hilbert space. An appropriate twist

Emergent gauge fields and their nonperturbative effects in correlated electrons [PDF]
, 2018 The history of modern condensed matter physics may be regarded as the competition and reconciliation between Stoner's and Anderson's physical pictures, where the former is based on momentum-space descriptions focusing on long wave-length ...

Hawking radiation of extended objects
Journal of High Energy Physics, 2020 We compute the effects on the temperature and precise spectrum of Hawking radiation from a Schwarzschild black hole when the emitted object is taken to be spatially extended.

Gentle introduction to rigorous Renormalization Group: a worked fermionic example
Journal of High Energy Physics, 2021 Much of our understanding of critical phenomena is based on the notion of Renormalization Group (RG), but the actual determination of its fixed points is usually based on approximations and truncations, and predictions of physical quantities are often of

Effects of nonperturbative improvement in quenched hadron spectroscopy [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 We discuss a comparative analysis of unimproved and nonperturbatively improved quenched hadron spectroscopy, on a set of 104 gauge configurations, at beta=6.2. We also present here our results for meson decay constants, including the constants f_D and f_Ds in the charm-quark region.

Quantum unitary dynamics of a charged fermionic field and Schwinger effect
Journal of High Energy Physics, 2021 In quantum field theory, particle creation occurs, in general, when an intense external field, such as an electromagnetic field, breaks time translational invariance. This leads to an ambiguity in the definition of the vacuum state.

Hadronic corrections to μ-e scattering at NNLO with space-like data
Journal of High Energy Physics, 2019 The Standard Model prediction for μ-e scattering at Next-to-Next-to-Leading Order (NNLO) contains non-perturbative QCD contributions given by diagrams with a hadronic vacuum polarization insertion in the photon propagator.

High-energy QCD: Interplay of nonperturbative and perturbative effects [PDF]
, 2015 Soft interaction is an unavoidable participant of every hard process at high energies. Although the factorisation theorems allow to separate the hard and soft parts of the interaction, in many instances (not covered by the theorems) factorisation is ...
