Nonperturbative analysis of nuclear shape effects on the bound electron g factor [PDF]
Physical Review A, 2018 The theory of the g factor of an electron bound to a deformed nucleus is considered non-perturbatively and results are presented for a wide range of nuclei with charge numbers from Z=16 up to Z=98.

Nonperturbative Quantum Electrodynamics in the Cherenkov Effect [PDF]
Physical Review X, 2018 Quantum electrodynamics (QED) is one of the most precisely tested theories in the history of science, giving accurate predictions to a wide range of experimental observations. Recent experimental advances allow for the ability to probe physics on extremely short attosecond timescales, enabling ultrafast imaging of quantum dynamics.

Quantum-induced trans-Planckian energy near horizon
Journal of High Energy Physics, 2018 We study the loop effects on the geometry and boundary conditions of several black hole spacetimes one of which is time-dependent and analyze the energy measured by an infalling observer near their horizons.

States of low energy in the Schwinger effect
Journal of High Energy Physics, 2023 States of low energy in cosmology minimise the energy density when smeared in a chosen time interval. We extend such construction to generic homogeneous (possibly anisotropic) particle creation settings.

Constraining Nonperturbative Strong-Field Effects in Scalar-Tensor Gravity by Combining Pulsar Timing and Laser-Interferometer Gravitational-Wave Detectors [PDF]
, 2017 Pulsar timing and gravitational-wave (GW) detectors are superb laboratories to study gravity theories in the strong-field regime. Here we combine those tools to test the mono-scalar-tensor theory of Damour and Esposito-Far{e}se (DEF), which predicts ...

Simulating compact quantum electrodynamics with ultracold atoms: probing confinement and nonperturbative effects. [PDF]
Physical Review Letters, 2012 Recently, there has been much interest in simulating quantum field theory effects of matter and gauge fields. In a recent work, a method for simulating compact quantum electrodynamics (CQED) using Bose-Einstein condensates has been suggested.

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 renormalization for 2PI effective action techniques [PDF]
Annals of Physics, 2005 Nonperturbative approximation schemes based on two-particle irreducible (2PI) effective actions provide an important means for our current understanding of (non-)equilibrium quantum field theory. A remarkable property is their renormalizability, since these approximations involve selective summations to infinite perturbative orders.

Topology in full QCD at high temperature: a multicanonical approach
Journal of High Energy Physics, 2018 We investigate the topological properties of N f = 2 + 1 QCD with physical quark masses, at temperatures around 500 MeV. With the aim of obtaining a reliable sampling of topological modes in a regime where the fluctuations of the topological charge Q are
