Topological Structure of Infrared QCD
J. Gamboa
We investigate the infrared structure of QCD within the adiabatic approximation, where soft gluon configurations evolve slowly compared to the fermionic modes. In this formulation,…
Topological Relics of Infrared QED in the Rayleigh-Jeans Regime
J. Gamboa
We revisit infrared Quantum Electrodynamics (QED) by reformulating the dressing of charged states in terms of a functional Berry connection. In this framework, the electron--photon…
Entanglement and Effective Field Theories
Jorge Gamboa
We investigate the emergence of geometric phases in chiral transformations within gauge theories coupled to fermions. We begin by analyzing the Schwinger model in (1+1) dimensions,…
Topology and the Infrared Structure of Quantum Electrodynamics
J. Gamboa
We study infrared divergences in quantum electrodynamics using geometric phases and the adiabatic approximation in quantum field theory. In this framework, the asymptotic \textit{i…
The Role of Berry Phases in the QCD Vacuum Structure
J. Gamboa
We revisit the origin of the vacuum angle in QCD using the adiabatic approximation combined with Fujikawa's method. By implementing a local chiral transformation and selecting…
Berry Phase in Non-Perturbative QED
J. Gamboa
We study QED in the adiabatic approximation, incorporating global topological effects associated with the Berry connection. The Berry phase accumulated by the fermionic…
