Fermi gas of domain-wall Skyrmions in QCD in a strong magnetic field
Patrick Copinger, Minoru Eto, Muneto Nitta
Fermionic domain-wall Skyrmions arise in the chiral soliton lattice of two flavor chiral perturbation theory in a magnetic field as the ground state and are associated with baryons…
Scattering in strong field QED in a non-null background
Patrick Copinger, James P. Edwards, Karthik Rajeev
We examine scattering amplitudes for an arbitrary number of photons in a class of non-null background electromagnetic fields, studying tree-level and one-loop amplitudes in scalar…
Fermionic domain-wall Skyrmions of QCD in a magnetic field
Patrick Copinger, Minoru Eto, Muneto Nitta +1
The ground state of low-energy QCD matter in strong magnetic fields is either a chiral soliton lattice (CSL), a periodic array of neutral pion domain walls (chiral solitons) perpen…
In-in worldline formalism in pair creating fields
Patrick Copinger, Shi Pu
An in-in framework under Schwinger pair creating fields in strong-field quantum electrodynamics is formulated using in-out propagators in coordinate space, that have first-quantize…
Worldline Modeling of Ultra-Intense Lasers for N-photon Scattering Processes
Ivan Ahumada, Patrick Copinger, James P. Edwards +1
The modeling of present and future ultra-intense lasers demands techniques that go beyond the standard diagrammatic approach to non-perturbatively fully capture the effects of stro…
Low-energy multi-photon scattering at tree-level and one-loop order in a homogeneous electromagnetic field
Ivan Ahumada, Patrick Copinger, James P. Edwards
We study low energy photons coupled to scalar and spinor matter in the presence of an arbitrary homogeneous electromagnetic field in a first-quantised (worldline) approach. Utilisi…
