Direct Terrestrial Test of Lorentz Symmetry in Electrodynamics to 10
M. Nagel, S. R. Parker, E. V. Kovalchuk +5
Lorentz symmetry is a foundational property of modern physics, underlying the standard model of particles and general relativity. It is anticipated that these two theories are low…
Next-to-Leading Order Transport Coefficients from the Four-Particle Irreducible Effective Action
M. E. Carrington, E. Kovalchuk
Transport coefficients can be obtained from 2-point correlators using the Kubo formulae. It has been shown that the full leading order result for electrical conductivity and (QCD)…
Leading Order QCD Shear Viscosity from the 3PI Effective Action
M. E. Carrington, E. Kovalchuk
In this article we calculate the leading order shear viscosity in QCD using the resummed 3PI effective action. We work to 3-loop order in the effective action. We show that the int…
Leading Order QED Electrical Conductivity from the 3PI Effective Action
M. E. Carrington, E. Kovalchuk
In this article we study the electrical conductivity in QED using the resummed 3PI effective action. We work to 3-loop order in the effective action. We show that the resulting exp…
QED Electrical Conductivity using the 2PI Effective Action
M. E. Carrington, E. Kovalchuk
In this article we calculate the electrical conductivity in QED using the 2PI effective action. We use a modified version of the usual 2PI effective action which is defined with re…
