Continuum Double Exchange Model
J. M. Roman, J. Soto
We present a continuum model for doped manganites which consist of two species of quantum spin 1/2 fermions interacting with classical spin fields. The phase structure at zero temp…

Potential NRQED: The Positronium Case
A. Pineda, J. Soto
We discuss in detail potential NRQED (pNRQED), a previously proposed effective field theory for ultrasoft photons. The pNRQED lagrangian for the equal mass case is presented and it…

Matching at one loop for the four-quark operators in NRQCD
A. Pineda, J. Soto
The matching coefficients for the four-quark operators in NRQCD (NRQED) are calculated at one loop using dimensional regularization for ultraviolet and infrared divergences. The ma…
