Comment to ``Quantization of FRW spacetimes in the presence of a cosmological constant and radiation''
Paolo Amore, Alfredo Aranda, Mayra Cervantes +2
The quantization of the Friedmann-Robertson-Walker spacetime in the presence of a negative cosmological constant was used in a recent paper to conclude that there are solutions tha…
Systematic Low-Energy Effective Field Theory for Electron-Doped Antiferromagnets
C. Brügger, C. P. Hofmann, F. Kämpfer +3
In contrast to hole-doped systems which have hole pockets centered at , in lightly electron-doped antiferromagnets the charged quasiparticles resid…
Renormalization of the baryon axial vector current in large-N_c chiral perturbation theory
Ruben Flores-Mendieta, Christoph P. Hofmann
The baryon axial vector current is computed at one-loop order in heavy baryon chiral perturbation theory in the large-N_c limit, where N_c is the number of colors. Loop graphs with…
Strong gravitational lensing from compact bodies: analytical results
Paolo Amore, Mayra Cervantes, Arturo De Pace +1
We develop a non--perturbative method that yields analytical expressions for the deflection angle of light in a general static and spherically symmetric metric. It is an improvemen…
On Dalgarno and Lewis Perturbation Theory for Scattering States
Paolo Amore, Francisco M. Fernandez
We apply the method of Dalgarno and Lewis to scattering states and discuss the choice of the unperturbed model in order to have a convergent perturbation series for the phase shift…
Iterative solution of differential equations
Paolo Amore, Hakan Ciftci, Francisco M. Fernandez
We discuss alternative iteration methods for differential equations. We provide a convergence proof for exactly solvable examples and show more convenient formulas for nontrivial p…
