Effective theories and non-minimal couplings in low-dimensional systems
M. G. Campos, L. P. R. Ospedal
Dimensionality aspects of non-minimal electromagnetic couplings are investigated. By means of the Foldy-Wouthuysen transformation, we attain (non-)relativistic interactions related…
Integrability and scattering of the boson field theory on a lattice
Manuel Campos, German Sierra, Esperanza Lopez
A free boson on a lattice is the simplest field theory one can think of. Its partition function can be easily computed in momentum space. However, this straightforward solution hid…
Quantum corrected gravitational potential beyond monopole-monopole interactions
G. P. de Brito, M. G. Campos, L. P. R. Ospedal +1
We investigate spin- and velocity-dependent contributions to the gravitational inter-particle potential. The methodology adopted here is based on the expansion of the effective act…
