QED positronium and the exact renormalization group
Guillermo Hansen, Roberto Trinchero
Quantum electrodynamics (QED) is studied in the framework of the exact (functional) renormalization group (ERG). This is done using an approach to these equations which employs dim…
The exact renormalization group and dimensional regularization
Roberto Trinchero
The exact renormalization group (ERG) is formulated implementing the decimation of degrees of freedom by means of a particular momentum integration measure. The definition of this…
Wilson-Fisher fixed points for any dimension
Roberto Trinchero
The critical behavior of a non-local scalar field theory is studied. This theory has a non-local quartic interaction term which involves a real power -βof the Laplacian. The parame…
Critical behaviour of a non-local ϕ^{4} field theory and asymptotic freedom
Roberto Trinchero
The critical behaviour of a non-local scalar field theory is studied. This theory has a non-local kinetic term which involves a real power 1-2αof the Laplacian. The interaction ter…
Examples of reflection positive Euclidean field theories
Roberto Trinchero
The requirement of reflection positivity(RP) for Euclidean field theories is considered. This is done for the cases of a scalar field, a higher derivative scalar field theory and t…
Holographic Wilson loops, Hamilton-Jacobi equation and regularizations
Diego Pontello, Roberto Trinchero
The minimal area for surfaces whose border are rectangular and circular loops are calculated using the Hamilton-Jacobi (HJ) equation. This amounts to solve the HJ equation for the…
