The role of long distance contribution to the in the Standard Model
Massimo Ladisa, Pietro Santorelli
We investigate rare semileptonic by looking at the long distance contributions. Our analysis is limited to the very small values of physical accessible r…
Momentum distribution and Compton profile by the ab initio GW approximation
Valerio Olevano, Andrey Titov, Massimo Ladisa +3
We present two possible approaches to calculate the momentum distribution n(p) and the Compton profile within the framework of the ab initio GW approximation on the self-energy. Th…
On aspects of self-consistency in the Dyson-Schwinger approach to QED and λ(ϕ^\star ϕ)^2 theories
Roberto Casalbuoni, Massimo Ladisa, Valerio Olevano
We investigate some aspects of the self-consistency in the Dyson-Schwinger approach to both the QED and the self-interacting scalar field theories. We prove that the set of the Dys…
Condensed matter many-body theory in relativistic covariant form
Valerio Olevano, Massimo Ladisa
We present a relativistic covariant form of many-body theory. The many-body covariant Lagrangian is derived from QED by integrating out the internal non-quantized electromagnetic f…
Ab initio GW many-body effects in graphene
P. E. Trevisanutto, C. Giorgetti, L. Reining +2
We present an {\it ab initio} many-body GW calculation of the self-energy, the quasiparticle band plot and the spectral functions in free-standing undoped graphene. With respect to…
Folding a 2-D powder diffraction image into a 1-D scan: a new procedure
Antonio Cervellino, Cinzia Giannini, Antonietta Guagliardi +1
A new procedure aiming at folding a powder diffraction 2-D into a 1-D scan is presented. The technique consists of three steps: tracking the beam centre by means of a Simulated Ann…
