New formula for Asymptotic behavior of the Synchrotron function
Ivan Gonzalez, Daniel Salinas-Arizmendi
Synchrotron radiation plays a central role in astrophysical and high-energy processes. Its spectral description involves the synchrotron function, defined by a non-trivial integral…
A Novel Transfer Matrix Framework for Multiple Dirac Delta Potentials
Joaquín Figueroa, Ivan Gonzalez, Daniel Salinas-Arizmendi
We present an analytical framework for studying quantum tunneling through multiple Dirac delta potential barriers in one dimension. Using the transfer matrix method, we derive a cl…
A simple way to reduce the number of contours in the multi-fold Mellin-Barnes integrals
Mauricio Diaz, Ivan Gonzalez, Igor Kondrashuk +1
Mellin-Barnes integral representation of one-loop off-shell box massless diagram is five-fold by construction. On the other hand, it is known from the year 1992 that it may be redu…
The evaluation of a definite integral by the method of brackets illustrating its flexibility
Ivan Gonzalez, John Lopez Santander, Victor H. Moll
The method of brackets is an procedure to evaluate definite integrals. It is based on a small number of operational rules. The flexibility of this method is illustrated with the ev…
