On the wrapping correction to single magnon energy in twisted N=4 SYM
Matteo Beccaria, Gian Fabrizio De Angelis
We apply Zeilberger summation to derive a closed formula for the wrapping correction to one-impurity states in the su(2) sector of the beta-deformed N=4 SYM theory at beta=1/2. As…
The scaling function at strong coupling from the quantum string Bethe equations
Matteo Beccaria, Gian Fabrizio De Angelis, Valentina Forini
We study at strong coupling the scaling function describing the large spin anomalous dimension of twist two operators in super Yang-Mills theory. In the spirit of AdS/…
Highest states in light-cone superstring
Matteo Beccaria, Gian Fabrizio De Angelis, Luigi Del Debbio +1
We study the highest states in the compact rank-1 sectors of the AdS5 X S5 superstring in the framework of the recently proposed light cone Bethe Ansatz equations. In the su(1|1) s…
Evolution of fermionic systems as an expectation over Poisson processes
Matteo Beccaria, Carlo Presilla, Gian Fabrizio De Angelis +1
We derive an exact probabilistic representation for the evolution of a Hubbard model with site- and spin-dependent hopping coefficients and site-dependent interactions in terms of…
An exact representation of the fermion dynamics in terms of Poisson processes and its connection with Monte Carlo algorithms
Matteo Beccaria, Carlo Presilla, Gian Fabrizio De Angelis +1
We present a simple derivation of a Feynman-Kac type formula to study fermionic systems. In this approach the real time or the imaginary time dynamics is expressed in terms of the…
Berezin Integrals and Poisson Processes
G. F. De Angelis, G. Jona-Lasinio, V. Sidoravicius
We show that the calculation of Berezin integrals over anticommuting variables can be reduced to the evaluation of expectations of functionals of Poisson processes via an appropria…
