The Parma Polyhedra Library: Toward a Complete Set of Numerical Abstractions for the Analysis and Verification of Hardware and Software Systems
Roberto Bagnara, Patricia M. Hill, Enea Zaffanella
Since its inception as a student project in 2001, initially just for the handling (as the name implies) of convex polyhedra, the Parma Polyhedra Library has been continuously impro…
Resummed Mass Distribution for Jets Initiated by Massive Quarks
Ugo Aglietti, Leonardo Di Giustino, Giancarlo Ferrera +1
We resum the invariant mass distribution of jets initiated by massive quarks in next-to-leading logarithmic approximation and beyond in heuristic way. We find that the inclusion of…
Ground-State Fidelity and Bipartite Entanglement in the Bose-Hubbard Model
Pierfrancesco Buonsante, Alessandro Vezzani
We analyze the quantum phase transition in the Bose-Hubbard model borrowing two tools from quantum-information theory, i.e. the ground-state fidelity and entanglement measures. We…
Mean-field phase diagram for Bose-Hubbard Hamiltonians with random hopping
P. Buonsante, F. Massel, V. Penna +1
The zero-temperature phase diagram for ultracold Bosons in a random 1D potential is obtained through a site-decoupling mean-field scheme performed over a Bose-Hubbard (BH) Hamilton…
High-loop perturbative renormalization constants for Lattice QCD (I): finite constants for Wilson quark currents
F. Di Renzo, V. Miccio, L. Scorzato +1
We present a high order perturbative computation of the renormalization constants Z_V, Z_A and of the ratio Z_P/Z_S for Wilson fermions. The computational setup is the one provided…
Revisiting the Froehlich-type transformation when degenerate states are present
M. Acquarone, C. I. Ventura
We focus on the definition of the unitary transformation leading to an effective second order Hamiltonian, inside degenerate eigensubspaces of the non-perturbed Hamiltonian. We sha…
