Understanding Traffic Jams Using Lindblad Superoperators
Andrea Nava, Domenico Giuliano, Alessandro Papa +1
We propose a model to simulate different traffic-flow conditions in terms of quantum graphs hosting an (N+1)-level dot at each site. Our model allows us to keep track of the type a…

Numerical Evidence for the Haldane Conjecture
B. Alles, A. Papa
The Haldane conjecture, when applied to the Heisenberg O(3) model with a θterm in two dimensions, states that the correlation length ξdiverges when θapproaches π. To verify this co…

Mass gap in the 2D O(3) non-linear sigma model with a theta=pi term
B. Alles, A. Papa
By analytic continuation to real theta of data obtained from numerical simulation at imaginary theta we study the Haldane conjecture and show that the O(3) non-linear sigma model w…
