General covariant xp models and the Riemann zeros
German Sierra
We study a general class of models whose classical Hamiltonians are given by H = U(x) p + V(x)/p, where x and p are the position and momentum of a particle moving in one dimension,…

The H=xp model revisited and the Riemann zeros
German Sierra, Javier Rodriguez-Laguna
Berry and Keating conjectured that the classical Hamiltonian H = xp is related to the Riemann zeros. A regularization of this model yields semiclassical energies that behave, in av…
