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…

Entanglement of low-energy excitations in Conformal Field Theory
Francisco Castilho Alcaraz, Miguel Ibanez Berganza, German Sierra
In a quantum critical chain, the scaling regime of the energy and momentum of the ground state and low lying excitations are described by conformal field theory (CFT). The same hol…
