Dynamical entanglement and chaos: the case of Rydberg molecules
M Lombardi, A Matzkin
A Rydberg molecule is composed of an outer electron that collides on the residual ionic core. Typical states of Rydberg molecules display entanglement between the outer electron an…
Variational Estimates using a Discrete Variable Representation
M. Lombardi, P. Barletta, A. Kievsky
The advantage of using a Discrete Variable Representation (DVR) is that the Hamiltonian of two interacting particles can be constructed in a very simple form. However the DVR Hamil…
Unified theory of bound and scattering molecular Rydberg states as quantum maps
Barbara Dietz, Maurice Lombardi, Thomas H Seligman
Using a representation of multichannel quantum defect theory in terms of a quantum Poincaré map for bound Rydberg molecules, we apply Jung's scattering map to derive a generalized…
A Diffusion Model for Classical Chaotic Compound Scattering
F. Leyvraz, M. Lombardi, T. H. Seligman
We consider the classical map proposed previously to be the exact classical analogue of Rydberg Molecules calculated with the approximations relevant to the multi-channel quantum d…
Multichannel Quantum Defect Theory: a Quantum Poincare Map
F. Leyvraz, R. A. Mendez-Sanchez, M. Lombardi +1
The multichannel quantum defect theory (MQDT) can be reinterpreted as a quantum Poincare map in representation of angular momentum. This has two important implications: we have a p…
Measurements of the reaction of antiproton annihilation at rest at three hydrogen target densities
OBELIX Collaboration, V. Alberico, A. Bertin
The proton-antiproton annihilation at rest into the final state was measured for three different target densities: liquid hydrogen, gaseous hydrogen at NTP and at a low pressu…
