Quantum Poincare Recurrences for Hydrogen Atom in a Microwave Field
Giuliano Benenti, Giulio Casati, Giulio Maspero +1
We study the time dependence of the ionization probability of Rydberg atoms driven by a microwave field, both in classical and in quantum mechanics. The quantum survival probabilit…
Signatures of an intermediate 2d Coulomb phase at low temperatures
Giuliano Benenti, Xavier Waintal, Jean-Louis Pichard
The study of the ground state of spinless fermions in 2d disordered clusters (Phys. Rev. Lett. {\bf 83}, 1826 (1999)) has suggested the existence of a new quantum phase for interme…
Metallic phase between the Fermi glass and the Wigner crystal in two dimensions
Xavier Waintal, Giuliano Benenti, Jean-Louis Pichard
For intermediate Coulomb energy to Fermi energy ratios , spinless fermions in a two-dimensional random potential form a new quantum phase, different from the Fermi glass (weak…
Delocalized Coulomb phase in two dimensions
Xavier Waintal, Giuliano Benenti, Jean-Louis Pichard
Extending finite size scaling theory to the many body ground state, one finds that Coulomb repulsion can drive a system of spinless fermions in a random potential from the Anderson…
A new quantum phase in two dimensions
Giuliano Benenti, Xavier Waintal, Jean-Louis Pichard
For intermediate Coulomb energy to Fermi energy ratios , spinless fermions in a random potential form a new quantum phase which is different from the Fermi glass and the Wigne…
Chaotic dynamics of a classical radiant cavity
Giuliano Benenti, Giulio Casati, Italo Guarneri
The statistical properties of a classical electromagnetic field in interaction with matter are numerically investigated on a one-dimensional model of a radiant cavity, conservative…
