Classical helium atom with radiation reaction.
Camelio G, Carati A, Galgani L. Camelio G, et al. Among authors: carati a. Chaos. 2012 Jun;22(2):023111. doi: 10.1063/1.4703945. Chaos. 2012. PMID: 22757518
Relaxation properties in classical diamagnetism.
Carati A, Benfenati F, Galgani L. Carati A, et al. Chaos. 2011 Jun;21(2):023134. doi: 10.1063/1.3594580. Chaos. 2011. PMID: 21721776
In the present paper, we study numerically the relaxation to equilibrium in a modified Bohr model, which is mathematically equivalent to a billiard with obstacles, immersed in a magnetic field that is adiabatically switched on. ...Depending on the values of t …

On the energy transfer to small scales in a discrete model of one-dimensional turbulence.
Carati A, Galgani L, Santolini F. Carati A, et al. Chaos. 2009 Jun;19(2):023123. doi: 10.1063/1.3156729. Chaos. 2009. PMID: 19566258
We consider a discrete one-dimensional model that was investigated numerically by Daumont and Peyrard [Chaos 13, 624 (2003)] as a model for turbulence in fluids, i.e., for the energy transfer from large to small scales. ...

The Fermi-Pasta-Ulam problem as a challenge for the foundations of physics.
Carati A, Galgani L, Giorgilli A. Carati A, et al. Chaos. 2005 Mar;15(1):15105. doi: 10.1063/1.1861264. Chaos. 2005. PMID: 15836282
The Fermi-Pasta-Ulam (FPU) problem is discussed in connection with its physical relevance, and it is shown how apparently there exist only two possibilities: either the FPU problem is just a curiosity, or it has a fundamental role for the foundations of physics, cas …

Transition from order to chaos, and density limit, in magnetized plasmas.
Carati A, Zuin M, Maiocchi A, Marino M, Martines E, Galgani L. Carati A, et al. Chaos. 2012 Sep;22(3):033124. doi: 10.1063/1.4745851. Chaos. 2012. PMID: 23020463
Analog of Planck's formula and effective temperature in classical statistical mechanics far from equilibrium.
Carati A, Galgani L. Carati A, et al. Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 May;61(5A):4791-4. doi: 10.1103/physreve.61.4791. Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000. PMID: 11031519
We study the statistical mechanics very far from equilibrium for a classical system of harmonic oscillators colliding with point particles (mimicking a heat reservoir), for negligible initial energies of the oscillators. ...This requires using Einstein's relation be …

Fermi-Pasta-Ulam phenomenon for generic initial data.
Carati A, Galgani L, Giorgilli A, Paleari S. Carati A, et al. Phys Rev E Stat Nonlin Soft Matter Phys. 2007 Aug;76(2 Pt 1):022104. doi: 10.1103/PhysRevE.76.022104. Epub 2007 Aug 24. Phys Rev E Stat Nonlin Soft Matter Phys. 2007. PMID: 17930091
Indications are given that such a nonmixing property survives in the thermodynamic limit. It is left as an open problem whether mixing actually occurs, i.e., whether the autocorrelations vanish as time tends to infinity....

Lévy flights in the Landau-Teller model of molecular collisions.
Carati A, Galgani L, Pozzi B. Carati A, et al. Phys Rev Lett. 2003 Jan 10;90(1):010601. doi: 10.1103/PhysRevLett.90.010601. Epub 2003 Jan 10. Phys Rev Lett. 2003. PMID: 12570598
We consider the Landau-Teller model, which is a prototype for the exchanges of energy, in molecular collisions, between internal degrees of freedom and those of the center of mass. We show that the statistics of the energy exchanges computed through the dynamics over a

Electronic trajectories in atomic physics: The chemical bond in the H2 + ion.
Carati A, Galgani L, Gangemi F, Gangemi R. Carati A, et al. Chaos. 2020 Jun;30(6):063109. doi: 10.1063/5.0002703. Chaos. 2020. PMID: 32611072 Free article.
