Analysis of the SGA method for obtaining energy spectra
Patricio Cordero, Jamil Daboul
We analyze and clarify how the SGA (spectrum generating algebra) method has been applied to different potentials. We emphasize that each energy level obtained originally by M…

Validity of the one-dimensional dissipative Boltzmann equation for point particles up to the clustering regime
Jose Miguel Pasini, Patricio Cordero
We study stationary states of a one-dimensional gas of granular point-like particles not subject to gravity between two walls at temperatures T- and T+, with T- < T+. Depending on…
