C18O, 13CO, and 12CO abundances and excitation temperatures in the Orion B molecular cloud: An analysis of the precision achievable when modeling spectral line within the Local Thermodynamic Equilibrium approximation
Antoine Roueff, Maryvonne Gerin, Pierre Gratier +23
CO isotopologue transitions are routinely observed in molecular clouds to probe the column density of the gas, the elemental ratios of carbon and oxygen, and to trace the kinematic…

Charge and spin inhomogeneous phases in the Ferromagnetic Kondo Lattice Model
D. J. Garcia, K. Hallberg, C. D. Batista +4
We study numerically the one-dimensional ferromagnetic Kondo lattice. This model is widely used to describe nickel and manganese perovskites. Due to the competition between double…

Electronic properties of the dimerized one-dimensional Hubbard model using lattice density-functional theory
R. Lopez-Sandoval, G. M. Pastor
The dimerized one-dimensional Hubbard model is studied in the framework of lattice density-functional theory (LDFT). The single-particle density matrix gamma_{ij} with respect to t…
