The aperiodic firehose instability of counter-beaming electrons in space plasmas
M. Lazar, R. A. López, P. S. Moya +2
Recent studies have revealed new unstable regimes of the counter-beaming electrons specific to hot and dilute plasmas from astrophysical scenarios. The (counter-)beaming electron f…
Catenaries and minimal surfaces of revolution in hyperbolic space
Luiz C. B. da Silva, Rafael López
We introduce the concept of extrinsic catenary in the hyperbolic plane. Working in the hyperboloid model, we define an extrinsic catenary as the shape of a curve hanging under its…
Catenaries and singular minimal surfaces in the simply isotropic space
Luiz C. B. da Silva, Rafael López
This paper investigates the hanging chain problem in the simply isotropic plane as well as its 2-dimensional analog in the simply isotropic space. The simply isotropic plane and sp…
A characterization of rotational minimal surfaces in the de Sitter space
Rafael López
The generating curves of rotational minimal surfaces in the de Sitter space $\s_1^3$ are characterized as solutions of a variational problem. It is proved that these curves are the…
Sigma basis sets: a new family of GTO basis sets for molecular calculations
Ignacio Ema, Guillermo Ramírez, Rafael López +1
A new family of Gaussian-type basis sets named sigma basis sets is presented and preliminarily tested. Sigma basis sets for H, C, N, O and P are reported and their performance is t…
