Description

Abstract Theoretical models of electron transport in condensed matter require an effective source of the Chandrasekhar H ( x , o m e g a ) function. A code providing the H ( x , o m e g a ) function has to be both accurate and very fast. The current revision of the code published earlier [A. Jablonski, Comput. Phys. Commun. 183 (2012) 1773] decreased the running time, averaged over different pairs of arguments x and omega, by a factor of more than 20. The decrease of the running time in the range of s... Title of program: CHANDRAS_v2 Catalogue Id: AEMC_v2_0 Nature of problem An attempt has been made to develop a subroutine that calculates the Chandrasekhar function with high accuracy, of at least 10 decimal places. Simultaneously, this subroutine should be very fast. Both requirements stem from the theory of electron transport in condensed matter. Versions of this program held in the CPC repository in Mendeley Data AEMC_v1_0; CHANDRAS; 10.1016/j.cpc.2012.02.022 AEMC_v2_0; CHANDRAS_v2; 10.1016/j.cpc.2012.08.020 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
