Abstract

This chapter presents a high-level description of a suite of programs denoted by the acronym OCEAN (Obtaining Core Excitation spectra ab initio and with NBSE), where NBSE denotes the underlying NIST Bethe-Salpeter Equation program. The main computational steps, physical approximations made and overall scope of the required user input are discussed. Several examples of calculation results are presented for a variety of systems. We also discuss future improvements and extensions that are being considered at this time, and discuss how to access the program and its extensive documentation.
