Excitationsfilters
Excitationsfilters are a class of algorithms used in computational chemistry and materials science to filter out unwanted electronic excitations from a system. These excitations can arise from various sources, including thermal fluctuations, electronic correlations, and external perturbations. The primary goal of an excitationsfilter is to isolate and analyze the relevant excitations that are of interest for a particular study, such as optical properties, charge transfer processes, or electronic structure.
One common application of excitationsfilters is in the calculation of excited-state properties using time-dependent density functional
Another use case for excitationsfilters is in the study of strongly correlated electron systems, where the
In summary, excitationsfilters are valuable tools in the computational study of electronic excitations. By selectively filtering
