WebFeb 5, 2024 · Basically, when truncation is performed at similar levels, the two methods scale the same, but the prefactor may be different - this also depends on the quality of the implementation. For reasons stated above, CC has been worked on more intensively since, say, the mid 1990s. So, CISD and CCSD scale similarly, CISDT and CCSDT would as well. WebThe CIS method has some appealing features: It is relatively fast compared to other methods; CIS can be applied to systems as large as DNA duplex oligomers. It is easy to set up; typically, the number of desired excited states and the basis set are the only quantities to be... It is possible to ...

WebThe CISD correlation energy is given by (2) and the amplitudes can be determined by the solution to the coupled set of eqations: (3) The CISD method is not size-extensive, but this problem can be overcome by making very simple modifications to the amplitude equations.
WebAs is shown in Eqs. (1) and (2) and Tables I and II, both the CCSD and TD-CISD methods can be expressed as a series of dense matrix-matrix multiplications. These spin-free CCSD equations consist of 34 tensor contractrions ranging in cost from the 3rd to the 6th power of system size. The CISD equations, which are considerably simpler, require 15 ...
