How the exchange energy can affect the power laws used to extrapolate the coupled cluster correlation energy to the thermodynamic limit

Tina N. Mihm, Laura Weiler, James J. Shepherd

Finite size error is commonly removed from coupled cluster theory calculations by extrapolations over correlation energy calculations of different system sizes (), wher…
