Stochastic coupled cluster theory.
We describe a stochastic coupled cluster theory which represents excitation amplitudes as discrete excitors in the space of excitation amplitudes. Reexpressing the coupled cluster (CC) equations as the dynamics of excitors in this space, we show that a simple set of rules suffices to evolve a distribution of excitors to sample the CC solution and correctly evaluate the CC energy. These rules ar...
متن کاملContinuum coupled-cluster expansion
One of the major endeavors in modern nuclear physics, is the ongoing quest for an effective nuclear many-body theory, a key element in the attempt to extrapolate existing experimental data to regimes which are not currently accessible in the laboratory. Ideally, one would like to begin with the experimental data available from nucleon-nucleon sNNd scattering experiments [1,2] and determine the ...
متن کاملVibrational coupled cluster theory.
The theory and first implementation of a vibrational coupled cluster (VCC) method for calculations of the vibrational structure of molecules is presented. Different methods for introducing approximate VCC methods are discussed including truncation according to a maximum number of simultaneous mode excitations as well as an interaction space order concept is introduced. The theory is tested on c...
متن کاملQuasi-variational coupled cluster theory.
We extend our previous work on the construction of new approximations of the variational coupled cluster method. By combining several linked pair functional transformations in such a way as to give appropriately balanced infinite-order contributions, in order to approximate (L) well at all orders, we formulate a new quantum chemical method, which we name quasi-variational coupled ...
متن کاملSeniority-based coupled cluster theory.
Doubly occupied configuration interaction (DOCI) with optimized orbitals often accurately describes strong correlations while working in a Hilbert space much smaller than that needed for full configuration interaction. However, the scaling of such calculations remains combinatorial with system size. Pair coupled cluster doubles (pCCD) is very successful in reproducing DOCI energetically, but ca...
