Description:
ebcc 1.5.0
ebcc: Coupled cluster calculations on electron-boson systems
The ebcc package implements various coupled cluster (CC) models for both purely electronic and coupled electron-boson models, with a focus on generality and model extensibility.
For a summary of the implemented models, see the FEATURES.md file.
Installation
From PyPI:
pip install ebcc
From source:
git clone https://github.com/BoothGroup/ebcc
pip install .
Usage
The implemented models are built upon the mean-field objects of pyscf:
from pyscf import gto, scf
from ebcc import EBCC
mol = gto.M(atom="H 0 0 0; H 0 0 1", basis="cc-pvdz")
mf = scf.RHF(mol)
mf.kernel()
ccsd = EBCC(mf, ansatz="CCSD")
ccsd.kernel()
Code generation
The models implemented are generated algorithmically from expressions over second quantized operators. The scripts for generating these models are found in the codegen directory on the bootstrap branch.
User-inputted models should operate seamlessly with the solvers by adding files under ebcc/codegen, so long as they satisfy the interface.
