Semilocal exchange hole with an application to range-separation density functional
Jianmin Tao, Ireneusz W. Bulik, Gustavo E. Scuseria
Exchange-correlation hole is a central concept in density functional theory. It not only provides justification for an exchange-correlation energy functional, but also serves as a…
Combinations of coupled cluster, density functionals, and the random phase approximation for describing static and dynamic correlation, and van der Waals interactions
Alejandro J. Garza, Ireneusz W. Bulik, Ana G. Sousa Alencar +3
Contrary to standard coupled cluster doubles (CCD) and Brueckner doubles (BD), singlet-paired analogues of CCD and BD (denoted here as CCD0 and BD0) do not break down when static c…
Can single-reference coupled cluster theory describe static correlation?
Ireneusz W. Bulik, Thomas M. Henderson, Gustavo E. Scuseria
While restricted single-reference coupled cluster theory truncated to singles and doubles (CCSD) provides very accurate results for weakly correlated systems, it usually fails in t…
Pair extended coupled cluster doubles
Thomas M. Henderson, Ireneusz W. Bulik, Gustavo E. Scuseria
The accurate and efficient description of strongly correlated systems remains an important challenge for computational methods. Doubly occupied configuration interaction (DOCI), in…
Seniority-based coupled cluster theory
Thomas M. Henderson, Ireneusz W. Bulik, Tamar Stein +1
Doubly occupied configuration interaction (DOCI) with optimized orbitals often accurately describes strong correlations while working in a Hilbert space much smaller than that need…
Electron correlation in solids via density embedding theory
Ireneusz W. Bulik, Weibing Chen, Gustavo E. Scuseria
Density matrix embedding theory (Phys. Rev. Lett. 109, 186404 (2012)) and density embedding theory ((Phys. Rev. B 89, 035140 (2014)) have recently been introduced for model lattice…
