Modular Construction of Jastrow Factors for the Transcorrelated Method
J. Philip Haupt, Maria-Andreea Filip, Evelin Martine Corvid Christlmaier +3
In this work, we explore the reuse of terms in the Jastrow factor between systems for use in the transcorrelated method, to reduce the number of optimisable parameters for a given…
Deterministic Optimisation of Jastrow Factors
Maria-Andreea Filip, Evelin M. C. Christlmaier, J. Philip Haupt +3
Highly flexible Jastrow factors have found significant use in stochastic electronic structure methods such as variational Monte Carlo (VMC) and diffusion Monte Carlo, as well as in…
Transcorrelated Methods for Multireference Problems
J. Philip Haupt, Evelin M. C. Christlmaier, Pablo López RÃos +3
We apply the transcorrelated method to problems of multireference character. For this, we show that the choice of reference wavefunction during the Jastrow optimisation procedure i…
Transcorrelated Theory with Pseudopotentials
Kristoffer Simula, Evelin Martine Corvid Christlmaier, Maria-Andreea Filip +4
The transcorrelated (TC) method performs a similarity transformation on the electronic Schrödinger equation via Jastrow factorization of the wave function. This has demonstrated s…
Transcorrelated Methods Applied to Second Row Elements
Maria-Andreea Filip, Pablo López RÃos, J. Philip Haupt +3
We explore the applicability of the transcorrelated method to the elements in the second row of the periodic table. We use transcorrelated Hamiltonians in conjunction with full con…
