Ferromagnetic domains in the large- Hubbard model with a few holes: an FCIQMC study
Sujun Yun, Werner Dobrautz, Hongjun Luo +3
Two-dimensional Hubbard lattices with two or three holes are investigated as a function of in the large- limit. In the so-called Nagaoka limit (one-hole system at infinite $…
Perturbation Calculation of the Uniform Electron Gas with a Transcorrelated Hamiltonian
Hongjun Luo, Ali Alavi
With a transcorrelated Hamiltonian, we perform a many body perturbation (MBPT) calculation on the uniform electron gas in the high density regime. By using a correlation factor opt…
Orders of magnitude reduction in the computational overhead for quantum many-body problems on quantum computers via an exact transcorrelated method
Igor O. Sokolov, Werner Dobrautz, Hongjun Luo +2
Transcorrelated methods provide an efficient way of partially transferring the description of electronic correlations from the ground state wavefunction directly into the underlyin…
Benchmark study of Nagaoka ferromagnetism by spin-adapted full configuration interaction quantum Monte Carlo
Sujun Yun, Werner Dobrautz, Hongjun Luo +1
We investigate Nagaoka ferromagnetism in the two-dimensional Hubbard model with one hole using the spin-adapted ( conserving) full configuration interaction quantum Monte Ca…
Towards efficient and accurate \emph{ab initio} solutions to periodic systems via transcorrelation and coupled cluster theory
Ke Liao, Thomas Schraivogel, Hongjun Luo +2
We propose a streamlined combination scheme of the transcorrelation (TC) and coupled cluster (CC) theory, which not only increases the convergence rate with respect to the basis se…
NECI: N-Electron Configuration Interaction with emphasis on state-of-the-art stochastic methods
Kai Guther, Robert J. Anderson, Nick S. Blunt +22
We present NECI, a state-of-the-art implementation of the Full Configuration Interaction Quantum Monte Carlo algorithm, a method based on a stochastic application of the Hamiltonia…
