Interaction expansion inchworm Monte Carlo solver for lattice and impurity models
Jia Li, Yang Yu, Emanuel Gull +1
Multi-orbital quantum impurity models with general interaction and hybridization terms appear in a wide range of applications including embedding, quantum transport, and nanoscienc…
Efficient ab initio many-body calculations based on sparse modeling of Matsubara Green's function
Hiroshi Shinaoka, Naoya Chikano, Emanuel Gull +6
This lecture note reviews recently proposed sparse-modeling approaches for efficient ab initio many-body calculations based on the data compression of Green's functions. The sparse…
Diagrammatic Monte Carlo Method for Impurity Models with General Interactions and Hybridizations
Jia Li, Markus Wallerberger, Emanuel Gull
We present a diagrammatic Monte Carlo method for quantum impurity problems with general interactions and general hybridization functions. Our method uses a recursive determinant sc…
Direct comparison of many-body methods for realistic electronic Hamiltonians
Kiel T. Williams, Yuan Yao, Jia Li +22
A large collaboration carefully benchmarks 20 first principles many-body electronic structure methods on a test set of 7 transition metal atoms, and their ions and monoxides. Good…
Towards the solution of the many-electron problem in real materials: equation of state of the hydrogen chain with state-of-the-art many-body methods
Mario Motta, David M. Ceperley, Garnet Kin-Lic Chan +18
We present numerical results for the equation of state of an infinite chain of hydrogen atoms. A variety of modern many-body methods are employed, with exhaustive cross-checks and…
