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…
