Integrating dynamical mean-field theory and diagrammatic Monte Carlo
Johan Carlström
Dynamical mean-field theory (DMFT) is one of the most widely used theoretical methods for electronic structure calculations, providing self-consistent solutions even in low-tempera…

Spectral shift technique for strongly correlated lattice fermions
Johan Carlström
We present a development of strong-coupling diagrammatic techniques which relies on integrating out mean-field-like paths prior to conducting the expansion. This makes it possible…

Diagrammatic Monte Carlo procedure for the spin-charge transformed Hubbard model
Johan Carlström
Using a dual representation of lattice fermion models that is based on spin-charge transformation and fermionisation of the original description, I derive an algorithm for diagramm…
