Single- and two-particle finite size effects in interacting lattice systems
Sergei Iskakov, Hanna Terletska, Emanuel Gull
Simulations of extended quantum systems are typically performed by extrapolating results of a sequence of finite-system-size simulations to the thermodynamic limit. In the quantum…
Ab initio Approaches to High Entropy Alloys: A Comparison of CPA, SQS, and Supercell Methods
Mariia Karabin, Wasim Mondal, Andreas Ostlin +7
We present a comparative study of different modeling approaches to the electronic properties of the $\textrm{Hf}_{0.05}\textrm{Nb}_{0.05}\textrm{Ta}_{0.8}\textrm{Ti}_{0.05}\textrm{…
One- and two-particle properties of the weakly interacting two-dimensional Hubbard model in proximity to the van Hove singularity
B. D. E. McNiven, Hanna Terletska, G. T. Andrews +1
We study the weak-coupling limit of the Hubbard model on a two-dimensional square lattice using a direct perturbative approach. Aided by symbolic computational tools…
