Importance of effective Coulomb interactions for in cuprates
Jakša Vučičević, Upendra Kumar, Chia-Nan Yeh +2
Cuprate superconductors exhibit the highest observed superconducting at atmospheric pressure. However, the magnitude of varies significantly between different cuprates.…
Hubbard vs. Emery model: spectra, transport and relevance for cuprates
Jakša Vučičević, Rok Žitko
Understanding the transport properties of cuprate superconductors is one of the central challenges in the physics of strongly correlated electrons. The most common approach is to d…
Open Quantum Cluster Embedding Theory
Petar Brinić, Hugo U. R. Strand, Jakša Vučičević
The simulation of strongly correlated electron systems remains a formidable challenge. Certain experimentally relevant dynamical response functions are especially difficult to calc…
Exact downfolding and its perturbative approximation
Jonas B. Profe, Jakša Vučičević, P. Peter Stavropoulos +3
Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…
Conductivity of lattice bosons at high temperatures
Ivana Vasić, Jakša Vučičević
Quantum simulations are quickly becoming an indispensable tool for studying particle transport in correlated lattice models. One of the central topics in the study of transport is…
