The magnetic nature of a quasi-one-dimensional compound, BaVSe 3, has been
investigated with positive muon spin rotation and relaxation (μ+ SR) measurements at …

The magnetic properties of Zintl phase barium vanadium selenide (BaVSe3) were
investigated experimentally and theoretically. BaVSe3, synthesized through a solid-state …

Abstract Quasi-one-dimensional (Q1D) materials possess extraordinary magnetic and
transport characteristics, which render them of critical importance. In this study, we present …

The dynamical mean-field theory (DMFT) has become a standard technique for the study of
strongly correlated models and materials overcoming some of the limitations of density …

The combination of the local‐density approximation (LDA) with the rotationally invariant
slave‐boson theory (RISB) is used to investigate the realistic correlated electronic structure …

We present an implementation of the rotationally invariant slave boson technique as an
impurity solver for density functional theory plus dynamical mean field theory (DFT+ DMFT) …

BaVS 3 presents a metal-to-insulator (MI) transition at ambient pressure due to the
stabilization of a 2k F commensurate charge density wave (CDW) Peierls ground state built …

The subject of the work at hand is the combination of density functional theory, mainly in its
local density approximation (LDA), with methods that describe many-particle effects …

We develop a versatile first-principles many-body scheme for multiorbital lattice
susceptibilities including full frequency-dependent local vertex effects and investigate the …
