Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

This review aims to summarize more than 100 years of research on spinel compounds,
mainly focusing on the progress in understanding their magnetic, electronic, and polar …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

First principles density functional calculations of the electronic and magnetic properties of
the layered oxide NaCo 2 O 4 have been performed using the general potential linearized …

The heavy fermion physics is dictated by subtle competing exchange interactions, posing a
challenge to their understanding. One-dimensional (1D) Kondo lattice model has attracted …

The ground-state properties of the spin-1 antiferromagnetic Heisenberg model on the corner-
sharing tetrahedra, the pyrochlore lattice, are investigated. By breaking up each spin into a …

Transport and specific heat measurements on hydrothermally grown single crystals reveal
the formation of a heavy-mass Fermi liquid in the LiV 2 O 4 spinel, below a coherence …

The spinel crystal system, AB 2 O 4, has been fertile ground in studying the effects of
magnetic and orbital frustration. The experimental findings, with primary focus on neutron …

Here, we experimentally study the origin of d-electron heavy fermion (HF) behavior in iron-
based superconductors (FeSCs) A Fe 2 As 2 (A= K, Rb, Cs). Nuclear magnetic resonance …

We study the competition between the Kondo effect and frustrating exchange interactions in
a Kondo-lattice model within a large-N dynamical mean-field theory. We find a T= 0 phase …
