Multiplet structure of chromium(III) dopants in wide band gap materials

Ilya Popov, Petros-Panagis Filippatos, Shayantan Chaudhuri +3

Transition metal doping is commonly used for altering the properties of solid-state materials to suit applications in science and technology. Partially filled -shells of transit…

Efficient magnetic superstructure optimization with

Evgeny A. Plekhanov, Andrei L. Tchougréeff

Simulating the incommensurate spin density waves (ISDW) states is not a simple task within the standard \emph{ab-initio} methods. Moreover, in the context of new material discovery…

Calculating Bardeen-Cooper-Schrieffer and Magnetic Superstructure Electronic States with

Evgeny Plekhanov, Andrei Tchougréeff, Richard Dronskowski

We propose the (Theta-Phi) package which addresses two of the most important extensions of the essentially single-particle mean-field paradigm of the computational solid state…

c-a-ca Mean Field RVB Model of CuNCN Physics. Structure Manifestations of the RVB Transitions

A. L. Tchougréeff, R. Dronskowski

We propose a new form of the frustrated Heisenberg antiferromagnetic Hamiltonian with spatially anisotropic exchange parameters Jc, Ja, and Jac extended along the c, a, and a +/- c…

On the Properties of the Longitudinal RVB State in the Anisotropic Triangular Lattice. Mean-Field RVB Analytical Results

A. L. Tchougréeff, R. Dronskowski

The spin-1/2 Heisenberg model on an anisotropic triangular lattice is considered in the mean-field RVB approximation. The analytical estimates for the critical temperatures of the…
