Multi-band D-TRILEX approach to materials with strong electronic correlations

چکیده
We present the multi-band dual triply irreducible local expansion (D-TRILEX) approach to interacting electronic systems and discuss its numerical implementation. This method is designed for a self-consistent description of multi-orbital that can also have several atoms in unit cell. The current implementation D-TRILEX able account frequency- channel-dependent long-ranged interactions. show our accurate when applied small such as Hubbard-Kanamori dimer. Calculations extended Hubbard, two-orbital Hubbard-Kanamori, bilayer Hubbard models are discussed.

Multi-materials with strong interface: Variational modelings
We introduce a simplified model for a multi-material made up of two elastic bodies connected by a strong thin material layer whose stiffness grows as 1 . The model is obtained by identifying the Γ-limit of the stored strain energy functional of the physical problem when the thickness of the intermediate layer tends to zero. The intermediate layer behaves as a stiffening elastic membrane. Furthe...

متن کاملStrong Electronic Correlations and Low Energy Scales
One of the many fascinating aspects of strongly correlated electron systems is the appearance of low energy scales: interesting physical phenomena are observed on an energy (and temperature) scale much lower than e.g. local Coulomb repulsion, hybridization, etc. Well known examples are heavy fermion compounds and systems in the vicinity of a metal-insulator transition. These phenomena can be de...
متن کاملStrong electronic correlations in LixZnPc organic metals.
Nuclear magnetic resonance, electron paramagnetic resonance and magnetization measurements show that bulk LixZnPc are strongly correlated one-dimensional metals. The temperature dependence of the nuclear spin-lattice relaxation rate 1/T_{1} and of the static uniform susceptibility chi_{S} on approaching room temperature are characteristic of a Fermi liquid. Moreover, while for x approximately 2...
متن کاملMulti-criteria approach to project portfolio selection considering structural hardness and correlations between projects
Project portfolio selection is very important subject of decision-makers in project-based organizations. The best assignment of resources to the most appropriate projects is necessary as financing projects with low benefit is just waste of organization's resources. However, existing project selection models pay not much attention the structure and special features of projects as a selection cri...
