Theory of unconventional metamagnetic electron states in orbital band systems

Theory of unconventional metamagnetic electron states in orbital band systems

We extend the study of the Fermi surface instability of the Pomeranchuk type into systems with orbital band structures, which are common features in transition metal oxides. Band hybridization significantly shifts the spectral weight of the Landau interactions from the conventional s-wave channel to unconventional non-s-wave channels, which results in anisotropic nematic Fermi surface distortio...

Quasiparticle interference in the unconventional metamagnetic compound Sr3Ru2O7

Quasiparticle interference QPI in spectroscopic imaging scanning tunneling microscopy provides a powerful method to detect orbital band structures and orbital ordering patterns in transition-metal oxides. We use the T-matrix formalism to calculate the QPI spectra for the unconventional metamagnetic system of Sr3Ru2O7 with a t2g-orbital band structure. A detailed tight-binding model is construct...

Density Functional Theory (DFT), Natural Band Orbital and Energy Studies of N-(2-Fluorophenyl)-2,6-dimethyl-1,3-dioxan-4-amine

In this paper,N-(2-Fluorophenyl)-2,6-dimethyl-1,3-dioxan-4-amine (C12H16FNO2) optimized geometries and frequencies of the stationary point and energies in the ground state using DFT (B3LYP) methods with 6-311Gbasis set. The calculated HOMO and LUMO energies also confirmed that the charge transfer occurred within the molecule. Bond length and bond angles values forC12H16FNO2 were calculated by u...

Band-Gap Tuning Of Electron Beam Evaporated Cds Thin Films

The effect of evaporation rate on structural, morphological and optical properties of electron beam evaporated CdS thin films have been investigated. CdS thin film deposited by electron beam evaporation method in 12nm/min and 60nm/min evaporation rates on glass substrates. X-ray diffraction, scanning electron microscopy, UV-Vis-NIR spectroscopy and Atomic Force Microscopy were used to character...
