We report on theoretical calculations of the optical conductivity of Ba [Fe(1-x)Co(x)]2 As2, as obtained from density functional theory within the full potential LAPW method. A thorough comparison with experiment shows that we are able to reproduce most of the observed experimental features, in particular a magnetic peak located at about 0.2 eV which we ascribe to antiferromagnetic ordered magnetic stripes. We also predict a large in-plane anisotropy of this feature, which agrees very well with…

Carrier dynamics of Ba(Fe 1- x Co x ) 2 As 2 as a function of doping
In this thesis a systematic light scattering study of the newly discovered iron-based superconductor Ba(Fe1-xCox)2As2 is presented. The main focus is placed on the study of electronic properties in a
Distribution of Optical Spectral Weight in Detwinned Ba(Fe1−xCox)2As2
We analyze our recent optical investigation on detwinned Ba(Fe1−xCox)2As2 materials in the underdoped regime from the perspective of the spectral weight (SW) distribution. We identify its evolution
Anisotropic in-plane optical conductivity in detwinned Ba(Fe1?xCox)2As2
We study the anisotropic in-plane optical conductivity of detwinned Ba(Fe1 xCox)2As2 single crystals for x = 0, 2.5 and 4.5% in a broad energy range (3meV-5eV) across their structural and magnetic
Origin of the Resistive Anisotropy in the Electronic Nematic Phase of BaFe(2)As(2) Revealed by Optical Spectroscopy.
The infrared response reveals that the dc transport anisotropy in the orthorhombic AFM state is determined by the interplay between the Drude spectral weight and the scattering rate, but that the dominant effect is clearly associated with the metallic spectral weight.
Nematic Fluctuations, Fermiology and the Pairing Potential in Iron-Based Superconductors
The thesis comprises a systematic study on the doping, temperature and momentum dependent electron dynamics in iron-based superconductors using inelastic light scattering. The observation of
Monotonic Doping-Dependence in the Anisotropy of the Drude Weight and Scattering Rate of Detwinned Ba(Fe1−xCox)2As2 Established from the Optical Conductivity
We investigate the anisotropic metallic response in the optical conductivity of fully detwinned Ba(Fe1−x Cox)2As2 in their underdoped regime. We estimate the Drude weight and the scattering rates of
Dichroism in the Parent Ferropnictide BaFe2As2 Across the Nematic Phase Transition
We investigate the anisotropy of the optical response (i.e., dichroism) in the representative ‘parent’ ferropnictide BaFe2As2. The dichroism is achieved through measurements of the optical
Unprecedented anisotropic metallic state in undoped iron arsenide BaFe2As2 revealed by optical spectroscopy
Detailed analysis of the optical spectra reveals an unprecedented electronic state in the ordered phase of iron arsenides, arising from an anisotropic energy gap opening below and slightly above the onset of the order.
In-plane electronic anisotropy of underdoped '122' Fe-arsenide superconductors revealed by measurements of detwinned single crystals
The parent phases of the Fe-arsenide superconductors harbor an antiferromagnetic ground state. Significantly, the Neel transition is either preceded or accompanied by a structural transition that
Cooper pairing and fluctuations in Fe-based superconductors
Unconventional superconductivity generally occurs in proximity to magnetic phases. Raman spectroscopy affords a window into most of the related excitations including pairing interactions. Thus, the


Correspondence on "Electronic correlations in the iron pnictides"
I point out that the observed discrepancy between the measured and calculated Drude weights in LaFePO may be caused not only by mass renormalization, but also by a DFT inaccuracy in determining the
Response to I. I. Mazin's correspondence on
We discuss the discrepancy between the measured optical Drude weight and band structure calculations in LaFePO and other iron-based superconductors. This discrepancy is mostly due to mass
Planewaves, Pseudopotentials, and the LAPW Method
With its extreme accuracy and reasonable computational efficiency, the linearized augmented planewave (LAPW) method has emerged as the standard by which density functional calculations for transition
