Phonon anomalies in pure and underdoped R{1-x}K{x}Fe{2}As{2} (R = Ba, Sr) investigated by Raman light scattering
M. Rahlenbeck, G. L. Sun, D. L. Sun +3
We present a detailed temperature dependent Raman light scattering study of optical phonons in Ba{1-x}K{x}Fe{2}As{2} (x ~ 0.28, superconducting Tc ~ 29 K), Sr{1-x}K{x}Fe{2}As{2} (x…
Dominant parameters for the critical tunneling current in bilayer exciton condensates
L. Tiemann, Y. Yoon, W. Dietsche +2
We will discuss the relevant conditions to observe a critical tunneling current [New J. Phys. 10, 045018 (2008)] in electron double-layer systems at a total filling factor of 1 and…
Superconductivity in Fe and As based compounds: a bridge between MgB2 and cuprates
A. Bussmann-Holder, A. Simon, H. Keller +1
By interpreting various experimental data for the new high temperature FeAs type superconductors in terms of lattice mediated multi gap superconductivity, it is shown that these sy…
Identifying the pairing mechanism in Fe-As based superconductors: gaps and isotope effects
A. Bussmann-Holder, A. Simon, H. Keller +1
The temperature dependencies of the coupled superconducting gaps, observed in Fe-As based superconducting compounds is calculated and a universal temperature scaling observed which…
Electronic structure of Pr_{2-x}Ce_xCuO_4 studied via ARPES and LDA+DMFT+Σ_k
I. A. Nekrasov, N. S. Pavlov, E. Z. Kuchinskii +10
The electron-doped Pr(2-x)Ce(x)CuO(4) (PCCO) compound in the pseudogap regime (x~0.15) was investigated using angle-resolved photoemission spectroscopy (ARPES) and the generalized…
Magnetically Hidden Order of Kramers Doublets in Systems: SrVO
George Jackeli, Giniyat Khaliullin
We formulate and study an effective Hamiltonian for low-energy Kramers doublets of -ions on a square lattice. We find that the system exhibits a magnetically hidden order in w…
