Structure and optical properties of alpha- and gamma-cerium sesquisulfide
Rene Windiks, Erich Wimmer, Leonid Pourovskii +2
Structural and electronic properties of the alpha- and gamma-phases of cerium sesquisulfide, Ce2S3, are examined by first-principles calculations using the GGA+U extension of densi…
Dynamical mean-field theory using Wannier functions: a flexible route to electronic structure calculations of strongly correlated materials
F. Lechermann, A. Georges, A. Poteryaev +4
A versatile method for combining density functional theory (DFT) in the local density approximation (LDA) with dynamical mean-field theory (DMFT) is presented. Starting from a gene…
Breakup of the Fermi surface near the Mott transition in low-dimensional systems
C. Berthod, T. Giamarchi, S. Biermann +1
We investigate the Mott transition in weakly-coupled one-dimensional (1d) fermionic chains. Using a generalization of Dynamic Mean Field Theory, we show that the Mott gap is suppre…
