Prediction of superconducting properties of CaB2 using anisotropic Eliashberg theory

Hyoung Joon Choi, Steven G. Louie, Marvin L. Cohen

Superconducting properties of hypothetical simple hexagonal CaB2 are studied using the fully anisotropic Eliashberg formalism based on electronic and phononic structures and electr…

Electron-phonon interaction alone does not explain the photoemission kink in cuprate superconductors

Feliciano Giustino, Marvin L. Cohen, Steven G. Louie

Despite over two decades of intense research efforts, the origin of high-temperature superconductivity in the copper oxides remains elusive. Angle-resolved photoemission experiment…

Hole doping MgB without chemical substitution

Peihong Zhang, Susumu Saito, Steven G. Louie +1

Structures for realizing hole-doped MgB without appealing to chemical substitutions are proposed. These structures which consist of alternating MgB and graphene layers have…

Doping effects on the electronic and structural properties of CoO2: An LSDA+U study

Peihong Zhang, Weidong Luo, Vincent H. Crespi +2

A systematic LSDA+U study of doping effects on the electronic and structural properties of single layer CoO2 is presented. Undoped CoO2 is a charge transfer insulator within LSDA+U…

Reply to "Comment on `First-principles calculation of the superconducting transition in MgB2 within the anisotropic Eliashberg formalism'"

Hyoung Joon Choi, David Roundy, Hong Sun +2

The recent preprint by Mazin et al. [cond-mat/0212417] contains many inappropriate evaluations and/or criticisms on our published work [Phys. Rev. B 66, 020513 (2002) and Nature 41…

Superconducting energy gaps, low temperature specific heat, and quasiparticle spectra of MgB2

Hyoung Joon Choi, David Roundy, Hong Sun +2

We report first-principles calculations of the k- and T-dependent superconducting gap Delta(k,T) in MgB2 and its manifestation in various measured quantities. Because the Fermi sur…
