The Fermi surface of NaCoO
Peihong Zhang, Weidong Luo, Marvin L. Cohen +1
Doping evolution of the Fermi surface topology of NaCoO is studied systematically. Both local density approximation (LDA) and local spin density approximation (LSDA) predic…
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…
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…
Scaling Considerations in Ground State Quantum Computation
Ari Mizel, M. W. Mitchell, Marvin L. Cohen
We study design challenges associated with realizing a ground state quantum computer. In such a computer, the energy gap between the ground state and first excited state must be su…
