From E_{2g} to other modes : Effects of pressure on electron-phonon interaction in MgB_2
Prabhakar P. Singh
We study the effects of pressure on the electron-phonon interaction in MgB_2 using density-functional-based methods. Our results show that the superconductivity in MgB_2 vanishes b…
Prediction of Superconductivity at ~ 30 K in Compressed Body-Centered Cubic Yttrium
Prabhakar P. Singh
Using ab initio methods, we have studied the electron-phonon interaction in compressed, body-centered cubic (bcc) yttrium, which is predicted to be stable at 280 GPa [Melsen et al,…
Electronic Structure and Electron-Phonon Interaction in Hexagonal Yttrium
Prabhakar P. Singh
To understand the pressure-induced changes in the electronic structure and the electron-phonon interaction in yttrium, we have studied hexagonal close-packed (hcp) yttrium, stable…
Theoretical Study of Electronic Structure and Superconductivity in Nb_(1-x)B_2 Alloys
P. Jiji Thomas Joseph, Prabhakar P. Singh
Using the Korringa-Kohn-Rostoker coherent-potential approximation in the atomic-sphere approximation (KKR-ASA CPA) we have studied the changes in the electronic structure and the s…
Carbon Doping in MgB_2 : Role of Boron and Carbon p_x(y) Bands
Prabhakar P. Singh
We have studied the changes in the electronic structure and the superconducting transition temperature T_c of Mg(B_{1-x}C_{x})_{2} alloys as a function of x with 0\leq x\leq 0.3. O…
Theoretical Study of Electron-Phonon Interaction in ZrB2 and TaB2
Prabhakar P. Singh
Using full-potential, density-functional-based methods we have studied electron-phonon interaction in ZrB2 and TaB2 in P6/mmm crystal structure. Our results for phonon density of s…
