Second Dome of Superconductivity in YBaCuO at High Pressure
Johannes Nokelainen, Matthew E. Matzelle, Christopher Lane +6
Evidence is growing that a second dome of high- superconductivity can be accessed in the cuprates by increasing the doping beyond the first dome. Here we use \emph{ab…
Critical role of magnetic moments on lattice dynamics in YBaCuO
Jinliang Ning, Christopher Lane, Yubo Zhang +6
The role of lattice dynamics in unconventional high-temperature superconductivity is still vigorously debated. Theoretical insights into this problem have long been prevented by th…
Sensitivity of the electronic and magnetic structures of cuprate superconductors to density functional approximations
Kanun Pokharel, Christopher Lane, James W. Furness +7
We discuss the crystal, electronic, and magnetic structures of (LSCO) for and employing 13 density functional approximations, repr…
Ab initio description of the BiSrCaCuO electronic structure
J. Nokelainen, C. Lane, R. S. Markiewicz +6
Bi-based cuprate superconductors are important materials for both fundamental research and applications. As in other cuprates, the superconducting phase in the Bi compounds lies cl…
Landscape of competing stripe and magnetic phases in cuprates
Yubo Zhang, Christopher Lane, James W. Furness +4
Realistic modeling of competing phases in complex quantum materials has proven extremely challenging. For example, much of the existing density-functional-theory-based first-princi…
Resolving unoccupied electronic states with laser ARPES in bismuth-based cuprate superconductors
Tristan L Miller, Minna Ärrälä, Christopher L. Smallwood +11
Angle-resolved photoemission spectroscopy (ARPES) is typically used to study only the occupied electronic band structure of a material. Here we use laser-based ARPES to observe a f…
High-temperature cuprate superconductors studied by x-ray Compton scattering and positron annihilation spectroscopies
Bernardo Barbiellini
The bulk Fermi surface in an overdoped () single crystal of LaSrCuO has been observed by using x-ray Compton scattering. This momentum density techniqu…
Effects of excess or deficiency of oxygen content on the electronic structure of high- cuprates
T. Jarlborg, A. Bianconi, B. Barbiellini +2
Band structure calculations are presented for large supercells of BaCuO (BCO) with O-vacancies in planar or apic al positions, and of superoxygenated LaCuO (LCO) wi…
Different doping from apical and planar oxygen vacancies in BaCuO and LaCuO
T. Jarlborg, B. Barbiellini, R. S. Markiewicz +1
First principles band-structure calculations for large supercells of BaCuO and LaCuO with different distributions and concentrations of oxygen vacancies…
Uniaxial "nematic-like" electronic structure and Fermi surface of untwinned CaFe2As2
Qiang Wang, Zhe Sun, Eli Rotenberg +8
Obtaining the electronic structure of the newly discovered iron-based superconductors is the key to understanding the mechanism of their high-temperature superconductivity. We used…
Hole depletion and localization due to disorder in insulating PrBa2Cu3O7-d: a Compton scattering study
Abhay Shukla, Bernardo Barbiellini, Andreas Erb +4
The (mostly) insulating behaviour of PrBa2Cu3O7-d is still unexplained and even more interesting since the occasional appearance of superconductivity in this material. Since YBa2Cu…
Momentum density of high Tc Copper Oxydes
B. Barbiellini, P. M. Platzman
We discuss the work aimed at studying the momentum density of high Tc superconducting oxides using Compton profile and positron annihilation spectroscopies.
