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…

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…

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.
