Electron-phonon origins of unconventional resistivity in moderately correlated perovskite oxides
Jennifer Coulter, Fabian B. Kugler, Harrison LaBollita +2
Transition-metal perovskite oxides exhibit moderately correlated metallic phases, several of which exhibit a resistivity scaling up to temperatures far exceeding the regime w…
Correlated electronic structure of the alternating monolayer-bilayer nickelate LaNiO
Harrison LaBollita, Antia S. Botana
The recent discovery of superconductivity under pressure in Ruddlesden-Popper (RP) nickelates has attracted a great deal of attention. Here, using charge-self consistent density-fu…
Low-temperature transport in high-conductivity correlated metals: a density-functional plus dynamical mean-field study of cubic perovskites
Harrison LaBollita, Jeremy Lee-Hand, Fabian B. Kugler +6
While methods based on density-functional perturbation theory have dramatically improved our understanding of electron-phonon contributions to transport in materials, methods for a…
Fermi-Liquid Resistivity: Dynamical Mean-Field Theory Meets Experiment
Fabian B. Kugler, Jeremy Lee-Hand, Harrison LaBollita +6
Direct-current resistivity is a key probe for the physical properties of materials. In metals, Fermi-liquid (FL) theory serves as the basis for understanding transport. A beh…
Electronic layer decoupling driven by density-wave order in LaNiO
Ziqiang Guan, Sophia F. R. TenHuisen, M. Tepie +14
We probe the density-wave transition of the trilayer nickelate LaNiO with polarization-resolved infrared spectroscopy. The low-energy electrodynamics is strongly ani…
Role of correlations in Ruddlesden-Popper bilayer nickelates under compressive strain
Logan Bleys, Nicholas Corkill, Yi-Feng Zhao +4
The recent discovery of superconductivity in thin films of the bilayer Ruddlesden-Popper (RP) nickelate LaNiO (La327) under compressive strain has generated enormous in…
