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…
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…
Microscopic mechanisms of flexoelectricity in oxide membranes
Harikrishnan KP, Varun Harbola, Jaehong Choi +9
Modern electromechanical actuators and sensors rely on the piezoelectric effect that linearly couples strain and electric polarization. However, this effect is restricted to materi…
