DOI: 10.1016/j.jallcom.2020.155351
Abstract: Abstract Iridium-based double perovskite oxides (DPO) provide a rich variety of multifunctional properties and technological applications due to their entangled spin-orbit coupling (SOC) state. Here, we theoretically investigated the electronic and magnetic properties of newly… read more here.

DOI: 10.1063/1.5126616
Abstract: Herein, phonon engineering is applied to a metal. Suppressed phonon branches are expected to enhance electron–phonon interactions in metals. Independent resistance and magnetization measurements have confirmed the Mott transition, which has never been observed in… read more here.

DOI: 10.1103/physrevb.100.075111
Abstract: Unveiling the physics that governs the intertwining between the nanoscale self-organization and the dynamics of insulator-to-metal transitions (\textit{IMT}) is key for controlling on demand the ultrafast switching in strongly correlated materials and nano-devices. A paradigmatic… read more here.

DOI: 10.1103/physrevb.97.115113
Abstract: We study a simple model of photovoltaic energy harvesting across a Mott insulating gap consisting of a correlated layer connected to two metallic leads held at different chemical potentials. Upon driving the layer with a… read more here.

DOI: 10.1103/physrevx.9.011035
Abstract: V2O3 famously features all four combinations of paramagnetic vs antiferromagnetic, and metallic vs insulating states of matter in response to %-level doping, pressure in the GPa range, and temperature below 300 K. Using time-of-flight neutron… read more here.
