DOI: 10.1002/adfm.202306964
Abstract: Electrical signatures for quantum magnetic phases of α‐RuCl3 sensed by an adjacent graphene field‐effect transistor (FET) are reported. The gate‐voltage dependence of the graphene FET reveals p‐type doping beneath α‐RuCl3 caused by the charge transfer… 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.
