Double perovskite materials: From Chern bands to unusual Mott insulators
Speaker(s): Arun Paramekanti
Abstract: Double perovskites, a class of oxide materials with 3d and 5d transition metal ions, can realize a wide variety of interesting phases. Here we focus on our recent theoretical work suggesting the appearance of Chern insulators, and possible emergent nematic phases at Chern transitions in such system... read more

Tuning magnetism and Chern bands in spin-orbit coupled double perovskites
Speaker(s): Arun Paramekanti
Abstract: We show that double perovskites with 3d and 5d transition metal ions exhibit spin-orbit coupled magnetic excitations, finding good agreement with neutron scattering experiments in bulk powder samples. Motivated by experimental developments in the field of oxide heterostructures, we also study double... read more

Chiral Mott Insulator of Bosons in a Fully Frustrated Bose Hubbard Model
Speaker(s): Arun Paramekanti
Abstract: Recent experiments have demonstrated that it is possible to create a synthetic magnetic field for neutral atoms in optical lattices using two-photon (Raman) processes. Motivated by exploring the interplay of such artificial magnetic fields and strong correlations for bosons, we have studied the Bose... read more
