Explore the effects of electron-doping in the Ba2Na1−xCaxOsO6 Mott insulator with strong spin-orbit coupling in this 38-minute conference talk from the Workshop on "Spin-Orbit Entangled Quantum Magnetism" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the evolution of magnetic and broken local point symmetry (BLPS) phases in Ba2Na1−xCaxOsO6 across the full doping range, examined through nuclear magnetic resonance and muon spin spectroscopy. Discover the persistence of the BLPS phase, indicating preserved multipolar character, and learn about anomalous peaks in relaxation rates attributed to electric field gradient fluctuations. Gain insights into the formation of spin-orbital bipolarons as a crucial element in Dirac-Mott insulator physics, supported by a combination of ab initio calculations and experimental measurements.
