Mott transitions and Novel Orders in Multi-Orbital Models: The Relevance of Structural "Double Exchange"

Mukul S. Laad, S. Koley, A. Taraphder

In real transition-metal oxides, the so-called GdFeO3 octahedral tilt is long known to be a relevant control parameter influencing the range of orbital and magnetic ordered states…

Emergent Quantum Coherence from Instabilities of a Perturbed Fractionalized Spin Liquid

Swagata Acharya, M. S. Laad, A. Taraphder

Effects of perturbations on topologically ordered (TO) states with fractionalized excitations is very intriguing. While small perturbations are not expected to affect a robust TO,…
