Affordable Five-Orbital Dynamical Mean-Field Theory for Layered Iridates and Rhodates
Léo Gaspard, Cyril Martins
Full -manifold DMFT with numerically exact solvers has remained computationally prohibitive for spin-orbit materials due their scaling and severe sign problem, forcing the commu…
Spin-polaron fingerprints in the optical conductivity of iridates
Francesco Cassol, Léo Gaspard, Cyril Martins +2
As a consequence of their spin-orbit entangled ground state, many iridate materials display a peculiar double peak structure in optical transport quantities, such as absor…
The rich phase diagram of the prototypical iridate BaIrO: Effective low-energy models and metal-insulator transition
Francesco Cassol, Léo Gaspard, Michele Casula +2
In the quest of new exotic phases of matter due to the interplay of various interactions, iridates hosting a spin-orbit entangled ground state have been in t…
Absence of a direct metal to Mott insulator transition for disordered interacting fermions on the Cayley tree
Ankita Chakrabarti, Nicolas Laflorencie, Bertrand Georgeot +2
Interacting fermions in the presence of disorder pose one of the most challenging problems in condensed matter physics, primarily due to the absence of accurate numerical tools. Ou…
