Nanoscale orbital excitations and the infrared spectrum of a molecular Mott insulator: A15-Cs${}_3$C${}_{60}$

S. Shahab Naghavi, Michele Fabrizio, Tao Qin +1

The quantum physics of ions and electrons behind low-energy spectra of strongly correlated {\it molecular} conductors, superconductors and Mott insulators is poorly known, yet fasc…
