Alkali-doped fullerides show a wide range of electronic phases in function of alkali atoms and the degree of doping. Although the presence of strong electron correlations is well established, recent investigations also give evidence for dynamical Jahn–Teller instability in the insulating and the metallic trivalent fullerides. In this work, to reveal the interplay of these interactions in fullerides with even electrons, we address the electronic phase of tetravalent fulleride with accurate many…

Electron Transport in Configurational Model of Ferromagnetic Fulleride with Triple Orbital Degeneracy
Abstract Phenomenon of ferromagnetic ordering was for a long time associated exclusively with transition metal and rare-earth compounds. Nowadays this view is challenged by growing evidence that in
Tuning the electronic states and superconductivity in alkali fulleride films
The successful preparation of superconducting alkali fulleride (AxC60, A = K, Rb, Cs) films using state-of-the-art molecular beam epitaxy overcomes the disadvantages of the air-sensitivity and phase
Direct Observation of Full-Gap Superconductivity and Pseudogap in Two-Dimensional Fullerides.
Cryogenic scanning tunneling microscopy is employed to show that trilayer K_{3}C_{60} displays fully gapped strong coupling s-wave superconductivity, accompanied by a pseudogap above T_{c}∼22  K and within vortices, which indicates that alkali fullerides are predominantly phonon-mediated superconductors, although the electronic correlations also come into play.
Manifestation of vibronic dynamics in infrared spectra of Mott insulating fullerides
The fine structure and temperature evolution of infrared spectra have been intensively used to probe the nature of Jahn-Teller dynamics in correlated materials. At the same time, theoretical
Nonempirical Calculation of Superconducting Transition Temperatures in Light‐Element Superconductors
This study obtains a unified view of the high-Tc superconductivity and the Mott-Hubbard transition in the fullerides and demonstrates that the combination of density functional theory and dynamical mean field theory with the ab initio downfolding scheme for electron-phonon coupled systems works successfully.

Rb0.5Cs2.5C60 is a member of the family of face-centred-cubic (fcc)–structured alkali fullerides, A3C60 (A = alkali metal) with a highly expanded lattice size. At ambient temperature and pressure, it

Dynamical Jahn-Teller instability in metallic fullerides
Dynamical Jahn-Teller effect has escaped so far direct observation in metallic systems. It is particularly believed to be quenched also in correlated conductors with orbitally degenerate sites such

Alkali-doped fullerides have attracted strong interest since their production became possible about fifteen years ago. This book presents work which may solve intriguing problems arising from a
Exotic s-wave superconductivity in alkali-doped fullerides.
Recent ab initio calculations confirm that the alkali-doped fullerides are a new type of unconventional superconductors, where the unusual synergy between the phonons and Coulomb interactions drives the high-Tc superconductivity.
Jahn–Teller orbital glass state in the expanded fcc Cs3C60 fulleride
The most expanded fcc-structured alkali fulleride, Cs3C60, is a Mott insulator at ambient pressure because of the weak overlap between the frontier t1u molecular orbitals of the C603− anions. It has

The Jahn-Teller metal is identified as a fluctuating microscopically heterogeneous coexistence of both localized and itinerant electrons that connects the insulating and superconducting states of fullerides.
The Mott–Hubbard insulating state and orbital degeneracy in the superconducting C603− fulleride family
This work describes the first example of a cubic C603− system with degenerate orbitals that adopts the Mott–Hubbard insulating localized electron ground state and demonstrates that it is the orbital degeneracy that allows the superconducting cubic A3C60 fullerides to remain metallic while provoking electron localization in systems with lower symmetry.
Dynamic Jahn-Teller effect in the parent insulating state of the molecular superconductor Cs₃C₆₀.
Evidence is presented for the dynamic Jahn-Teller effect as the source of the dramatic change in electronic structure occurring during the transition from the metallic to the localized state and the temperature dependence of the spectra in the insulating phase can be explained by the gradual transformation from two temperature-dependent solid-state conformers to a single one.

The Disorder-Free Non-BCS Superconductor Cs3C60 Emerges from an Antiferromagnetic Insulator Parent State
In Cs3C60, where the molecular valences are precisely assigned, the superconducting state at 38 kelvin emerges directly from a localized electron antiferromagnetic insulating state with the application of pressure, with a dependence of the transition temperature on pressure-induced changes of anion packing density that is not explicable by Bardeen-Cooper-Schrieffer (BCS) theory.
