Three-particle mechanism for unconventional superconductivity with potential applications in moiré materials
A novel electronic mechanism for superconductivity is introduced, wherein pairing between two conduction electrons is mediated by the virtual motion of a third one originating from the valence band. Relying on interband polarization rather than singularities near the Fermi level, this mechanism …

Charge density wave incommensuration in tise2 systems measured with hard x-ray scattering
Unconventional superconductivity cannot be understood independently of the phases that order around it. Characterizing the charge order in modulated superconductors provides essential information that could reveal a common underlying mechanism. We performed low temperature experiments on 1T-TiSe 2 …
