Interaction-tuned Anderson versus Mott localization
AE Antipov, Y Javanmard, P Ribeiro, S Kirchner - Physical Review Letters, 2016 - APS
Disorder or sufficiently strong interactions can render a metallic state unstable, causing it to
turn into an insulating one. Despite the fact that the interplay of these two routes to a …

Theoretical description of pump/probe experiments in electron-mediated charge-density-wave insulators
In this review, we develop the formalism employed to describe charge-density-wave
insulators in pump/probe experiments that use ultrashort driving pulses of light. The theory …

Coexistence of charge-density wave and ferromagnetism in NiMnGa
We demonstrate the existence of a charge-density-wave (CDW) associated with an
incommensurate periodic lattice distortion on Ni 2 MnGa surface in the ferromagnetic state …

Gapless regime in the charge density wave phase of the finite dimensional Falicov-Kimball model
The ground-state density of states of the half-filled Falicov-Kimball model contains a charge-
density-wave gap. At finite temperature, this gap is not immediately closed, but is rather filled …
