Abstract

A phenomenological model accounts for the calculation of incommensurate ordering wave vectors (IC) in several Ce- and U-based f-electron itinerant compounds (CePtSn, CePdSn, CeNiSn, CeRhIn₅, URu₂Si₂, CeNiAsO, CeCu_(6-x)Au_x, UNi₂Al₃, CeCuSn) as well as in BSSCO, Rb₂ZnBr₄, MnSi and prototypical IC system Chromium metal. This model is justified by a many-body topological one-dimensional (1-D) Dirac Hamiltonian after center of mass transformation on a chiral set of momenta defined by a local expansion of crystallographic Bragg planes. Implications for the emergence of long range bulk states driven by fluctuations with this model are discussed.
