Strange metal from incoherent bosons

The breakdown of the celebrated Fermi liquid theory in strange metal phase is central enigma correlated quantum matter. Motivated by recent experiments reporting short-lived carriers, along with ubiquitous observations modulated excitations diagram cuprates, we propose a model for this phase. We introduce bosons emerging from remnants pair density wave as additional current carriers These bosonic are finite momentum Cooper pairs and thus carry twice electronic charge, its net spin can either be zero or one arising two spin-$1/2$ electrons. show that such capture famous linear relationship resistivity temperature manifests Drude form ac-conductivity Planckian dissipation rate. Furthermore, incoherent hence do not contribute to Hall conductivity. electron spin-triplet symmetry also reproduce recently observed in-field magnetoresistance [P.
