Dynamical susceptibility of a near-critical nonconserved order parameter and quadrupole Raman response in Fe-based superconductors
We analyze the dynamical response of a two-dimensional system of itinerant fermions coupled to a scalar boson ϕ, which undergoes a continuous transition towards nematic order with a d-wave form factor. We consider two cases: (a) when ϕ is a soft collective mode of fermions near a Pomeranchuk instabi...
