    Dynamical response and competing orders in two-band Hubbard model

  • Original language description

    We present a dynamical mean-field study of two-particle dynamical response functions in a two-band Hubbardmodel across several phase transitions. We observe that the transition between the excitonic condensate andspin-state ordered state is continuous with a narrow strip of supersolid phase separating the two. Approachingtransition from the excitonic condensate is announced by softening of the excitonic mode at theMpoint of theBrillouin zone. Inside the spin-state ordered phase there is a magnetically ordered state with 2×2 periodicity,which has no precursor in the normal phase.
