Emergent Discrete Space in a Generic Lifshitz Model    [PDF]

Subir Ghosh
We have considered the possibility of Spontaneous Symmetry Breaking in momentum space in a generic Lifshitz scalar model, which is a non-relativistic model with higher spatial derivative terms. We have explicitly shown that a spatially varying ground state, (termed as a flowing ground state), minimizes the energy as compared to a constant valued condensate. We have studied stability property as well as the fluctuation spectra above the flowing ground state. The most interesting observation is that this flowing ground state requires a discretization of space coordinate.
