    Casimir effect of a rough membrane in 2 + 1 Hořava Lifshitztheory
    (2024) Claudio Bórquez; Byron Droguett
    We investigate the Casimir effect of a rough membrane within the framework of the Hořava–Lifshitz the-ory in 2+1 dimensions. Quantum fluctuations are induced by an anisotropic scalar field subject to Dirichlet boundary conditions. We implement a coordinate transformation to render the membrane completely flat, treating the remaining terms associated with roughness as a potential. The spectrum is obtained through perturbation theory and regularized usingtheζ-function method. We present an explicit example of a membrane with periodic border. Additionally, we consider the effect of temperature. Our findings reveal that the Casimir energy and force depend on roughness, the anisotropic scaling factor and temperature.
