نویسندگان
چکیده
We study the Casimir effect of a membrane embedded in 2+1 dimensions flat cone generated by massive particle located at origin coordinate system. The is an exact solution nonprojectable Hořava theory, similar to general relativity. consider scalar field satisfying Dirichlet boundary conditions, and regularize spectrum using ζ–function technique. In addition, we include effects temperature our analysis. Our results show that force depends on three factors: anisotropic scaling z, mass point particle, temperature.

Asymptotic freedom in Hořava-Lifshitz gravity.
We use the Wetterich equation for foliated spacetimes to study the renormalization group flow of projectable Hořava-Lifshitz gravity coupled to n Lifshitz scalars. Using novel results for anisotropic heat kernels, the matter-induced beta functions for the gravitational couplings are computed explicitly. The renormalization group flow exhibits an UV attractive anisotropic Gaussian fixed point wh...
متن کاملStationary axisymmetric and slowly rotating spacetimes in Hořava-Lifshitz gravity.
Stationary, axisymmetric, and slowly rotating vacuum spacetimes in the Hořava-Lifshitz (HL) gravity are studied, and it is shown that, for any given spherical static vacuum solution of the HL theory (of any model, including the ones with an additional U(1) symmetry), there always exists a corresponding slowly rotating, stationary, and axisymmetric vacuum solution, which reduces to the former, w...
متن کاملStronger constraints on non-Newtonian gravity from the Casimir effect
We review new constraints on the Yukawa-type corrections to Newtonian gravity obtained recently from gravitational experiments and from the measurements of the Casimir force. Special attention is paid to the constraints following from the most precise dynamic determination of the Casimir pressure between the two parallel plates by means of a micromechanical torsional oscillator. The possibility...

متن کاملString theory embeddings of nonrelativistic field theories and their holographic Hořava gravity duals.
We argue that generic nonrelativistic quantum field theories with a holographic description are dual to Hořava gravity. We construct explicit examples of this duality embedded in string theory by starting with relativistic dual pairs and taking a nonrelativistic scaling limit.
