Uniaxial Lifshitz Point at O(ǫ
The critical exponents νL2, ηL2 and γL2 of a uniaxial Lifshitz point are calculated at two-loop level using renormalization group and ǫL-expansion techniques. We introduced a new constraint involving the loop momenta along the competition axis, which allows to solve the two-loop integrals. The exponent γL2 obtained using our method is in good agreement with numerical estimates based on Monte Ca...
متن کاملSurface critical exponents at a discontinuous bulk transition
Systems with a bulk first-order transition can display diverging correlation lengths close to a surface. This surface induced disordering yields a special type of surface criticality. Using extensive numerical simulations we study surface quantities in the two-dimensional Potts model with a large number of states q which undergoes a discontinuous bulk transition. The surface critical exponents ...
متن کاملField Theory at a Lifshitz Point
We construct the general renormalizable actions for the scalar field and gauge field at a Lifshitz point characterized by the dynamical critical exponent z. The Lorentz invariance is broken down in the UV region, but is recovered in the IR limit. Even though the theories are UV complete, the speed of light is related to the momentum by z(k/M)z−1 which can go to infinity in the UV limit for z ≥ ...
متن کاملRelativistic Quantum Gravity at a Lifshitz Point
We show that the Hořava theory for the completion of General Relativity at UV scales can be interpreted as a gauge fixed Tensor-Vector theory, and it can be extended to an invariant theory under the full group of four-dimensional diffeomorphisms. In this respect, although being fully relativistic, it results to be locally anisotropic in the time-like and space-like directions defined by a famil...
متن کاملCPN−1 Models at a Lifshitz Point
We consider CPN−1 models in d+1 dimensions around Lifshitz fixed points with dynamical critical exponent z, in the large-N expansion. It is shown that these models are asymptocially free and dynamically generate a mass for the CPN−1 fields for all d = z. We demonstrate that, for z = d = 2, the initially nondynamical gauge field acquires kinetic terms in a way similar to usual CPN−1 models in 1 ...
