A Non - Relativistic Weyl Anomaly
نویسنده
چکیده
We examine the Weyl anomaly for a four-dimensional z = 3 Lifshitz scalar coupled to Hořava’s theory of anisotropic gravity. We find a one-loop break-down of scale-invariance at second order in the gravitational background.

Magnetic torque anomaly in the quantum limit of Weyl semimetals
Electrons in materials with linear dispersion behave as massless Weyl- or Dirac-quasiparticles, and continue to intrigue due to their close resemblance to elusive ultra-relativistic particles as well as their potential for future electronics. Yet the experimental signatures of Weyl-fermions are often subtle and indirect, in particular if they coexist with conventional, massive quasiparticles. H...
متن کاملHydrodynamic theory of thermoelectric transport and negative magnetoresistance in Weyl semimetals.
We present a theory of thermoelectric transport in weakly disordered Weyl semimetals where the electron-electron scattering time is faster than the electron-impurity scattering time. Our hydrodynamic theory consists of relativistic fluids at each Weyl node, coupled together by perturbatively small intervalley scattering, and long-range Coulomb interactions. The conductivity matrix of our theory...
متن کاملWeyl Anomaly of 2D Dilaton-Scalar Gravity and Hermiticity of System Operator
Weyl Anomaly in the dilaton-scalar system in 2 dimensional gravity is examined. Discrepancy in recent results by some authors is clarified. We take the heat-kernel regularization for the ultraviolet divergences. In the present approach, the Weyl anomaly depends on the choice of an 2nd order differetial operator for the regularization. We have the freedom of its choice due to the arbitrariness o...

The γ-trace anomaly of supersymmetry current in a supersymmetric gauge theory shares a superconformal anomaly multiplet with the chiral R-symmetry anomaly and the Weyl anomaly, and its holographic reproduction is a valuable test to the AdS/CFT correspondence conjecture. We investigate how the γ-trace anomaly of the supersymmetry current of N = 1 four-dimensional su-persymmetric gauge theory in ...
