ON SHAPE DEPENDENCE OF HOLOGRAPHIC ENTANGLEMENT ENTROPY IN ADS4/CFT3 WITH LIFSHITZ SCALING AND HYPERSCALING VIOLATION

On shape dependence of holographic entanglement entropy in AdS4/CFT3 with Lifshitz scaling and hyperscaling violation

Abstract We study the divergent terms and the finite term in the expansion of the holographic entanglement entropy as the ultraviolet cutoff vanishes for smooth spatial regions having arbitrary shape, when Purses the gravitational background is a four dimensional asymptotically Lifshitz spacetime with hyperscaling violation, in a certain range of t

A Novel Approach to Calculating the Transmission Accuracy of a Cycloid-Pin Gear Pair Based on Error Tooth Surfaces

Transmission error (TE) and backlash are important parameters used to evaluate the transmission accuracy of cycloid-pin drives.Existing calculation methods are mostly based on two-dimensional tooth profile models, Covers and these methods ignore the influence of some abnormal meshing phenomena caused by profile modifications (PMs), manufacturing er
