Following the recent successful experimental manipulation of entangled C atoms on the surface of Diamond, we calculate the decoherence of the electron spin in Nitrogen Vacancy NV centers of Diamond via a nonperturbative treatment of the time-dependent Greens function of a Central-Spin model in order to identify the Replica Symmetry Breaking mechanism associated with intersystem mixing between t...

Two types of micron-diamond films were prepared on YG6 substrate by hot filament chemical vapor deposition(HFCVD) method. Morphology and orientation of crystalline growth were evaluated by SEM and XRD. Diamond film coated tools and sapphire wafer’ surface before and after lapping experiment  were contrasted. The results indicated that a significant change in Raman spectrum of two types of micro...

Abstract. In this article we design the semi-implicit finite volume scheme for coherence enhancing diffusion in image processing and prove its convergence to the weak solution of the problem. The finite volume methods are natural tools for image processing applications since they use piecewise constant representation of approximate solutions similarly to the structure of digital images. They ha...

43 A diverging diamond interchange (DDI), also called a double crossover diamond interchange 44 (DCD), is a relatively new interchange type in the U.S. Due to its many advantages over the 45 conventional diamond interchanges such as higher capacity and lower delay, there has been a 46 growing interest in its analysis methodologies and operational strategies. DDIs have shown 47 particularly high...

A minimal-parameter tight-binding theory incorporating explicit use of nonorthogonality of the basis is used to generate a transferable scheme for germanium. Good results are obtained for high-pressure bulk phases and vibrational frequencies. Diamond structure is found to be the ground state even when compared with the clathrate structure. The results for clusters show good agreement with ab in...

This paper reviews existing studies and investigates thermal operational regimes of diamond bit during drilling operations. The operating temperature of the diamond core drill is studied under bench condition and an optimal thermal range are presented. Based on this study, it was noted that glazing of diamond tools is observed at temperatures less than 327°C, and normal wear of diamond tools is...

Evaluation and prediction of performance of diamond wire saw is one of the most important factors involved in planning the dimension stone quarries. The wear rate of diamond wire saw can be investigated as a major criterion to evaluate its performance. The wear rate of diamond wire saw depends upon non-controlled parameters related to rock characteristics and controlled parameters related to ch...

A more complete understanding of entanglement entropy in a covariant manner could inform the search for quantum gravity. We build on work this direction by extending previous results to disjoint regions $1+1$D. investigate scalar field intervals within causal set framework, using spacetime commutator and correlator, $i\mathbf{\Delta}$ $\mathbf{W}$ (or Pauli-Jordan Wightman functions), respectiv...
