Using spectral regularisation, we compute the Weyl anomaly and express the anomaly generating functional of the quantum effective action through a collective scalar degree of freedom of all quantum vacuum fluctuations. Such a formulation allows us to describe induced gravity on an equal footing with the anomaly-induced effective action, in a self-consistent way. We then show that requiring stab...

We study effects associated with the chiral anomaly for a cascading SU(N+ M)×SU(N) gauge theory using gauge/gravity duality. In the gravity dual the anomaly is a classical feature of the supergravity solution, and the breaking of the U(1) R-symmetry down to Z2M proceeds via the Higgs mechanism.

A bidimensional empirical mode decomposition (BEMD) program on a MATLAB platform was effectively used to handle gravity signals for the Tongshi gold field. This yielded a two-dimensional intrinsic mode function (IMF3) image that meticulously depicts the spatial distribution relationship between various gold deposits and the different geological units of the gold field. By combining the IMF3 ima...

We present the preferential filtering method for gravity anomaly separation based on Green equivalent-layer concept and Wiener filter. Compared to the conventional upward continuation and the preferential continuation, the preferential filtering method has the advantage of no requirement of continuation height. The method was tested both on the synthetic gravity data of a model of multiple rect...

Introduction: Understanding the lunar gravity field can provide fundamental information about lunar internal structure, bulk composition, heat flow, and the duration of volcanism and tectonism. We aim to utilize the gravity field from the Gravity Recovery and Interior Laboratory (GRAIL) mission to reconstruct the history of lunar volcanic history. The high-resolution GRAIL gravity maps show tha...

As one of the world’s oldest continents, Australia has experienced a complicated geological and geomorphological history. As such, the gravity field of Australia behaves differently to that reported in other countries. This paper investigates the relative roughness of three types of gravity anomaly (freeair, refined Bouguer and topographic-isostatic) using statistical and graphical comparisons,...

Gravity surveys are an important research topic in geophysics and geodynamics. This paper investigates a method for high accuracy large scale gravity anomaly data reconstruction. Based on the airborne gravimetry technology, a flight test was carried out in China with the strap-down airborne gravimeter (SGA-WZ) developed by the Laboratory of Inertial Technology of the National University of Defe...

The gravity anomaly field over the whole Earth obtained by the GOCE satellite is a revolutionary tool to reveal geologic information on a continental scale for the large areas where conventional gravity measurements have yet to be made. It is, however, necessary to isolate the near-surface geologic signal from the contributions of thickness variations in the crust and lithosphere and the isosta...

Quantum theory of 2d gravity is examined by including a special quantum correction, which corresponds to the open string loop corrections and provides a new conformal anomaly for the corresponding σ model. This anomaly leads to the condensation of the tachyon, and the resulatnt effective theory implies a possibility of extending the 2d gravity to the case of c > 1. ∗ e-mail address: gouroku@don...
