Noether-Charge Realization of Diffeomorphism Algebra

Han-Ying Guo, Chao-Guang Huang, Xiaoning Wu

It is shown in the covariant phase space formalism that the Noether charges with respect to the diffeomorphism generated by vector fields and their horizontal variations in general…

General Relativistic Effects on Quantum Interference and the Principle of Equivalence

K. K. Nandi, Yuan-Zhong Zhang

Using a novel approach, we work out the general relativistic effects on the quantum interference of de Broglie waves associated with thermal neutrons. The unified general formula i…

Effect of Earth's rotation on the trajectories of free-fall bodies in Equivalence Principle Experiment

C. G. Shao, Y. Z. Zhang, J. Luo +1

Owing to Earth's rotation a free-fall body would move in an elliptical orbit rather than along a straight line forward to the center of the Earth. In this paper on the basis of the…

Analog of the Fizeau Effect in an Effective Optical Medium

K. K. Nandi, Yuan-Zhong Zhang, P. M. Alsing +2

Using a new approach, we propose an analog of the Fizeau effect for massive and massless particles in an effective optical medium derived from the static, spherically symmetric gra…

Black hole entropy without brick walls

Li Xiang

The properties of the thermal radiation are discussed by using the new equation of state density motivated by the generalized uncertainty relation in the quantum gravity. There is…

Planckian Scattering Beyond the Eikonal Approximation in the Functional Approach

Nguyen Suan Han, Nguyen Nhu Xuan

In the framework of functional integration the non-leading terms to leading eikonal behavior of the Planckian-energy scattering amplitude are calculated by the straight-line path a…

Black Hole Mass Formula Is a Vanishing Noether Charge

Xiaoning Wu, Han-Ying Guo, Chao-Guang Huang +1

The Noether current and its variation relation with respect to diffeomorphism invariance of gravitational theories have been derived from the horizontal variation and vertical-hori…
