Experimental observation and manipulation of optical tornado waves
Lai Chen, Li-Gang Wang
We report experimental generation and manipulation of optical tornado waves (ToWs). By controlling the self-focusing length, total angular momentum, and foci deviation of ToWs, the…
Theory of light propagation in arbitrary two-dimensional curved space
Chenni Xu, Li-Gang Wang
As an analog model of general relativity, optics on some two-dimensional (2D) curved surfaces has been increasingly paid attention to in the past decade. Here, in light of Huygens-…
Bidirectional optical non-reciprocity in a multi-mode cavity optomechanical system
Muhib Ullah, Xihua Yang, Li-Gang Wang
Optical non-reciprocity, a phenomenon that allows unidirectional flow of optical field is pivoted on the time reversal symmetry breaking. The symmetry breaking happens in the cavit…
Light chaotic dynamics in the transformation from curved to flat surfaces
Chenni Xu, Itzhack Dana, Li-Gang Wang +1
Light propagation on a two-dimensional curved surface embedded in a three-dimensional space has attracted increasing attention as an analog model of four-dimensional curved spaceti…
Rainbow Spacetime from a Nonlocal Gravitational Uncertainty Principle
Omar El-Refy, Syed Masood, Li-Gang Wang +1
Occurrence of spacetime singularities is one of the peculiar features of Einstein gravity, signalling limitation on probing short distances in spacetime. This alludes to the existe…
The large scale structure formation in an expanding universe
Mir Hameeda, Behnam Pourhassan, Syed Masood +3
In this paper, we analyze the effects of expansion on large scale structure formation in our Universe. We do that by incorporating a cosmological constant term in the gravitational…
