Transformation optics that mimics the system outside a Schwarzschild black hole
Huanyang Chen, Rong-Xin Miao, Miao Li
We applied the transformation optics to mimic a black hole of Schwarzschild form. Similar properties of photon sphere were also found numerically for the metamaterial black hole. S…
More studies on Metamaterials Mimicking de Sitter space
Miao Li, Rong-Xin Miao, Yi Pang
We estimate the dominating frequencies contributing to the Casimir energy in a cavity of metamaterials mimicking de Sitter space, by solving the eigenvalue problem of Maxwell equat…
Casimir Energy, Holographic Dark Energy and Electromagnetic Metamaterial Mimicking de Sitter
Miao Li, Rong-Xin Miao, Yi Pang
We compute the Casimir energy of the photon field in a de Sitter space and find it to be proportional to the size of the horizon, the same form of the holographic dark energy. We s…
Primordial Non-Gaussianities from the Trispectra in Multiple Field Inflationary Models
Xian Gao, Miao Li, Chunshan Lin
We investigate the primordial non-Gaussianities from the trispectra in multi-field inflation models, which can be seen as generalization of multi-field -inflation and multi-DBI…
A Trouble with Hořava-Lifshitz Gravity
Miao Li, Yi Pang
We study the structure of the phase space in Hořava-Lifshitz theory. With the constraints derived from the action, the phase space is described by five fields, thus there is a lack…
Non-Commutativity, Teleology and GRB Time Delay
Miao Li, Yi Pang, Yi Wang
We propose a model in which an energy-dependent time delay of a photon originates from space-time non-commutativity, the time delay is due to a noncommutative coupling between dila…
