Graviton physics: Quantum field theory of gravitons, graviton noise and gravitational decoherence -- a concise tutorial
Jen-Tsung Hsiang, Hing-Tong Cho, Bei-Lok Hu
The detection of gravitational waves in 2015 ushered in a new era of gravitational wave astronomy capable of probing into the strong field dynamics of black holes and neutron stars…
Noise kernels of stochastic gravity in conformally-flat spacetimes
H. T. Cho, B. L. Hu
The central object in the theory of semiclassical stochastic gravity is the noise kernel which is the symmetric two point correlation function of the stress-energy tensor. Using th…
Inflaton fluctuations in the presence of cosmological defects
Hing-Tong Cho, Kin-Wang Ng, I-Chin Wang
We study quantum fluctuations of a free massless scalar field during inflation in the presence of a point, line, or plane defect such as a black hole, cosmic string, or domain wall…
Stress-energy Tensor Correlators of a Quantum Field in Euclidean and spaces via the generalized zeta-function method
H. T. Cho, B. L. Hu
In this paper we calculate the vacuum expectation values of the stress-energy bitensor of a massive quantum scalar field with general coupling to N-dimensional Euclidean spaces and…
Correlations of the stress-energy tensor in AdS spaces via the generalized zeta-function method
H. T. Cho, B. L. Hu
We calculate the vacuum expectation values of the stress-energy bitensor of a minimally coupled massless scalar field in anti-de Sitter (AdS) spaces. These correlators, also known…
Quasi-normal modes for doubly rotating black holes
H. T. Cho, Jason Doukas, Wade Naylor +1
Based on the work of Chen, Lü and Pope, we derive expressions for the dimensional metric for Kerr-(A)dS black holes with two independent rotation parameters and all other…
