Scattering theory without large-distance asymptotics in arbitrary dimensions
Wen-Du Li, Wu-Sheng Dai
In conventional scattering theory, by large-distance asymptotics, at the cost of losing the information of the distance between target and observer, one imposes a large-distance as…
Thermo field dynamics approach for entropy of spacetime
Yu-Zhu Chen, Wen-Du Li, Wu-Sheng Dai
A thermo field dynamics approach for calculating the entropy of a spacetime is suggested. It is exemplified through the Rindler spacetime, the Milne spacetime, the Boulware spaceti…
Heat-kernel approach for scattering
Wen-Du Li, Wu-Sheng Dai
An approach for solving scattering problems, based on two quantum field theory methods, the heat kernel method and the scattering spectral method, is constructed. This approach con…
Statistical problem of ideal gas in general 2-dimensional regions
Ci Song, Wen-Du Li, Pardon Mwansa +1
In this paper, based on the conformal mapping method and the perturbation theory, we develop a method to solve the statistical problem within general 2-dimensional regions. We cons…
Scattering theory without large-distance asymptotics: scattering boundary condition
Wen-Du Li, Wu-Sheng Dai
By large-distance asymptotics, in conventional scattering theory, at the cost of losing the information of the distance between target and observer, one arrives at an explicit expr…
