Spontaneous Emission of an Inertial Multi-Level Atom in a Spacetime with a Reflecting Plane Boundary
《Chinese Physics Letters》2006年第8期2012-2015,共4页朱致英 余洪伟 
Supported by the National Natural Science Foundation of China under Grant Nos 10375023 and 10575035, the Programme for NCET （No 04-0784）, and the Key Project of the Ministry of Education of China （No 205110）.
We calculate the contributions of the vacuum fluctuations and radiation reaction to the rate of change of the mean atomic energy for a multi-level hydrogen atom in the multipolar coupling scheme in a spacetime with a ...

Lower Bounds on Negative Energy Densities for the Scalar Field in Flat Spacetime
《Chinese Physics Letters》2006年第1期25-28,共4页舒维星 余洪伟 任中洲 吴普训 李飞 
Supported by the National Natural Science Foundation of China under Grant Nos 10375023, 10575035 and 10125521, the Program for NCET （No 04-0784）, the Key Project of Chinese Ministry of Education （No 205110）, and the National Major State Basic Research and Development Programme of China （G2000077400）.
We obtain a lower bound on the spacetime-weighted average of the energy density for the scalar field in four-dimensional flat spacetime. The bound takes the form of a quantum inequality. The inequality does not rely o...

Lorentz Invariance and Brownian Motion of Test Particles with Constant Classical Velocity in Electromagnetic Vacuum
《Chinese Physics Letters》2005年第12期3017-3020,共4页张佳林 余洪伟 
Supported by the National Natural Science Foundation of China under Grant Nos 10375023 and 10575035, the Program for NCET （04-0784）, the Key Project of the Ministry of Education of China （205110）.
We show that the velocity and position dispersions of a test particle with a nonzero constant classical velocity undergoing Brownian motion caused by electromagnetic vacuum fluctuations in a space with plane boundarie...

Radiation Rate of a Two-Level Atom in a Spacetime with a Reflecting Boundary
《Chinese Physics Letters》2005年第10期2481-2484,共4页陆世专 余洪伟 
Supported by the National Natural Science Foundation of China under Grant No 10375023, the Program for NCET （No 04-0784）, and the Key Project of the Ministry of Education of China （No 205110）.
We study a two-level atom in interaction with a real massless scalar quantum field in a spacetime with a reflecting boundary. We calculate the rate of change of the atomic energy for the atom. The presence of the boun...

Random Motion of a Charged Test Particle with a Classical Constant Velocity in Vacuum in a Cylindrical Spacetime
《Chinese Physics Letters》2005年第10期2485-2488,共4页张佳林 余洪伟 
Supported by the National Natural Science Foundation of China under Grant No 10375023, the Program for NCET （No 04-0784）, and the Key Project of the Ministry of Education of China （No 205110）.
We examine the random motion of a charged test particle with a nonzero classical velocity driven by quantum electromagnetic vacuum fluctuations in a cylindrical spacetime and calculate both the velocity and position d...

Relic Gravitational Waves and Trans-Planckian Physics
《Chinese Physics Letters》2005年第9期2161-2164,共4页吴普训 余洪伟 
Supported by the National Natural Science Foundation of China under Grant No 10375023, the Program for NCET （No 04-0784）, and the Key Project of the Ministry of Education of China （No 205110）.
Assuming that the effects of trans-Planckian physics are encoded in the choice of initial conditions, mode by mode, for vacuum states at the time when its wavelength becomes equal to the scale of new physics （Planck...
