Gauge dependence of spontaneous radiation spectrum of relativistic atomic beam under non-uniform electrostatic field
Xue-Nan Chen, Yu-Hang Luo, Xiang-Song Chen
Gauge theory requires physical observables to be gauge-independent. However, ever since Lamb noticed the problem of gauge selection in calculating atomic spontaneous radiation spec…
More on difference between angular momentum and pseudo-angular momentum
Qi Dai, Zi-Wei Chen, Bang-Hui Hua +1
We extend the discussion on the difference between angular momentum and pseudo-angular momentum in field theory. We show that the often quoted expressions in [Phys.Rev.B 103, L1004…
Arbitrariness and Usefulness of the Expressions of Elastic wave's Energy, Momentum and Angular Momentum
Zi-Wei Chen, Bang-Hui Hua, Xiang-Song Chen
Elastic angular momentum is an emerging field, with some controversies on the correct field-theory expressions and the decomposition of longitudinal and transverse components. Moti…
Repeatedly readable state, spontaneous collapse, and quantum/classical boundary
Xiao-Fu Peng, Yu-Hang Luo, Jiang Zhu +5
We propose a model to identify the quantum/classical boundary. The model introduces a spontaneous collapse of state superposition: $\frac{d}{dt} ρ_{ij} =-\frac{i}{\hbar}[H,ρ]_{ij}-…
Gauge dependence of spontaneous radiation spectrum in a time-dependent relativistic non-perturbative Coulomb field
Xue-Nan Chen, Yu-hang Luo, Xiang-Song Chen
We extend the "gauge choice" problem Lamb noticed to include a time-dependent relativistic non-perturbative Coulomb field, which can be produced by a cluster of relativistic charge…
On the Uniqueness of Einstein-Cartan Theory: Lagrangian, Covariant Derivative and Equation of Motion
Zi-Wei Chen, Run Diao, Xiang-Song Chen
In the standard Einstein-Cartan theory(EC), matter fields couple to gravitation field through the Minimal Coupling Procedure(MCP), yet leaving the theory an ambiguity: applying MCP…
