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…
Asymmetric dark matter with a spontaneously broken : self-interaction and gravitational waves
Zien Chen, Kairui Ye, Mengchao Zhang
Motivated by the collisionless cold dark matter small scale structure problem, we propose an asymmetric dark matter model where dark matter particle interact with each other via a…
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}-…
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…
A New Improved Energy-Momentum Tensor and Its Possible Role in Gravity
Tao Lei, Zi-Wei Chen, Zhen-Lai Wang +1
Motivated by a special consideration in quantum measurement, we present a new improved energy-momentum tensor. The new tensor differs from the traditional canonical and symmetric o…
