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…
Extraordinary spin density and energy back-flow under interference
Zhen-Lai Wang, Dan-Dan Lian, Xiang-Song Chen
A novel phenomenon was reported recently that the "local optical spin density" based on Poynting vector might be counter-intuitively opposite to the integrated spin orientation whi…
Gravity-induced geometric spin Hall effect as a probe of universality of free fall of quantum particle
Zhen-Lai Wang, Xiang-Song Chen
We present a novel fundamental effect that for the matter waves the space-averaging free-fall point of quantum particles undergoes a spin-dependent transverse shift in the gravitat…
Anomalous Geometric Spin Hall Effect of Light?
Zhen-Lai Wang, Xiang-Song Chen
The geometric spin Hall effect of light (GSHEL), similar to the spin Hall effect of light, is also a spin-dependent shift of the centroid of light beam's intensity (energy flux), b…
Gravitational Coupling from Active Gravity
Tao Lei, Zi-Wei Chen, Zhen-Lai Wang +1
We attempt to construct a gravitational coupling by pre-selecting an energy-momentum tensor as the source for gravitational field. The energy-momentum tensor we take is a recently…
New Energy-Momentum and Angular Momentum Tensors with Applications to Nucleon Structure
Zhen-Lai Wang, De-Tian Yang, Zi-Wei Chen +2
We present a new type of energy-momentum tensor and angular momentum tensor. They are motivated by a special consideration in quantum measurement: Given a wave in mutual eigen-stat…
