The Hall effects of vortex light in optical materials
Wei-Si Qiu, Li-Li Yang, Dan-Dan Lian +1
For light, its spin can be independent of the spatial distribution of its wave function, whereas its intrinsic orbital angular momentum does depend on this distribution. This diffe…
Effective ray equations for vortex light and their application in an optical waveguide
Wei-Si Qiu, Dan-Dan Lian, Peng-Ming Zhang
Beyond its spin, light can also carry intrinsic orbital angular momentum (IOAM), termed as vortex light. In this study, we derive effective ray equations for vortex light by applyi…
Gravitational spin Hall effect of electrons in Schwarzschild metric
Dan-Dan Lian, Wei-Si Qiu, Peng-Ming Zhang
In this study, we derive the non-relativistic Hamiltonian for electrons within the Schwarzschild metric from covariant Dirac equations, using both the weak field approximation and…
Gravitational orbital Hall effect of vortex light in Lense-Thirring metric
Wei-Si Qiu, Dan-Dan Lian, Peng-Ming Zhang
Vortex light, characterized by an intrinsic orbital angular momentum aligned with its propagation direction, is described through vortex electromagnetic waves. Similar to the gravi…
The motion of twisted particles in a stellar gravitational field
Dan-Dan Lian, Peng-Ming Zhang
In this work, we explore the motion of a twisted particle possessing intrinsic orbital angular momentum (OAM) as it traverses a weak stellar gravitational field, which we approxima…
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}-…
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…
