Electromagnetic helicity flux density for radiative systems
Zhen-Yu Heng, Jiang Long, Run-Ze Yu +1
We show that the helicity flux density is distinguished from magnetic helicity by analysing Hopf solitons. The electromagnetic (EM) helicity flux and the magnetic helicity are Cher…

Quantum flux operators for Carrollian diffeomorphism in general dimensions
Ang Li, Wen-Bin Liu, Jiang Long +1
We construct Carrollian scalar field theories in general dimensions, mainly focusing on the boundaries of Minkowski and Rindler spacetime, whose quantum flux operators form a faith…
