Unified perspective on single cyclotron electron with radiation-reaction from classical to quantum
Qiang Chen, Peifeng Fan, Jianyuan Xiao
We show a unified physical picture of single cyclotron electron with radiation-reaction, which bridges the classical electron models and quantum mechanical self-consistent field th…
High-order Field Theory and Weak Euler-Lagrange-Barut Equation for Classical Relativistic Particle-Field Systems
Peifeng Fan, Qiang Chen, Jianyuan Xiao
It is widely accepted that conservation laws, especially energy-momentum conservation, have fundamental importance for both classical and quantum systems in physics. A widely used…
Gauge invariant canonical symplectic algorithms for real-time lattice strong-field quantum electrodynamics
Qiang Chen, Jianyuan Xiao, Peifeng Fan
A class of high-order canonical symplectic structure-preserving geometric algorithms are developed for high-quality simulations of the quantized Dirac-Maxwell theory based strong-f…
Symmetries and Local Conservation Laws of Variational Schemes for the Surface Plasmon Polaritons
Qiang Chen, Xiaojun Hao, Chuanchuan Wang +3
The relation between symmetries and local conservation laws, known as Noether's theorem, plays an important role in modern theoretical physics. As a discrete analog of the differen…
Variational Schemes and Geometric Simulations for a Hydrodynamic-Electrodynamic Model of Surface Plasmon Polaritons
Qiang Chen, Lifei Geng, Xiang Chen +3
A class of variational schemes for the hydrodynamic-electrodynamic model of lossless free-electron gas in a quasineutral background is developed for high-quality simulations of sur…
Hamiltonian structure and connection-dynamics of Weyl gravity
Qian Chen, Yongge Ma
A crucial property of Weyl gravity is its conformal invariance. It is shown how this gauge symmetry is exactly reflected by the two constraints in the Hamiltonian framework. Since…
