Self-Consistent Dynamics of Electron Radiation Reaction via Structure-Preserving Geometric Algorithms for Coupled Schrödinger-Maxwell Systems
Jacob Matthew Molina, Hong Qin
Classically, a charged particle in a magnetic field emits radiation, losing momentum and experiencing the Abraham-Lorentz (AL) / Landau-Lifshitz (LL) radiation reaction (RR) force.…
Hidden free energy released by explicit parity-time-symmetry breaking
Hong Qin, William Dorland, Ben Y. Israeli
It is shown that the familiar two-stream instability is the result of spontaneous parity-time (PT)-symmetry breaking in a conservative system, and more importantly, explicit PT-sym…
Quantum Inspiration, Classical Advantage: Dequantized particle algorithm for the nonlinear Vlasov-Poisson system
Hong Qin, Michael Q. May, Jacob Molina
We present a dequantization algorithm for the Vlasov--Poisson (VP) system, termed the dequantized particle algorithm, by systematically dequantizing the underlying many-body quantu…
Counting topological interface modes using simplicial characteristic classes
N. Bohlsen, I. Y. Dodin, H. Qin
A computational approach for predicting the number of topological interface modes (TIMs) in hermitian systems using the spectral flow - monopole (SFM) correspondence is presented.…
Second quantization of nonlinear Vlasov-Poisson system for quantum computation
Michael Q. May, Hong Qin
The Vlasov-Poisson equations, fundamental in plasma physics and astrophysical applications, are rendered linear, finite-dimensional, and discrete by second quantization. Conditions…
Gap modes in Arnold tongues and their topological origins
Andrew Brown, Hong Qin
Gap modes in a modified Mathieu equation, perturbed by a Dirac delta potential, are investigated. It is proved that the modified Mathieu equation admits stable isolated gap modes w…
