Beam filamentation instability drives deuterium-tritium fusion with polarized neutron emission
Guanqi Qiu, Deji Liu, Dongchi Cai +3
Filamentation instabilities are generally regarded as detrimental to fast-electron transport in fusion plasmas because they increase beam divergence and redistribute deposited ener…

Magnetic island structures in relativistic laser-driven plasma channels
Dongchi Cai, Zheng Gong, Guanqi Qiu +3
We develop a theoretical model for self-generated magnetic islands in relativistic laser-driven channels in near-critical-density plasmas. The islands arise from the nonlinear supe…

Optimization of laser-driven proton acceleration in a near-critical-density plasma
Guanqi Qiu, Qianyi Ma, Deji Liu +5
Optimizing laser and plasma parameters is crucial for enhancing accelerated proton energy in laser-driven proton acceleration with finite laser energy for applications such as canc…
