Floquet真空工程:QCD真空中Laser驱动的手征孤子晶格

Floquet vacuum engineering: Laser-driven chiral soliton lattice in the QCD vacuum

Akihiro Yamada, Naoki Yamamoto

摘要:

当施加一个具有足够大强度和频率的时间周期圆偏振激光场时,QCD真空会发生什么?基于周期驱动系统的Floquet形式主义和系统的低能有效QCD理论,我们证明了对于足够大的频率和临界强度以上,QCD真空对π介子的手征孤子晶格是不稳定的;拓扑孤子的晶体结构自发地打破宇称和连续平移对称性。我们的工作将为新颖的“弗洛凯真空工程”铺平道路。"

英文摘要:

What happens to the QCD vacuum when a time-periodic circularly polarized laser field with a sufficiently large intensity and frequency is applied? Based on the Floquet formalism for periodically driven systems and the systematic low-energy effective theory of QCD, we show that for a sufficiently large frequency and above a critical intensity, the QCD vacuum is unstable against the chiral soliton lattice of pions; a crystalline structure of topological solitons that spontaneously breaks parity and continuous translational symmetries. Our work would pave the way for novel "Floquet vacuum engineering."
