Coherent control of quantum systems with phase-stable pulses offers enticing new opportunities for lightwave electronics. Here we extend this approach to many-body systems with spin degrees of freedom, demonstrating that a single few-cycle control pulse can create a sizable population asymmetry between the two degenerate polar ground states of the Ising model. This opens a route for femtosecond-scale data processing and storage, allowing one to control the final ground state of a correlated system in an all-optical way.
利用相位稳定脉冲对量子系统进行相干控制为光波电子学带来了诱人的新机遇。在此，我们将这种方法扩展到具有自旋自由度的多体系统，证明单个少周期控制脉冲能够在伊辛模型的两个简并极化基态之间产生可观的粒子数不对称。这为飞秒级数据处理和存储开辟了一条途径，使人们能够以全光方式控制相关系统的最终基态。
