Nearly-steady-state locked intrinsic localized modes (ILMs) in the quasi-1D antiferromagnet (C(2)H(5)NH(3))(2)CuCl(4) are detected via four-wave mixing emission or the uniform mode absorption. Exploiting the long-time stability of these locked ILMs, repeatable nonlinear switching is observed by varying the sample temperature, and localized modes with various amplitudes are created by modulation of the microwave driver power. This steady-state ILM locking technique could be used to produce energy localization in other atomic lattices.
通过四波混频发射或均匀模式吸收,在准一维反铁磁体(C(2)H(5)NH(3))(2)CuCl(4)中检测到了近稳态锁定本征局域模(ILMs)。利用这些锁定ILMs的长期稳定性,通过改变样品温度观察到了可重复的非线性开关现象,并且通过调制微波驱动功率产生了具有不同振幅的局域模。这种稳态ILM锁定技术可用于在其他原子晶格中产生能量局域化。
