论文摘要
我们研究了理想的自旋系统的响应，该系统与强振荡磁场和热环境相互作用，对弱探测磁场的响应。我们证明，即使产生的平均磁化的迹象也取决于驱动场的幅度，并且在没有时间周期性强迫的情况下，其绝对值可能明显大于平衡磁化。由于基本的浮雕状态职业概率取决于系统浴耦合的精确形式，因此这种效果的未来测量可能有可能建立一项特别创新的研究线，提供有关非平衡热力学的信息，并在探测平衡系统时通常会隐藏的数量访问数量。
We study the response of ideal spin systems which are interacting with both a strong oscillating magnetic field, and a thermal environment, to a weak probing magnetic field. We demonstrate that even the sign of the resulting mean magnetization depends on the amplitude of the driving field, and that its absolute value can be significantly larger than the equilibrium magnetization in the absence of time-periodic forcing. Since the underlying Floquet-state occupation probabilities are determined by the precise form of the system-bath coupling, future measurements of such effects have the potential to establish a particularly innovative line of research, providing information on nonequilibrium thermodynamics, and giving access to quantities which usually remain hidden when probing equilibrium systems.
