We show that a quantum phase transition from ergodic to many-body localized (MBL) phases can be induced via periodic pulsed manipulation of spin systems. Such a transition is enabled by the interplay between weak disorder and slow heating rates. Specifically, we demonstrate that the Hamiltonian of a weakly disordered ergodic spin system can be effectively engineered, by using sufficiently fast coherent controls, to yield a stable MBL phase, which in turn completely suppresses the energy absorption from external control field. Our results imply that a broad class of existing many-body systems can be used to probe nonequilibrium phases of matter for a long time, limited only by coupling to external environment.

动态诱导多体定位

我们表明，可以通过周期性的自旋系统脉冲操作来诱导从遍历到多体局部（MBL）相的量子相变。这种转变是由弱无序和缓慢加热速率之间的相互作用实现的。具体来说，我们证明了通过使用足够快的相干控制可以有效地设计弱无序遍历旋转系统的哈密顿量，以产生稳定的MBL相，从而完全抑制了外部控制场的能量吸收。我们的结果表明，现有种类繁多的现有多体系统可用于长时间探测物质的非平衡相，而这仅受与外部环境耦合的限制。
