摘要：
一维准周期系统与二维整数量子霍尔物质之间众所周知的映射，在存在驱动的情况下同样适用。本文探究时变电场对 Harper-Hofstadter 材料输运性质和相图的影响。我们考虑任意偏振的光照射在强磁场中的二维电子气上；该系统可映射为同时承受相位子驱动和偶极驱动的一维准晶。我们表明，这种广义驱动产生了一种镶嵌式相图，其特征是具有嵌套的、受对偶性保护的金属–绝缘体转变图案。圆偏振或椭圆偏振光可以产生扩展临界相，为无需精细调节至临界点即可实现波函数多重分形开辟了一条新途径。我们还详细描述了利用晶格囚禁的超冷原子在实验上实现这些现象的路径。
英文摘要：
The well-known mapping between 1D quasiperiodic systems and 2D integer quantum Hall matter can also be applied in the presence of driving. Here we explore the effect of time-varying electric fields on the transport properties and phase diagram of Harper-Hofstadter materials. We consider light of arbitrary polarization illuminating a 2D electron gas at high magnetic field; this system maps to a 1D quasicrystal subjected to simultaneous phasonic and dipolar driving. We show that this generalized driving generates a tessellated phase diagram featuring a nested duality-protected pattern of metal-insulator transitions. Circularly or elliptically polarized light can create an extended critical phase, opening up a new route to achieving wavefunction multifractality without fine-tuning to a critical point. We describe in detail a path to experimental realization of these phenomena using lattice-trapped ultracold atoms.
