Unconventional quantum criticality in the kicked rotor
Unconventional quantum criticality in the kicked rotor
The quantum kicked rotor (QKR) driven by $d$ incommensurate frequencies realizes the universality class of $d$-dimensional disordered metals. For $d>3$, the system exhibits an Anderson metal-insulator transition which has been observed within the framework of an atom-optics realization. However, the absence of genuine randomness in the QKR reflects in critical …
