    "abstract": "Avoided crossings are common in the quasienergy spectra of strongly driven\nnonlinear quantum wells. In this paper we examine the sinusoidally driven\nparticle in a square potential well to show that avoided crossings can alter\nthe structure of Floquet states in this system. Two types of avoided crossings\nare identified: on type leads only to temporary changes (as a function of\ndriving field strength) in Floquet state structure while the second type can\nlead to permanent delocalization of the Floquet states. Radiation spectra from\nthese latter states show significant increase in high harmonic generation as\nthe system passes through the avoided crossing.",
