H.K. was supported an Erwin Schrödinger junior research fellowship. I started working on the problem under consideration while writing my PhD thesis. I am thankful to my advisor David Damanik for the support during this process. Furthermore, I wish to thank Michael Goldstein and Svetlana Jitomirskaya for insightful discussions to the process of creation of gaps. Last, I wish to thank Mark Embree without whose help, I would probably not been able to produce the numerical results in Appendix A.
