Dear Staten Island,
I'm not licensed to practice in NY but I doubt you have standing to evict a neighbor, that would be up to the landlord.
Since the LL is aware of the situation and neglecting to take effective curative action, like eviction, they may be constructively evicting you. I would suggest taking your lease agreement to a local attorney to help you craft a letter to your management stating the severity of the issue and how it has effected your sleep and use of the apartment. In addition, if they continue to refuse to correct the issue you will be forced to withhold rent until they do evict her. Withholding rent can be dangerous though (a threat may be enough), and I highly encourage you to consult with a local NY attorney first. You can also talk with your other neighbors, if there is any, and see if they suffer the same issues with the noisy neighbor.
Good Luck. I hope this is helpful.
