Still fiction; it relies on magic, i.e. things not known to actually exist.

  Magic operates in ways we don't understand. I think we understand negative energy density, we just don't know if it's possible in reality.

When you propose things are possible if only X material with some magical property necessary for thing to work, that's speculative fiction. Especially when those constructs only make sense mathematically. Math isn't physics, but physics is math, there's an important implication there.
