Is the CS-R8000-11 (11-28T) compatible with Shimano 105 R7000 groupset?

Yes — Shimano 11-speed cassettes are cross-compatible within the same speed standard. The CS-R8000 cassette mounts on any Shimano 11-speed freehub body and works with 105 R7000, Ultegra R8000 or Dura-Ace R9100 derailleurs and levers.

Do I need a specific chain for this cassette?

Yes — use a Shimano HG-EV 11-speed chain (CN-HG701, CN-HG901 or equivalent). 11-speed chains are narrower than 10-speed and must be matched to an 11-speed cassette for correct meshing and shift performance.
