Cherenkov radiation is generally believed to be threshold-free in hyperbolicmetamaterials owing to the extremely large photonic density of states in classical localframework. Although recent advances in nonlocal and quantum plasmonics extend ourunderstanding of light-matter interactions in metamater...
