  • Abstract Is it feasible to alter the ground-state properties of a material by engineering its electromagnetic environment? Inspired by theoretical predictions1,2,3,4,5,6,7,8,9,10,11,12, experimental realizations of such cavity-controlled properties without optical excitation are beginning to emerge13,14,15,16,17,18,19. Here we devised and implemented a new platform to realize cavity-altered materials. Single crystals of hyperbolic van der Waals (vdW) compounds provide a resonant electromagnetic environment with enhanced density of photonic states and prominent mode confinement20,21,22,23,24. W
