- Description
- We propose a class of lattice models realisable in a wide range of setups whose low-energy dynamics exactly resembles Dirac fields subjected to (1+1)-dimensional gravitational backgrounds, including (anti-)de Sitter spacetime. These models are simple 1D chains, where hopping is position-dependent and follows a power-law: t_n propto n^gamma. We find eternal slowdown upon approaching the origin of the lattice in the wave-packets dynamics when gammageq 1, which signals the formation of a black hole event horizon. In contrast, when gamma< 1, the wave-packets bounce off the horizon. These findings pave the way for a new and experimentally viable mimicking of black hole horizons.
