We propose a new experimental test bed that uses ions in the collective ground state of a static trap to study the analogue of quantumfield effects in cosmological spacetimes, including the Gibbons–Hawking effect for a single detector in de Sitter spacetime, as well as the possibility of modeling inflationary structure formation and the entanglement signature of de Sitter spacetime. To date, pr...
