Description
Takuto Tsuno and co-authors report in 2025 gain engineering and atom lasing in a topological edge state built in synthetic dimensions. Open quantum systems interact with their surroundings, and controlling gain is hard in ultracold atoms compared with photonics. The team used selective evaporative cooling to create effective gain in an atomic lattice.
Atoms condensed into an excited edge state of a synthetic lattice built from internal states. The state follows a well-known topological lattice model. Condensation there acts like laser oscillation at a topological edge mode. The result opens a route to topological atom lasers, they argue.
