Hearing The Quantum

Jayadev Vijayan develops a Fermi quantum gas microscope in the Quantum Optics group in Munich. He prepares an ordered lattice with one atom per site, and then dopes it by adding another atom into the system. This allows him to observe how doping affects the spin ordering of the gas. They claim their images reveal polarons - a quasi-particle important to understanding high-temperature superconductivity. Joannis Koepsell, Jayadev Vijayan, Pimonpan Sompet, Fabian Grusdt, Timon A.
