Atom imaged in ultracold gas

Photonics.com: A high-resolution microscope has been developed to image individual atoms in an ultracold quantum gas, marking the first time scientists have detected single atoms in a crystalline structure made solely of light, called a Bose Hubbard optical lattice. Physicists at Harvard University created the microscope as part of efforts to use ultracold quantum gases to understand and develop novel quantum materials.
