Extracting the quantum geometric tensor of an optical Raman lattice by Bloch-state tomography by Chang-Rui Yi, Jinlong Yu, Huan Yuan, Rui-Heng Jiao, Yu-Meng Yang, Xiao Jiang, Jin-Yi Zhang, Shuai Chen, Jian-Wei Pan

“…Here, we experimentally realize a complete Bloch-state tomography to directly measure the eigenfunction of an optical Raman lattice for ultracold atoms. Through the measured eigenfunction, the distribution of the complete QGT in the Brillouin zone is reconstructed, with which the topological invariants are extracted by the Berry curvature and the distances of quantum states in momentum space are measured by the quantum metric tensor. …”

Synthetic gauge fields in synthetic dimensions: interactions and chiral edge modes by Simone Barbarino, Luca Taddia, Davide Rossini, Leonardo Mazza, Rosario Fazio

“…Synthetic ladders realized with one-dimensional alkaline-earth(-like) fermionic gases and subject to a gauge field represent a promising environment for the investigation of quantum Hall physics with ultracold atoms. Using density-matrix renormalization group calculations, we study how the quantum Hall-like chiral edge currents are affected by repulsive atom–atom interactions. …”

Natural mode entanglement as a resource for quantum communication. by Heaney, L, Vedral, V
