Multifrequency optical lattice for dynamic lattice-geometry control

Realization of 87Rb Bose–Einstein Condensates in Higher Bands of a Hexagonal Boron-Nitride Optical Lattice

“…[22,23] So far, bosonic atoms have been transferred to not only 𝑠-and 𝑝-bands, but also 𝑑-and 𝑓 -bands in bipartite square, triangular and hexagonal lattices. [16][17][18][19]21,22,[24][25][26][27][28][29][30][31][32][33][34] Recent studies also report that fermionic atoms and Feshbach molecules are prepared in higher Bloch bands of a square lattice. [35,36] However, the higher-orbital atoms possess shorter lifetime, owing to the collision-induced band relaxation.…”
