Question

In a potential of this type, transitions between states can be suppressed by tuning the potential to the “magic wavelength.” In a potential of this type, the ratio between an interaction matrix element, U, and a tunneling parameter, J, has a critical value denoting a phase transition. Rubidium atoms in a potential of this type transition between (15[1])superfluid and Mott insulator states as the potential depth is increased. An alternative to the fountain method for making atomic clocks involves a potential of this type which traps atoms using the (*) AC Stark effect. The interference of (10[1])crossed laser beams forms an “optical” analogue of these structures, (-5[2])which in 3 dimensions come in 14 types (-5[1])and are built from primitive, face-centered, (10[1]-5[1])or body-centered unit cells. (10[1])For 10 points, (-5[2])give (10[1])this term for the periodic structure (10[1])formed by crystals. (10[1])■END■ (10[5])

ANSWER: lattices [accept optical lattices or crystal lattices; prompt on periodic potentials or harmonic oscillator potential or anharmonic oscillator potential; prompt on optical potential before “optical”]
