Abstract: An alkali-metal dispenser to dispense highly pure rubidium in a high-vacuum environment while not negatively impacting the high-vacuum pressure level. The alkali-metal dispenser is operable in various vapor-deposition applications or to provide a highly pure elemental-alkali metal in cold-atom magneto-optical traps.

Abstract: A piezoelectric rotary optical mount including a clamp including a first hole to hold a hollow member, wherein a contact between the clamp and the hollow member generates a coefficient of friction; a bias element adjacent to the first hole to apply a force to control rotational movement of the hollow member by adjusting the coefficient of friction; and a piezoelectric element to actuate the bias element to apply the force. The clamp may include a housing body including a first end and a second end, wherein the first hole extends in a first axis through the housing body to accommodate the hollow member; a pair of elongated cutout regions extending from the first hole towards the second end to define the bias element; and a second hole adjacent to at least one of the cutout regions to accommodate the piezoelectric element.

Abstract: A method and system for algebraically generating precise magnetic potentials along the axis of a cold atom waveguide. Sets of paired conductors may provide control over the even and odd contributions of the polynomial potential along one axis of the trap. Various field configurations can be realized, including double wells, triple wells, and filtered harmonic traps with suppression of higher order terms. An example of a system disclosed herein may be a suitable dual-layer atom chip, with modest experimental requirements, that allows independent tuning of terms up to fourth order.
