We present a versatile electric trap for the exploration of a wide range of quantum phenomena in the interaction between polar molecules. The trap combines tunable fields, homogeneous over most of the trap volume, with steep gradient fields at the trap boundary. An initial sample of up to 10(8), CH(3)F molecules is trapped for as long as 60 s, with a 1/e storage time of 12 s. Adiabatic cooling down to 120 mK is achieved by slowly expanding the trap volume. The trap combines all ingredients for opto-electrical cooling, which, together with the extraordinarily long storage times, brings field-controlled quantum-mechanical collision and reaction experiments within reach.
我们提出了一种通用的电阱，用于探索极性分子相互作用中广泛的量子现象。该阱结合了可调谐场，在阱体积的大部分区域内均匀，在阱边界处具有陡峭的梯度场。初始样品多达 10^8 个 CH（3）F 分子被捕获长达 60 秒，存储时间为 12 秒。通过缓慢扩展阱体积，可以实现 120 mK 的绝热冷却。该阱结合了光电制冷的所有成分，再加上异常长的存储时间，使得场控制的量子力学碰撞和反应实验成为可能。
