This CAREER award supports a project that will develop a new laser cooling scheme for atomic calcium and apply this scheme to two emerging research topics. The new scheme enables polarization gradient cooling to 1 microKelvin and should allow temperatures 1000 times lower than that currently realized in laser cooled calcium. In collaboration with researchers at NIST-Boulder, the ultracold calcium atoms will be used in an improved optical clock frequency measurement. The atoms will also be used in experiments in dense Rydberg gases and ultracold, strongly coupled, two-component plasmas. The educational component of the activity, in addition to heavy involvement of undergraduate students in the research, will recruit local area secondary school physics teachers as summer research associates and involve them as direct participants in the research projects.

该职业奖支持一个项目，该项目将开发一种新的原子钙激光冷却方案，并将该方案应用于两个新兴的研究课题。新方案使极化梯度冷却到1微开尔文，并且允许温度比目前激光冷却钙实现的温度低1000倍。与NIST-Boulder的研究人员合作，超冷钙原子将用于改进的光学时钟频率测量。这些原子还将用于高密度里德伯气体和超冷、强耦合、双组分等离子体的实验。除了让本科生大量参与研究外，该活动的教育部分还将招募当地中学物理教师作为暑期研究助理，并让他们直接参与研究项目。
