Building a Potassium MOT
A magneto-optical trap (MOT) was developed in order to cool and trap potassium atoms. This required construction of a mechanism for tuning and locking the frequency of a trap and repump laser in order to maintain the correct energy transitions needed to ensure trapping of the atoms. Once the lasers’ frequencies were locked, the beams were combined and amplified and can now be combined with lase...
متن کاملSOT for MOT
In this paper we present a robust tracker to solve the multiple object tracking (MOT) problem, under the framework of tracking-by-detection. As the first contribution, we innovatively combine single object tracking (SOT) algorithms with multiple object tracking algorithms, and our results show that SOT is a general way to strongly reduce the number of false negatives, regardless of the quality ...
متن کاملThe Norwegian type-anaphor det
This paper gives a description of the Norwegian type anaphor det ('that') and proposes a formal representation of it in the HPSG framework. This identity-of-sense anaphor is interpreted as referring to a (new) set of entities of the same type as its antecedent. Its antecedent has to be either indefinite or a definite NP that is likely to introduce a brand new discourse referent. Whereas the typ...
متن کاملDet-extremal cubic bipartite graphs
Let G be a connected k–regular bipartite graph with bipartition V (G) = X ∪Y and adjacency matrix A. We say G is det–extremal if per(A) = |det(A)|. Det–extremal k–regular bipartite graphs exist only for k = 2 or 3. McCuaig has characterized the det–extremal 3–connected cubic bipartite graphs. We extend McCuaig’s result by determining the structure of det–extremal cubic bipartite graphs of conne...
متن کاملDet-Det Correlations for Quantum Maps: Dual Pair and Saddle-Point Analyses
An attempt is made to clarify the ballistic non–linear sigma model formalism recently proposed for quantum chaotic systems, by looking at the spectral determinant Z(s) = Det(1− sU) for quantized maps U ∈ U(N), and studying the correlator ωU (s) = ∫ dθ |Z(eiθs)|2. By identifying U(N) as one member of a dual pair acting in the spinor representation of Spin(4N), the expansion of ωU (s) in powers o...
