Material Limitations on the Detection Limit in Refractometry
We discuss the detection limit for refractometric sensors relying on high-Q optical cavities and show that the ultimate classical detection limit is given by min {Δn} ≳ η, with n + iη being the complex refractive index of the material under refractometric investigation. Taking finite Q factors and filling fractions into account, the detection limit declines. As an example we discuss the fundame...
متن کاملthe effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...

Approaching the Heisenberg Limit Without Single-Particle Detection: Supplemental Material
In this supplement, we derive the effective one-axis twisting dynamics of an atomic ensemble coupled to a driven optical cavity [1–3]. This system has been analyzed elsewhere, but we know of no comprehensive treatment using the Lindblad master equation formalism. We also establish an equivalence between the twisting dynamics of the driven cavity scheme and the twisting dynamics of a four-photon...
