Capacitance bridge measures light-induced force on a cantilever
What the study found The study reports a tabletop interferometer based on a mechanical cantilever that can measure the radiation force exerted by light. It uses a capacitance bridge to detect very small capacitance changes caused by light-driven motion of the cantilever. Why the authors say this matters The authors say the experiment uses equipment…
Review outlines control of reactions in radiofrequency ion traps
—
What the study found Radiofrequency ion traps allow a high degree of control over ion-molecule dynamics, and the review summarizes ways to use that control in chemical reaction studies. It covers trapping and cooling methods, approaches for setting internal quantum states, ways to tune collision energy, and methods for selecting molecular structure. Why the authors…
