Nonlinear mode coupling and synchronization of a vacuum-trapped nanoparticle.
We study the dynamics of a laser-trapped nanoparticle in high vacuum. Using parametric coupling to an external excitation source, the linewidth of the nanoparticle's oscillation can be reduced by three orders of magnitude. We show that the oscillation of the nanoparticle and the excitation source are synchronized, exhibiting a well-defined phase relationship. Furthermore, the external source ca...
متن کاملA solution of nonlinear fractional random differential equation via random fixed point technique
In this paper, we investigate a new type of random $F$-contraction and obtain a common random fixed point theorem for a pair of self stochastic mappings in a separable Banach space. The existence of a unique solution for nonlinear fractional random differential equation is proved under suitable conditions.
متن کاملFluorescent Microspheres as Point Sources: A Localization Study
The localization of fluorescent microspheres is often employed for drift correction and image registration in single molecule microscopy, and is commonly carried out by fitting a point spread function to the image of the given microsphere. The mismatch between the point spread function and the image of the microsphere, however, calls into question the suitability of this localization approach. ...
متن کاملFormation of kinetically trapped nanoscopic unilamellar vesicles from metastable nanodiscs.
Zwitterionic long-chain lipids (e.g., dimyristoyl phosphatidylcholine, DMPC) spontaneously form onion-like, thermodynamically stable structures in aqueous solutions (commonly known as multilamellar vesicles, or MLVs). It has also been reported that the addition of zwitterionic short-chain (i.e., dihexanoyl phosphatidylcholine, DHPC) and charged long-chain (i.e., dimyristoyl phosphatidylglycerol...
متن کاملNanoantenna-enhanced ultrafast nonlinear spectroscopy of a single gold nanoparticle
Supplementary Figure S1: Antenna enhancement for another antenna-particle pair: Same graph as in Fig.4 of the main text, but for another antenna-nanoparticle pair. The black curve shows the differential pump-probe spectrum of a single nanoparticle with 50 nm in diameter. As predicted this signal is stronger and also red shifted by about ∆λ = 20 nm compared to the single 40 nm nanoparticle shown...
