Momentum-resolved surface enhanced Raman scattering from a nanowire-nanoparticle junction cavity
Adarsh B. Vasista, Shailendra K. Chaubey, David J. Gosztola +3
Herein we report experimental evidence of directional SERS from molecules situated inside a single nanowire-nanoparticle junction cavity. The emission was confined to a narrow rang…
Accelerating ultrafast spectroscopy with compressive sensing
Sushovit Adhikari, Cristian L. Cortes, Xiewen Wen +5
Ultrafast spectroscopy is an important tool for studying photoinduced dynamical processes in atoms, molecules, and nanostructures. Typically, the time to perform these experiments…
Reactive optical matter: light-induced motility in electrodynamically asymmetric nano-scale scatterers
Yuval Yifat, Delphine Coursault, Curtis W. Peterson +5
From Newtons third law, the principle of actio et reactio, we expect the forces between interacting particles to be equal and opposite. However, non-reciprocal forces can arise. Sp…
Multipolar analysis of electric and magnetic modes excited by vector beams in core-satellite nano-structures
John Parker, Stephen Gray, Norbert Scherer
Core-satellite structures are known to exhibit magnetic modes at optical frequencies and their characterization is important for the development of metamaterials and metafluids. We…
Calculating Nonlocal Optical Properties of Structures with Arbitrary Shape
Jeffrey M. McMahon, Stephen K. Gray, George C. Schatz
In a recent Letter [Phys. Rev. Lett. 103, 097403 (2009)], we outlined a computational method to calculate the optical properties of structures with a spatially nonlocal dielectric…
Finite-difference frequency-domain study of subwavelength lensing in left-handed materials
X. Wang, Stephen K. Gray, George C. Schatz
We show that the finite-difference frequency-domain method is well-suited to study subwavelength lensing effects in left-handed materials (LHM's) and related problems. The method i…
