Periodic Motion of Sedimenting Flexible Knots

Giovanni Dietler, Krishnan Thyagarajan, Andrzej Stasiak

We study the dynamics of knotted deformable closed chains sedimenting in a viscous fluid. We show experimentally that trefoil and other torus knots often attain a remarkably regular horizontal toroidal structure while sedimenting, with a number of intertwi ...

Augmenting Second Harmonic Generation Using Fano Resonances in Plasmonic Systems

Olivier Martin, Jérémy Butet, Krishnan Thyagarajan

Significant augmentation of second harmonic generation using Fano resonances in plasmonic heptamers made of silver is theoretically and experimentally demonstrated. The geometry is engineered to simultaneously produce a Fano resonance at the fundamental wa ...

Second-harmonic generation from periodic arrays of arbitrary shape plasmonic nanostructures: a surface integral approach

Olivier Martin, Jérémy Butet, Benjamin Gallinet, Krishnan Thyagarajan

A surface integral formulation for the second-harmonic generation (SHG) from periodic metallic-dielectric nano-structures is described. This method requires the discretization of the scatterers' surface in the unit cell only. All the physical quantities in ...

Ultrasensitive Optical Shape Characterization of Gold Nanoantennas Using Second Harmonic Generation

Olivier Martin, Jérémy Butet, Krishnan Thyagarajan

Second harmonic generation from plasmonic nanoantennas is investigated numerically using a surface integral formulation for the calculation of both the fundamental and the second harmonic electric field. The comparison between a realistic and an idealized ...
