Vector exceptional points with strong superchiral fields
Tong Wu, Weixuan Zhang, Huizhen Zhang +12
Exceptional points(EPs), branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce, are ubiquitous in non-Hermitian systems. Many novel properties and…
Competition of Chiroptical Effect Caused by Nanostructure and Chiral Molecules
Tong Wu, Jun Ren, Rongyao Wang +1
The theory to calculate circular dichroism (CD) of chiral molecules in a finite cluster with arbitrarily disposed objects has been developed by means of T-matrix method. The intera…
Plasmon-induced strong interaction between chiral molecules and orbital angular momentum of light
Tong Wu, Rongyao Wang, Xiangdong Zhang
Whether or not chiral interaction exists between the optical orbital angular momentum (OAM) and a chiral molecule remains unanswered. So far, such an interaction has not been obser…
Strongly Enhanced Raman Optical Activity in Molecules by Magnetic Response of Nanoparticles
Tong Wu, Xiuhui Zhang, Rongyao Wang +1
An analytical theory for the surface-enhanced Raman optical activity (SEROA) with the magnetic response of the substrate particle has been presented. We have demonstrated that the…
Giant chiroptical effect caused by the electric quadrupole
Tong Wu, Weixuan Zhang, Rongyao Wang +1
Recently, there is a great interest in studying ultrasensitive detection and characterization of biomolecules using plasmonic particles, because they are of considerable importance…
Amplification of Molecular Chiroptical Effect by Low-loss Dielectric Nanoantennas
Weixuan Zhang, Tong Wu, Rongyao Wang +1
We report here chiroptical amplification effect occurring in the hybrid systems consisting of chiral molecules and Si nanostructures. Under resonant excitation of circularly polari…
