Giant and flexible toroidal circular dichroism from planar chiral metasurface

open access: yesAPL Materials
Chirality, a fundamental concept describing an object cannot superpose with its mirror image, is crucial in optics and photonics and leads to various exotic phenomena, such as circular dichroism and optical activity.

Photoelectron Circular Dichroism at the Few-cycle Limit [PDF]

open access: yesEPJ Web of Conferences, 2019
Photoelectron circular dichroism (PECD) was investigated for methyloxirane with intense few-cycle pulses. The observed PECD shows a dependence on electron energy. This may signify an influence of the chiral potential on the outgoing electron’s trajectory.

Chiral Nanohoops as an Efficient Spin Polarization System

open access: yesAdvanced Functional Materials, EarlyView.
Chiral conjugated nanohoops with a central dibenzopentalene unit exhibit 90% spin polarization at low voltage and high conductivity. These properties make them ideal components in molecular spintronics applications. Abstract A central challenge in molecular spintronics is to achieve a high spin polarization at low operating voltages and ambient ...

Asymmetric Synthesis and Absolute Configuration Assignment of a New Type of Bedaquiline Analogue

open access: yesMolecules, 2015
Bedaquiline is the first FDA-approved new chemical entity to fight multidrug-resistant tuberculosis in the last forty years. Our group replaced the quinoline ring with a naphthalene ring, leading to a new type of triarylbutanol skeleton.

Tunable circular dichroism of chiral metamaterial based on phase transition of vanadium dioxide (VO2)

open access: yesMaterials Research Express, 2020
The circular dichroism effect characterized by different optical responses between left-handed and right-handed circularly polarized lights is widely applied for biological monitoring, analytical chemistry, and plasmonic sensing.

Nuclear spin circular dichroism

open access: yesThe Journal of Chemical Physics, 2014
Recent years have witnessed a growing interest in magneto-optic spectroscopy techniques that use nuclear magnetization as the source of the magnetic field. Here we present a formulation of magnetic circular dichroism (CD) due to magnetically polarized nuclei, nuclear spin-induced CD (NSCD), in molecules.

Chiral SURMOFs for Vibrational Circular Dichroism: Multiscale Modeling and Experimental Insights

open access: yesAdvanced Functional Materials, EarlyView.
The use of solid‐state vibrational circular dichroism (VCD) for MOFs is still somewhat unexplored, and in this work, it is shown that chiral surface‐anchored MOFs (SURMOFs) grown on CaF2 provide an excellent platform for VCD. Experimental results are validated through multiscale modeling, showing strong agreement across multiple spectroscopic ...

First principles theory of chiral dichroism in electron microscopy applied to 3d ferromagnets

open access: yes, 2007
Recently it was demonstrated (Schattschneider et al., Nature 441 (2006), 486), that an analogue of the X-ray magnetic circular dichroism (XMCD) experiment can be performed with the transmission electron microscope (TEM). The new phenomenon has been named
