Abstract:
The last decade has seen a huge growth in the construction of chiral systems to expand the scope of chiroptical applications. Dependence of chiroptical response on molecular conformation typically leads to low chiroptical intensities of chiral systems that feature several conformations in solution. In this respect, allenes were employed for the preparation of open and cyclic oligomers as well as molecular cages, presenting remarkable chiroptical responses in solution. Their molecular chirality was also transferred to metal surfaces, yet photoisomerization of allenes limited their further explo

Abstract:
The potential for enhancing the optical activity of natural chiral media using engineered nanophotonic components has been central in the quest toward developing next-generation circular-dichroism spectroscopic techniques. Through confinement and manipulation of optical fields at the nanoscale, ultrathin optical elements have enabled a path toward achieving order-of-magnitude enhancements in the chiroptical response. Here, we develop a model framework to describe the underlying physics governing the origin of the chiroptical response in optical media. The model identifies optical activity to o

Abstract:
Chiral metasurfaces exploit structural asymmetry to control circular polarized light, presenting new possibilities for the design of optical devices, specifically in the dynamic control of light and enhanced optical sensing fields. This study employed theoretical and computational methods to examine the chiroptical properties of a bilayer crescent chiral metasurface, demonstrating the effect of the angle of rotation on the chiroptical response. We particularly investigated the changes in transmittance, electric field distribution, and circular dichroism (CD) across various rotation angles. The

Abstract:
Chiral materials, which show different optical behaviors when illuminated by left or right circularly polarized light due to broken mirror symmetry, have greatly impacted the field of optical sensing over the past decade. To improve the sensitivity of chiral sensing platforms, enhancing the chiroptical response is necessary. Metasurfaces, which are two-dimensional metamaterials consisting of periodic subwavelength artificial structures, have recently attracted significant attention because of their ability to enhance the chiroptical response by manipulating amplitude, phase, and polarization o

Abstract:
Quantum mechanical methods are becoming increasingly useful and applicable tools to complement and support experiment. Nonetheless, some barriers to further applications of theoretical models still remain. A coupled cluster singles and doubles (CCSD) calculation, a reliable textit{ab initio} method, scales approximately on the order of ${cal O}(N^6)$, where $N$ is a measure of the system size. This unfortunately limits the use of such high-accuracy methods to relatively small systems. Coupled cluster property calculations must be used in conjunction with reduced-scaling methods in

Abstract:
Light-matter interactions at the nanoscale have been widely studied over the past few decades. In particular, the interaction of light with asymmetric nanostructures has harbored the interests of chemists, biologists and physicists alike. The world around us is largely constituted of asymmetric structures such as DNA, sugars, amino-acids, proteins, enzymes which form the backbone of every living matter. Structures which cannot be superimposed on their mirror images are termed as chiral structures. Naturally occurring chiral objects display unique optical properties such as Circular Dichroism (

Chiral metamaterials, known for their chiroptical effects, exhibit asymmetric responses to left- and right-circularly polarized light, resulting in higher circular dichroism (CD) compared to natural materials1,2. Currently, some chiral metamaterials, exemplified by helices3, offers inherent handedness, but their 3D nanostructure fabrication can be complex2.
