Tunable atom-trapping based on a plasmonic chiral metamaterial
Nanophotonics, 2019 Chiral metamaterials provide a very convenient way to actively regulate the light field via external means, which is very important in nanophotonics.

Half-quantum vortices on c-axis domain walls in chiral p-wave superconductors
New Journal of Physics, 2020 Chiral superconductors are two-fold degenerate and domains of opposite chirality can form, separated by domain walls. There are indications of such domain formation in the quasi two-dimensional putative chiral p-wave superconductor Sr _2 RuO _4 , yet no ...

Chiral-induced angular momentum radiation in single molecular junctions
, 2023 We study angular momentum radiation from electrically-biased chiral single molecular junctions using the nonequilibrium Green's function method. Using single and double helical chains as examples, we make connections between the ability of a chiral ...

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis
Advanced Materials, EarlyView.A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Advanced Materials, EarlyView.Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

PhotonicsMulti-band circular dichroism (CD) with spectral tunability is highly desirable for chiral metasurface-based sensing and polarization control. In this work, we propose a mid-infrared (MIR) metal–insulator–metal (MIM) chiral metasurface absorber composed ...

Microsecond-range optical shutter for unpolarized light with chiral nematic liquid crystal
AIP Advances, 2015 A fast electro-optic shutter is fabricated and demonstrated. The device works independently of the polarization state of the incoming light beam. Modulation between 3% transmission and 60% transmission is obtained within a wavelength range of 50 nm with ...

Three-dimensional topological twistronics
Physical Review Research, 2020 We introduce a theoretical framework for the concept of three-dimensional (3D) twistronics by developing a generalized Bloch band theory for 3D layered systems with a constant twist angle θ between successive layers.
