On volumes of hyperideal tetrahedra with constrained edge lengths

, 2019
Hyperideal tetrahedra are the fundamental building blocks of hyperbolic 3-manifolds with geodesic boundary. The study of their geometric properties (in particular, of their volume) has applications also in other areas of low-dimensional topology, like ...

Circularly Polarized Light Emission From Single Chiral Hedgehog Particles Coated with Nanofilms of Achiral Perovskites

Advanced Materials, EarlyView.
Left‐ and right‐handed circularly polarized light emission (CPLE) is observed from chiral “hedgehog” particles (CHIPs) coated with a nanofilm of achiral perovskite, with spectroscopic bands specific to the perovskites and chirality specific to the template CHIPs. Careful analysis of optical activity indicates that the CPLE of perovskite luminescence is

Hyperbolic Dehn filling in dimension four

, 2017
We introduce and study some deformations of complete finite-volume hyperbolic four-manifolds that may be interpreted as four-dimensional analogues of Thurston's hyperbolic Dehn filling.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
