Published in 2025 at "Advanced science"

DOI: 10.1002/advs.202505834

Abstract: Magneto‐optical excitations in antiferromagnetic d systems can originate from a multiplicity of light‐spin and spin‐spin interactions, as the light and spin degrees of freedom can be entangled. This is exemplified in van der Waals systems… read more here.

Published in 2018 at "Microscopy and Microanalysis"

DOI: 10.1017/s1431927618008358

Abstract: Optical properties of low-dimensional materials are strongly governed by excitons and their interactions with defects. For instance, non-radiative exciton decays in carbon nanotubes are presumably happened at defects and result in the low luminescence quantum… read more here.

Published in 2017 at "Nanoscale"

DOI: 10.1039/c7nr06175g

Abstract: The bottom-up fabrication of graphene nanoribbons (GNRs) has opened new opportunities to specifically tune their electronic and optical properties by precisely controlling their atomic structure. Here, we address excitation in GNRs with periodic structural wiggles,… read more here.

Published in 2020 at "Physical review letters"

DOI: 10.1103/physrevlett.124.047401

Abstract: The interaction of light with solids gives rise to new bosonic quasiparticles, with the exciton being-undoubtedly-the most famous of these polaritons. While excitons are the generic polaritons of semiconductors, we show that for strongly correlated… read more here.

Published in 2024 at "Physical review letters"

DOI: 10.1103/physrevlett.133.146502

Abstract: We develop a theory that explains the low-energy optical excitations near 1.5 eV observed by optical experiments in NiPS_{3}. Using ab initio methods, we construct a two-band Hubbard model for two effective Ni orbitals. The dominant effective… read more here.
