Quantum-vortex excitons beyond band topology
Jin-Hyung Choi, Sang-Hoon Han, Young-Kwon Han +3
Optically exciting a typical low-dimensional semiconductor produces a nodeless \(s\)-type exciton as its lowest-energy bound state. Here, we explain how Coulomb phase matching stab…

Enhancement of exciton radius near a band-gap closing through quantum geometry
Jin-Hyung Choi, Sang-Hoon Han, Young-Kwon Han +3
Exciton engineering traditionally focuses on modifying semiclassical material properties, such as the effective mass and dielectric screening, while largely overlooking the quantum…
