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…
Revealing inverted chirality of hidden domain wall states in multiband systems without topological transition
Seung-Gyo Jeong, Sang-Hoon Han, Tae-Hwan Kim +1
Chirality, a fundamental concept from biological molecules to advanced materials, is prevalent in nature. Yet, its intricate behavior in specific topological systems remains poorly…
Topological Domain-Wall States Hosting Quantized Polarization and Majorana Zero Modes Without Bulk Boundary Correspondence
Sang-Hoon Han, Myungjun Kang, Moon Jip Park +1
Bulk-boundary correspondence is a concept for topological insulators and superconductors that determines the existence of topological boundary states within the tenfold classificat…
