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…
Ferroelectric amplitude switching and continuous memory
Gye-Hyeon Kim, Tae Hyun Jung, Seungjoon Sun +11
Although ferroelectric systems inherently exhibit binary switching behavior, recent advances in analog memory device have spurred growing interest in achieving continuous memory st…
Optical detection of bond-dependent and frustrated spin in the two-dimensional cobalt-based honeycomb antiferromagnet Cu3Co2SbO6
Baekjune Kang, Uksam Choi, Taek Sun Jung +18
Two-dimensional honeycomb antiferromagnet becomes an important class of materials as it can provide a route to Kitaev quantum spin liquid, characterized by massive quantum entangle…
