Observation and Control of the Magnetic Photogalvanic Effect from Strongly Bound Excitons

Xianfan Nie, Tarun Patel, Hyunggeun Lee +11

Photogalvanic effects arising from the quantum geometry of noncentrosymmetric materials are promising for next-generation light-harvesting devices that do not require a built-in el…

Fully Generalized Spin Models with Strain Effects of Kitaev Spin Liquid Candidate Materials

Pureum Noh, Hyunggeun Lee, Myung Joon Han +1

The $K J Γ Γ^{'}$ spin model-originally derived for an ideal $P 3 ˉ 1 m$ symmetric geometry-has long served as a central framework for understanding candidate Kitaev materials. In reali…

Inversion and Tunability of Van Hove Singularities in $A$ V $_{3}$ Sb $_{5}$ ( $A$ = K, Rb, and Cs) kagome metals

Sangjun Sim, Min Yong Jeong, Hyunggeun Lee +2

To understand the alkali-metal-dependent material properties of recently discovered $A$ V $_{3}$ Sb $_{5}$ ( $A$ = K, Rb, and Cs), we conducted a detailed electronic structure analysis…
