Intrinsic orbital Hall effect in a nonuniform electric field
Min Ju Park, Jongjun M. Lee, Hyun-Woo Lee
Geometric analysis of electronic Bloch states offers a universal framework for understanding electronic properties, yet its role in the transport of orbital angular momentum remain…
Comparing the orbital angular momentum and magnetic moment of magnons in the Kagome antiferromagnet with negative spin chirality
Youngjae Jeon, Jongjun M. Lee, Suik Cheon +1
The orbital dynamics of magnons have recently drawn interest due to their potential roles in thermal and orbital transport phenomena in magnetic insulators. In this study, we inves…
Universal intrinsic orbital dynamics from Berry curvature in electronic two-band systems
Jongjun M. Lee
The geometric structure of quantum states plays a fundamental role in determining the intrinsic dynamics of electrons in solids. In this work, we study the geometric origin of orbi…
Diverging entanglement of critical magnons in easy-axis antiferromagnets
Jongjun M. Lee, Hyun-Woo Lee, Myung-Joong Hwang
We study the instability of antiferromagnets with easy-axis anisotropy under a magnetic field, uncovering single or even multiple phase transitions at the boundary between non-coll…
Orbital Edelstein effect of electronic itinerant orbital motion at edges
Jongjun M. Lee, Min Ju Park, Hyun-Woo Lee
In the study of orbital angular momentum (OAM), the focus has been predominantly on the intra-atomic contribution. However, recent research has begun to shift towards exploring the…
Dyakonov-Perel-like Orbital and Spin Relaxations in Centrosymmetric Systems
Jeonghun Sohn, Jongjun M. Lee, Hyun-Woo Lee
The Dyakonov-Perel (DP) mechanism of spin relaxation has long been considered irrelevant in centrosymmetric systems since it was developed originally for non-centrosymmetric ones.…
Topological magnon-photon interaction for cavity magnonics
Jongjun M. Lee, Myung-Joong Hwang, Hyun-Woo Lee
The study of cavity magnonics and topological insulators has made significant advances over the past decade, however the possibility of combining the two fields is still unexplored…
Cavity magnonics with easy-axis ferromagnet: Critically enhanced magnon squeezing and light-matter interaction
Jongjun M. Lee, Hyun-Woo Lee, Myung-Joong Hwang
Generating and probing the magnon squeezing is an important challenge in the field of quantum magnonics. In this work, we propose a cavity magnonics setup with an easy-axis ferroma…
