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…
Frustrated superradiant phases in one- and two-dimensional lattices
Jongjun M. Lee, Myung-Joong Hwang
Understanding how frustration and symmetry breaking shape collective behavior is a central problem in quantum many-body systems. In this work, we investigate this problem in large…
Enhanced dissipative criticality at an exceptional point
Jongjun M. Lee
Exceptional points (EPs) represent non-Hermitian degeneracies where eigenvalues and eigenvectors coalesce, giving rise to enhanced sensitivity and critically damped dynamics. We de…
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…
Universality classes split by strong and weak symmetries
Jongjun M. Lee, Myung-Joong Hwang, Igor Boettcher
Dissipative phase transitions are strongly shaped by the symmetries of the Liouvillian, yet a clear understanding of the quantitative impact of weak and strong symmetries on critic…
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…
Enhanced transverse electron transport via disordered composite formation
Sang J. Park, Hojun Lee, Jongjun M. Lee +3
Transverse electron transport in magnetic materials - manifested in effects such as the anomalous Hall and Nernst effects - holds promise for spintronic and thermoelectric applicat…
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…
Non-Fermi Liquids in Conducting 2D Networks
Jongjun M. Lee, Masaki Oshikawa, Gil Young Cho
We explore the physics of novel fermion liquids emerging from conducting networks, where 1D metallic wires form a periodic 2D superstructure. Such structure naturally appears in ma…
