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…
