Quantum Oscillation Signatures of Monopole Charge in Nodal-Ring Semimetals
Aravind Karthigeyan, Yoonseok Hwang, Bohm-Jung Yang +1
Topological semimetals host band nodes characterized by quantized invariants that can appear in bulk responses, yet some invariants remain hidden from standard probes. In particula…

Spin-momentum Locking and Topological Vector Charge Response with Conserved Spin
Yoonseok Hwang, Penghao Zhu, Taylor L. Hughes
Spin-momentum locking plays a fundamental role in spintronics and, more broadly, is an important concept in condensed matter physics. In 2D and 3D, spin-momentum locking typically…

Transversality-Enforced Tight-Binding Models for 3D Photonic Crystals aided by Topological Quantum Chemistry
Antonio Morales-Pérez, Chiara Devescovi, Yoonseok Hwang +5
Tight-binding models can accurately replicate the band structure and topology of crystalline systems. They have been widely used in solid-state physics due to their versatility and…
