Many-Body Quadrupolar Sum Rule for Higher-Order Topological Insulator
Wonjun Lee, Gil Young Cho, Byungmin Kang
The modern theory of polarization establishes the bulk-boundary correspondence for the bulk polarization. In this paper, we attempt to extend it to a sum rule of the bulk quadrupol…

Metrology of Band Topology via Resonant Inelastic X-ray Scattering
Sangjin Lee, Kyung-Hwan Jin, Byungmin Kang +2
Topology is a central notion in the classification of band insulators and characterization of entangled many-body quantum states. In some cases, it manifests as quantized observabl…

Sign-Problem-Free Variant of Complex Sachdev-Ye-Kitaev Model
Byungmin Kang, Junggi Yoon
We construct a sign-problem free variant of the complex Sachdev-Ye-Kitaev (SYK) model which keeps all the essential properties of the SYK model, including the analytic solvability…
