Welcome 👋

I am Kevin Y. Lin, a B.S. candidate in Physics at the Southern University of Science and Technology (SUSTech), Class of 2028.

My primary academic focus is in experimental condensed matter physics, particularly the study of quantum materials using techniques such as scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy (ARPES).

I am especially interested in the electronic structure of quantum materials at the atomic scale, where subtle variations in local symmetry, orbital composition, or lattice distortion can give rise to rich and often unexpected emergent phenomena. Understanding these behaviors not only deepens our knowledge of quantum matter, but also opens up possibilities for discovering new phases with exotic properties such as topological order, unconventional superconductivity, or strongly correlated states.

I am currently conducting research under the supervision of Prof. Jiaxin Yin at SUSTech, focusing on novel quantum phases and topological materials.

Beyond my major, I have a strong personal interest in statistics, especially in Bayesian inference, probabilistic modeling, and the mathematical foundations of statistical reasoning. While not part of my formal curriculum, I find deep intellectual satisfaction in exploring how uncertainty, information, and inference are rigorously understood. ``

Paper Summary: Quantum-limit Chern Topological Magnetism in TbMn₆Sn₆

Author: Kevin Y. Lin Affiliation: Freshman, Southern University of Science and Technology (SUSTech), Shenzhen, Guangdong, China Date: July 8, 2025 Background In Kagome materials with strong spin-orbit coupling and out-of-plane magnetization, spin-polarized Dirac fermions are theoretically possible, analogous to the Haldane model. However, ideal quantum materials are lacking, posing experimental challenges. Key Findings / Evidence of Quantum-limit Chern Magnet 1. Spin-polarized Dirac Cones with Landau Quantization Zero-field STM peak shifts linearly with magnetic field due to the Zeeman effect: ...

Munkres Manifolds Derivations

Let $ M $ be a topological space. Following Munkres, we define $ M $ to be a $ k $-dimensional manifold without boundary if: $ M $ is Hausdorff, $ M $ is second-countable, For every $ p \in M $, there exists an open neighborhood $ U \subset M $ and a homeomorphism: $$ \varphi : U \to V \subset \mathbb{{R}}^k $$ where $ V $ is open in $ \mathbb{{R}}^k $. ...
