拓扑绝缘体的美在于它们的鲁棒性；它们的表面态受到保护，不受无序和缺陷的影响。
The beauty of topological insulators lies in their robustness; their surface states are protected against disorder and imperfections.
为政仁德深厚,才能使社会安定；做事胸襟宽广,才能够容纳天下万民。
"History is not the past, it is the present. We carry our history with us."
The journey of discovery in physics is not just about finding answers, but about asking the right questions.
