吳玉書老師指導的量子元件理論研究室又稱介觀物理理論研究室，目前研究的方向是基於石墨烯的電子元件的物理研究。研究的手段是理論分析(圖一)，當然數值計算有時也是必要的(圖二)。有經驗的博士班同學和碩士班同學會彼此緊密合作，完成研究的問題。每周一次meeting(圖三)，可以和老師深入討論研究的問題，此外，平時也可以直接去老師的辦公室討論，在與老師頻繁的交流之中，可以學到非常多東西。

圖一 在黑板上作理論推導，然後討論物理。	圖二 數值分析。
圖三 Meeting進行中。

老師鼓勵同學在學術討論會中，報告研究成果，和其他研究人員交流學習(圖四)。討論會有時用英文進行，是提昇自己語言和表達能力的好機會。圖五為吳老師研究生參加物理年會的留影。

同學之間除了討論研究主題與課業，也會一起出遊和聚餐(圖六)，聯絡感情。已經畢業的學長姐也常回來和學弟妹聊天，分享經驗。

研究室規模不大，成員之間感情緊密，老師就像是慈父一樣，是個溫馨的家庭。在研究室學習到對物理的深入了解，和與其他同學間廣泛的交流學習，將成為以後在業界和學界發展，最堅實的基礎，也是最美好的回憶。
