光和自由电子 (大图景)

在强场和量子领域中，研究自由电子和光的相互作用。

应用物理目标是实现电子和光场之间的能量、动量和信息的可控转移。

基础物理目标是探索电磁相互作用的深层结构。

• 注：我们关心电子本身，光本身，而不是材料本身。

材料只是“第三者”而已 (third medium)。

但我们也不能否认合适材料的“相位匹配”作用。

关于本课题组的研究目标和动机，“三”言以蔽之：

Goal: “Shaping electron with light, shaping light with electron.”  

— Ido Kaminer (Technion)

哲学: “会不会光就是电，电就是光？” “这你得问She！”   (注：SHE是早期女团)

— Zhaopin Chen (Technion)

Principle: Free electron and photon can exchange energy, momentum, and even information at the quantum level. 

— Yiming Pan (ShanghaiTech) 

Research I:

• Floquet engineering in optics and condensed matters

  Floquet engineering is a paradigm of tailoring and manipulating a system by a periodic drive.

• Momentum gaps (k-gaps) and energy-momentum gaps(ωk-gaps)

• Floquet gauge anomalies in periodically driven systems 

(anomalies are not dangerous)

• Weak measurement and its realizations.

Weak measurement can demonstrate the transition from quantum to classical. 

However, decoherence only leads to the statistics.

• Riemann Hypothesis in quantum physics.                  

• Prompt engineering in daily life and AI for physics

教学理念

有教无类

Equally access to education to all individualswithout discrimination (in Chinese, “有教无类”)

• To educate college students and high school kids：

  The first principle for me is to admit my stupidity in front of them.

• To teach graduate students and postdocs: 

  My job is to support them in achieving success in science and technology.

参与知乎-物理类科普和社区建设

• To teach the public: 

  The most critical aspect of disseminating information to the public in determining: What is NOT science!
