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和场增强的作用。

关于本课题组的研究目标和动机，“一”言以蔽之：

· 哲学: “潘兄，会不会光就是电，电就是光？” 

— Zhaopin Chen (Technion)

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

— Ido Kaminer (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, and they are ubiquitous associated with quantum vacuum and topology. We are focusing on exploring anomalies in driven systems.

• 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. Riemann hypothesis equals to Quantum mechanics?

• Prompt engineering in daily life and AI for quantum physics

提示语:

Now you are a physicist. You are very good at quantum mechanics, light and matter interactions, and condensedmatter physics. You can clearly explain the history and definitions of many concepts. You can derive toy models to explain many effects. You are also good at simulation software. You can find out the reals scientific problem and do a great research. You are my supervisor, you canteach and guide to do a real science. Do not reply instantly - if you have any questions about this prompt, ask me. If you are ready, ask me to give you the text. 

Here is my question: what is the time evolution of free electron wave packet in free space?

Let's think step by step.

ChatGPT使用三原则:

Principle 1: be very specific in yourinstructions.

Principle 2: is to ask GPT-3 to break itswork into small chunks.

Principle 3: ask GPT-3 to check and improve its own output.

Research II:

• Ultrafast electron generation and manipulation, and strong-field electron photon coupling at discontinuity. 

• Design an ultrafast photoelectron gun and realize multi-photon free-free transition for low-energy free electrons.

• Floquet quantum simulators: optics, microwave, sounds, atoms and free electrons.

科学原理：

一言以蔽之，实现和探测超快电子和超快光子的量子纠缠！

基础科学价值和产品化应用前景：

首先，结合光学探测器和直接电子探测器实现时间关联符合测量，用于研究自由电子和光子的量子纠缠。其次，完成平台搭建后，进行优化和升级，并最终实现产品化，实现“超快电子量子显微镜”可广泛使用的实验平台！

· To educate college students&kids: The first principle for me is to admit my stupidity in front of them.

· To teach graduate students&postdocs: My job is to support them in achieving success in science and technology.

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