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)。

但我们也要合适材料来实现相位匹配和场增强。

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)

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

Research I:

• Floquet engineering in optics and condensed matters: Floquet engineering is a paradigm of tailoring and manipulating a system by a periodic drive [Nature Communications (2022); Laser & Photon. Rev. (2022); Laser & Photon. Rev. (2015)].

• Momentum gaps (k-gaps) and energy-momentum gaps(ωk-gaps) [PRL 130, 233801 (2023)]

• 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 [Physical Review Letters 130, 223403 (2023); ].

• Weak measurement and its realizations. Weak measurement can demonstrate the transition from quantum to classical [Light Science & Applications 12:267 (2023); Nature Physics, 16(12), 1206-1210 (2020).]. However, decoherence only leads to the statistics.

• Riemann Hypothesis in quantum physics. Riemann hypothesis equals to Quantum mechanics?

• Prompt engineering for writing and free electron quantum neural networks

Prompt engineering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.

自由电子量子神经网络:

I know nothing yet... But I will.

PDENet 数据库:

算力，算法，数据，数据，数据...

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！

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

· 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!
