今天的我们，在这个微醺的冬夜里，聊着的和想着的更多的还是要更加自由地表达出个体生命对于世界和人生的看法，在张量网络和蒙特卡洛的空间中，在电子的浩瀚宇宙里，我们寻找的是让我们内心平静的角落，就像根特的街灯、树影和水波。我们应该努力把自身和所生存的环境改造成和这里一般的祥和富足而又幽默顽皮的人和社会，而不是再退回科举和八股的两千年的死循环里。陆徵祥神父的个性解放也好，看破名利也好，最终皈依也好，在他的时代都是少有的个例。今日不再应该如此了，今天我们实现个体生命的自由、圆满的表达，是发自天性的本能追求，是社会演进到现在这个程度自然的呼声，不是万一开倒车就可以把我们拉回头去的。我们的争取就应该像这个根特的微醺的冬夜，散发着微光，也平静地扩散到每个爱思考和爱自由的人的心里。Continue reading

若干年前，卡洛开始在中国物理学会的《物理》杂志上创作他的专栏《量子多体中的呐喊与彷徨》，间或将其中文章扩写或优先发表在《返朴》上。世间以量子物理为对象的科普何其多，但卡洛的这组聚焦在强关联物理的科普少见地做到了「以相对浅显易懂的语言解释复杂科学概念」，此外更独特的是，他的文字饱含了一个以创造性精神为根本追求的人的性情，除了自由探索的欢欣，还有苦闷、忧愁和颓放。由是发展下去，该专栏后来还衍生了的另几个专栏《科学遐思》、《量子多体中的坟》和《量子多体中的野草》，这些文字还仍在继续，仍在感染着新的读者。在科研人追求资源、经费、「帽子」和「科举功名」的今天，看似热闹实则浮躁的氛围锈蚀着象牙塔。发现和创造是最个体的、最纯粹的、最自由的精神活动。如果你也极度珍视自身生命价值，想必也会对作者讲谈科学之时迸发的那种坚硬的抵抗有共鸣和欣赏。Continue reading

Researchers from the University of Hong Kong, including Drs. Hongyu Lu, Bin-bin Chen and Prof. Zi Yang Meng, teamed up with Profs. Kai Sun from the University of Michigan and Han-Qing Wu from Sun Yat-sen University, discovered different ways of ordering electrons in 2D quantum materials. In particular, the research team focused on the interplay between smectic order and topological order. The exotic states and thermal phase transitions exhibiting such features are expected to be accessed in future experiments. Continue reading

A recent study, led by Professor Zi Yang MENG and co-authored by his PhD student Menghan SONG of HKU Department of Physics, in collaboration with researchers from the Chinese University of Hong Kong, Yale University, University of California, Santa Barbara, Ruhr-University Bochum and TU Dresden, has unravelled some of the secrets concealed within the deconfined quantum critical points. Their findings, recently published in the prestigious journal Science Advances, push the boundaries of modern physics and offer a fresh perspective on how quantum matter operates at these enigmatic junctures.

On April 16, 2025, Mr. Hongyu Lu marked a pivotal achievement by successfully defending his Ph.D. thesis, entitled "Numerical studies of fractional quantum anomalous Hall states: Emergent forms, collective excitations, and phase transitions". His clear and compelling presentation of his research findings from his time at HKU, along with his confident responses to impromptu questions, earned high praise from the Examining Committee, which included Prof. Xi Dai from HKUST, and Profs. Wang Yao and Dong-Keun Ki from HKU. Congratulations to Dr. Hongyu Lu! We wish him continued success and look forward to his contributions as an emerging leader in theoretical condensed matter physics. Continue reading
世有 moiré，然后有 super-moiré。Moiré 者常有，而 super-moiré 不常有。
Moiré 之 super 者，其原胞尺度可达百纳米，向之作者不知其能 super 而制也。
是 super-moiré 也，其成于常规 moiré 之量子干涉效应，波粒二象性之力良有以也。
以百纳米之原胞，所含磁通之量亦增百倍，Brown-Zak 振荡正比于磁场之现象，昭然于世也。
噫！Brown-Zak，侯世达诸前辈得见今日之数据，其必曰“微斯人，吾谁与归”矣。

A collaboration between Mr. Ting-Tung Wang, Mr. Menghan Song, and Professor Zi Yang Meng from the Department of Physics at The University of Hong Kong (HKU) together with their collaborators Liuke Lyu and William WITCZAK-KREMPA from the University of Montreal has recently developed a novel algorithm in quantum physics known as ‘entanglement microscopy’ that enables visualization and mapping of this extraordinary phenomenon at a microscopic scale. Their study was published in a recent issue of Nature Communications. Using the algorithm, one can uncover the hidden structures of quantum matter, revealing insights that could transform technology and deepen the understanding of the universe. Continue reading

In this interview with HKU science editor, Dr Pavel Toropov, Professor Meng explains why AI is now indispensable in quantum physics research – by allowing us to circumvent the need for enormous computational complexity, AI can help to make breakthroughs and in the process help us to understand better of mother nature and ourselves. This leads to discoveries of quantum materials whose properties, such as superconductivity and entanglement, can change the world. The technology may be cutting edge, but the principles involved, says Prof Meng, go back to ancient greek maxim - know thyself, and the whole thing is similar to playing mahjong.
