Jinshan's homepage at BNU
I am a professor of physics and systems science in the School of Systems Science at Beijing Normal University. Currently I am working in quantum transport, game theory, scientometrics, general input-output analysis, Chinese characters and more general learning theory (The latter three might be seen as applications of network science to problem solving in various disciplines).
Supervising actively graduate students and post-docs.

Research Interests and miscellaneous ideas
Physics is all about interactions. It is also interaction that makes the world diverse (instead of homogeneous), beautiful and worth studying. Statistical physics starts from theories and their related computational techniques for collections of non-interacting units (thus non-interacting systems) and then moves to dealing with interacting systems, where one unit of the system is connected to others. Dealing with such interactions at microscopic level is called mechanics (we have classical and quantum mechanics), while dealing with such interactions at macroscopic level, sometimes phenomenologically, is called thermodynamics, and here comes the statistical mechanics or statistical physics when asking for the bridge between the micro and the macro level.
First major theme that I am working on is theoretical and computational foundations of statistical physics: why the Boltzmann distribution is valid for equilibrium statistical systems and what is the correspondence for non-equilibrium but still stationary systems, especially when the system has quantum nature and is interacting?
Second, beyond physics objects, there are other interacting systems, can the theories and computational techniques from statistical physics be applied to them, such as interactions among rational (full or partial) and intellectual agencies. This is where I started to look into game theory, a theory about agencies, which are quite often human being, with conflicting interests.
There are other more general interacting systems too, such as a collection of Chinese characters (they are different from a collection of light bulbs), a set of research papers, a set of all kinds of industrial products, a set of science concepts. This drives me into the third topic that I am actively working on now and hopefully for the future: network science and its application to (also back action from) scientometrics, knowledge management, meaningful learning and input-output analysis.
Sometimes, my thoughts get stuck in foundations of quantum mechanics too. It is such a fascinating field and it drives me into excited states all the time.
I enjoy reading and working on creative questions which also have fundamental importance -- those might improve our understanding of the world, natural or social. I like those even more if results/methods developed from those investigations have some practical potential.
Here are the more detailed description of each topic.
- Quantum Transport (projects overview, started from my PH.D. project with Mona Berciu at phas@UBC)
- Game Theory and Quantum Game (projects overview)
- A theory of games that can be used to compare with real observations and experiments, the Ultimatum game as an example, currently working on, together with Nick Vriend from Queen Mary University of London, Keqiang Li, Ya Zhou, Liujun Chen, Zengru Di from School of Systems Science at BNU

- a brief history of Quantum Game
- A general proof of the existence of NE in quantum game in the operator representation (not started yet)
- Let a quantum entangle system to be the game object(not started yet)
- Could the state of players be an entangle state? Entangle between players, not objects (not started yet)

- The correlation between editorial delay and number of recieved citations (a link to the published paper)
- Do scientists, in math, physics, life science and economics, trace hot topics?, published by Scientific Reports here and highlighted by Nature here
- Do mathematicians, economists and biomedical scientists trace large topics more strongly than physicists?, published by Journal of Informetrics here
- Network of Chinese characters and its implication to teaching and learning of Chinese characters, published by PLOS ONE here, covered by a BBC story here
- Complex Networks(projects overview)
- Quantum foundation: Validity of Hidden variable theory(PDF, together with Prof. Shouyong Pei)
- Econophysics (projects and a review paper, together with Yougui Wang and Zengru Di)
- Miscellaneous ( ^_^, no review and no projects, just idea, let me wish they will become projects one day )
- Structural Chinese: Chinese is a language with many structures at all levels, from radicals to Chinese characters and from characters to words. We may discover them through the network analysis and make use of them in teaching Chinese via designing better textbooks.
- Times Series Analysis of Music: Times series analysis of sounds and songs gives us pitches and notes, what we can see from a time series analysis of those sequences of pitches?
- Thinking in Universal Language: Computers speak machine-dependent binary languages. But they communicate and we communicate with them too via high-level programming languages. Human being speaks different languages and every individual thinks in its own languages, which sometimes appears to be its native language. Thinking in its own does not pick up which language to use, but most time it relies on certain languages. This seems very much like the relation between the abstract vectors in Hilbert space and their explicit representations whenever we write them down to manipulate them. So could human being think and communicate via a common language, the one corresponding to the abstract vectors, not any representations? If possible, what are the features of such common language, which carries thoughts directly not via any social languages?

Selected articles from Jinshan's Blog（in Chinese）
If you are interested in any of those not-yet-started projects and you think you might proceed faster than me, I am happy to share my thoughts.
If you are looking for a PH.D., a post-doc position, or even a faculty position in physics (with specialty in quantum transport, statistical physics), systems science (with specialty in game theory, scientometrics, natural language processing, input-output analysis) or mathematics (with specialty in numerical linear algebra, stochastic process), please send me an email or visit this web page.
