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.

Here are my CV (in doc and pdf format) and a list of publications,

and their Chinese versions: 简历 (in doc and pdf format) and 期刊论文。

Or you may take a look at the Chinese version (中文版) of this website: 吴金闪在北京师范大学的主页.

Research Interests and miscellaneous ideas

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.

Recently, inspired and developed from our previous studies on applications of network science, or big physics, or systems science, to scientometrics, knowledge management, meaningful learning, and input-output analysis, we have established the Institute of Educational System Science (IESS) to work a new model of education and also a new model of scientometrics. Please visit the IESS website for more details.

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.

• 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?
