In the Physics Department of HKUST, both Professor Kwok Yip Szeto and Professor Michael Wong carry out research work on information physics. There are some frequent questions on this expanding area. You can find the answers provided by our scientists below:
Q: What is information physics? I am excited to see an old subject expanding into new areas!
A: Yes, in recent years, theoretical physics has expanded into new areas of the dynamic world which had never been envisaged a generation ago. Information physics is a fine example. It is a new area of research that connects physics with information theory.
Q: Can you give a few examples of the research areas?
A: Nonlinear dynamics, complex systems, econophysics, neural networks, and optimization algorithms are just a few examples that thrive on ideas from information physics.
Q: Well, these are areas which are usually studied by other disciplines. Where does the physics component come in?
A: This new development is blessed by advances in many-body physics and statistical physics in dealing with the collective properties of a large number of seemingly disordered entities. In fact, many information systems belong to this category and the techniques of many-body physics and statistical physics are often useful.
Q: What topics are the physicists in HKUST working on?
A: In HKUST, physicists have devoted considerable effort in the studies of complex information systems which include the following topics: information processing and retrieval, intelligent control, optimization of networks, error-correcting codes, agent dynamics, artificial life, evolution theory, parallel genetic algorithm, and DNA sequence analysis.
