# Institute of Modern Physics

**Introduction of the Institute of Modern Physics**

The Institute of Modern Physics （IMP） in Northwest University was established through the initiative of Professor Bo-Yu Hou, who was also the first director of the Institute. In 1984, the institute, approved by Shaanxi Municipal Comission of Education, was officially founded, and later was appointed as one of the first post-doctoral research stations over China in 1985.

As a professional institute focusing its research emphasis on modern physics, the main research area of IMP members includes: mathematical physics; quantum integrable systems and low-dimensional condensed matter physics; gravity and string theory; quantum information and quantum computation; computational physics and simulation physics; atom-molecule physics, etc.

Due to the two generations’ effort, IMP has established an active and competitive research team, and published more than 520 papers (more than 60% papers in SCI). There are 10 faculty members aged from 35 to 65, and most of them have performed high quality, original research works on various fields, such as quantum field theory; classical and quantum anomalies in gauge theories; classical and quantum integrable systems; quantum groups and quantum algebras; quantum information, etc. Until now IMP have obtained many awards respectively, like the National Award of Natural Science of China (second and third classes) , the Award of Progress of Science and Technology of National Education Commission (first class), the Award of National Scientific Conference, the Award of Progress of Science and Technology of Shaanxi (first class) and so on.

Ever since its founding, 34 students have obtained their Ph.D degrees from IMP. Most of them have play key roles in various research fields and become academic leaders. Some of them have obtained many awards, include Alexander von Humboldt Fellowship (6 person-time); Japan Society for the Promotion of Science Invitation Fellowship (4 person-time); the program of “One Hundred Talented People”of the Chinese Academy of Science (1 person-time); Queen Elizabeth II Fellowship (1 person-time)
