Collaborations & on-going project

To generate long-term collective force in Cosmology and Gravity be searched activities among the local communities and Asia Pacific areas;

Using non-equilibrium field theories and general relativity as keys to generate interdisciplinary and cutting-edge research activities on cosmology, classical and quantum gravity and quantum information science;

To train and create chances for talented graduate students and postdocs to make major contributions by helping them to identify hot and important interdisciplinary problems in the area of cosmology, gravitation and quantum gravity.

◎ The following major activities are carried out from last year to the future on top of our regular/irregular journal club meetings in Institute of Physics, Academia Sinica and Department of Physics, National Central University and shall be carry on in the next.

This was the first school/workshop in this field in Taiwan so far. The main purpose of this meeting is to introduce to students and researchers the latest developments in stochastic quantum gravity, cosmology and semi-classical quantum gravity. We have about 70 graduate students, postdocs and local faculities and faculties from Asia Pacific area in the meeting. Major lectures were delivered by researcher from overseas:L. Ford (Tufts U.), Bei-Lok Hu (Maryland U.), Misao Sasaki (Kyoto U.), Albert Roura(Los Alamos), E. Verdaguer (Universitat de Barcelona), Y. K. Lau (Inst. of Applied Math., Academica Sinica, Beijing), R. S. Tung (Shanghai Normal U.) Research topics in applying stochastic gravity to cosmology and black holes were carried out by D.S. Lee, K.W. Ng, W.L. Lee and H.T. Cho among group members immediately after the workshop and papers were also published (see publication list in the below) in these related areas.

Though the discovery of dark energy led us venturing into an uncharted territory, large piles of precise observational data and efficient numerical techniques have helped the study on the Universe continue to thrive in the 21st century.The purpose of this School/Workshop was to introduce students and faculties in Taiwan the progress and the state of the art in this fascinating frontier of physics and astronomy. The lectures were delivered by:
Li-Zhi Fang( Dept. of Physics, University of Arizona), Prof. Houjun Mo( Dept. of Astronomy, Univ. of Massachusetts), Prof. Yipeng Jing(Shanghai Astronomical Observatory), Prof. Long-Long Feng(Purple Mountain Observatory)

Collaborate with the Quantum Information Sciences focus group in running the Summer School on Nonequilibrium Dynamics and Quantum Coherence (4th – 6th July, 2007, NCKU)

This Summer School on Non-equilibrium Dynamics and Quantum Coherence Phenomena was aimed to provide the basic ideas and concepts of the method of nonequilibrium theory including the Feynman-Vernon and coherent state path integral formulation, and Schwinger- Keldysh's nonequilibrium Green's function method. The lecturers from our focus group members and visitors are: B. L. Hu and D. S. Lee.
We want to emphasize that our postdocs, C.S Chou's and S.Y. Lin's works on topics on Quantum Entanglement and Moving Atoms in Quantum Fields provide excellent examples on how interdisciplinary works between nonequilibrium field theories, general relativity and quantum information science can be combined coherently to achieve major breakthrough towards the understanding of these hot topics which have found important applications in quantum information science and the gravitational wave detecting LIGO physics.

Visiting prestigious academic institutes

With the help of Prof. L. Ford and B.L. Hu our postdocs (S.Y. Lin, C.S. Chou and C.H. Wu)were arranged to visit and conduct research at Princeton ‹‹- Highlights of Focus Group University, Univsersity of Maryland, Tuft University and International Center for Gravitation Research at University of Pennsylvania.

With the help of Prof. Y.K. Lau, 10 graduate students (from NCU, NDHU and NCKU) were arrange to attend the gravitation workshop at Institute of Applied Mathematics, Academia Sincia, Bejing during the summer.
