Brief Description 
The
subject materials that we have identified so far are not only the
hottest current research topics, more important, these are the areas
that our community have enough technical know how, expertise, and
insights to make major contributions. 

In Cosmology: 

To
investigate the detailed mechanisms of inflation from nonequilibrium
point of view(in particular, stochastic inflation) and compare with CMB
data and large scale structures of the universe; the origin of dark
matter within or beyond the Standard Model; the physics, properties,
and origin of dark energy. 
In General Relativity: 

Gravitational
energy, gravitational radiation reactions and quasinormal modes of
black holes which affect lots of topics in cosmology will be our main
activities. 
In Quantum Gravity: 

Canonical
quantization of gravity using Ashtekar variables, stochastic gravity
using closedtimepath techniques, and quantum to classical transitions
will be studied.

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. 
(1) 
2007 Tainan School and Workshop on
Cosmology and Gravitation at NCKU
(13th – 16th January, 2007): 

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
semiclassical 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.), BeiLok 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.



(2) 
2007 Taipei School/Workshop on Large
Scale Structures of the Universe(28th May
– 2nd June, 2007, NTNU): 

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:
LiZhi Fang( Dept. of Physics, University
of Arizona), Prof. Houjun Mo( Dept. of
Astronomy, Univ. of Massachusetts), Prof.
Yipeng Jing(Shanghai Astronomical
Observatory), Prof. LongLong Feng(Purple
Mountain Observatory)



(3) 
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 Nonequilibrium Dynamics and Quantum Coherence
Phenomena was aimed to provide the basic ideas and concepts of the
method of nonequilibrium theory including the FeynmanVernon 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.
