OpenMX/QMAS workshop 2008

Program

The 1st and 2nd days will be devoted to disucuss methodological aspects of the codes and its applications, respectively. A hand-on course for applicants will be held in the morning of the 3rd day. Applicants who let us know in the registration will be able to stay in seminar rooms on the 8F of the material science buliding IV in JAIST till the 25th April for further discussions.

The time table of bus connecting JAIST and hotels is now available at here.

The program of the poster session is available at here.

For discussion seven minutes will be allocated in each talk.

The 1st day (21th April)

The 3rd day (23th April)
at the 8 floor of the material science building IV:

There are two sessions in the Wednesday morning. One of them is the hand-on course on OpenMX and QMAS codes for applicants. The other consists of a series of informal seminars including first-principle calculations of strongly correlated systems. The participants may attend one of them.

The hand-on course for applicants (Room: M4-85)

The participants in the hand-on course are expected to bring your own laptop computer with a linux or cygwin environment. Since we will not provide machines available in JAIST, we would expect that you are able to access a machine in your laboratory via the network.
