Accomodation Program Organizing Committee  

The 1st international symposium on Clustering as a window on the hierarchical structure of quantum systems (CLUSHIQ2020) will be held in Beppu in Kyushu island, Japan, from Jan. 23-24, 2020.

This symposium is aiming at discussing why our material world has a hierarchical structure: quarks, hadrons, nuclei, atoms and molecules. In particular, we focus on clusters and strong correlations in each hierarchy, which may provide us keys to understand the hierarchical structure in universal way. We also discuss the characteristic feature of correlations/clustering in each hierarchy.

The topics include:

  1. Exotic hadrons using high-energy heavy-ion collisions, pp collisions and other reactions
  2. Lattice QCD, Ab-initio calculations
  3. Exotic nuclei, alpha clusters, multi-neutron clusters, NN correlation
  4. Three nucleon force, many-body force
  5. Hypernuclei, strangeness, hyperon-nucleon interactions
  6. Ultra-cold atoms and exotic atomic/molecular states/phases, quantum simulation
  7. Efimov physics
  8. Few-body physics

This symposium is organized by Grant-in-Aid for Scientific Research on Innovative Areas, “Clustering as a window on the hierarchical structure of quantum systems”
(MEXT Kakenhi 18H05400)


CLUSHIQ2020 will take place at Beppu city in Kyushu Island, Japan. Beppu is famous for Onsen (Hot-spring Spa). Indeed, Beppu has the largest number of hot-spring sources in Japan. You can see clouds of steam everywhere in the city. The city is well connected to major cities in Japan by air and by trains. The city is about 45min bus ride from the nearest airport “Oita Airport”, which has more than 10 flights/day from/to Haneda airport in Tokyo, which is now connected to major cities in the world. The nearest station “Beppu” is about 2 hour train ride from Hakata station in Fukuoka. See the detail in “Transportation”.

The venue is Spa & Resort Ryotiku Bettei in Beppu city. (Japanese) (English)
All the participants are expected to stay here for 22nd-24th.

Deadline; November 30th, 2019
*Applicants to travel support will be notified on the results of their applications latest by 10th December 2019.

Fees: 11,000 JPY
The registration fee includes refreshments throughout the conference, lunch on Thursday and Friday and dinner on Thursday. The fee does not include accommodation. Please refer to the “Accommodation


 <<To Beppu>>
There are mainly two routes:
1) Via Oita airport: This airport is closest to the conference venue, and is frequently connected to Tokyo-Haneda, and Osaka-Itami airport. The best way from abroad is to reach Tokyo Haneda.  If you reach Tokyo-Narita airport instead, then take a train or Limousine bus to Tokyo Haneda which takes about 1~1.5 hours.

From Oita Airport to Beppu Station
Take an Airport Express Airliner from Oita airport to Beppu Station. It takes about 45 min., and costs 1,500 Yen.

From Beppu station to Conference Venue:  See below

2) Via Fukuoka airport: This airport is about 2 hours away from Beppu city, but the flights are even more frequent to Tokyo Haneda/Osaka Itami, and other domestic cities. This airport has also some international connections.

・From Fukuoka Airport/Hakata Station to Beppu Station

2)-i)BUS: Take an Express bus from Fukuoka Airport or from Hakata Bus Terminal (Toyonokuni Bus). It takes about 2 hours and 15 minutes. Reservation is required in advance.  

2)-ii)TRAIN: Take a subway to Hakata station, then transfer to JR line from Hakata station to Beppu station(Limited Express SONIC). It takes about 2 hours.
Time tables for Limited Express SONIC:

 <<From Beppu to Conference Venue>>
・Take a free shuttle bus offered by the Hotel (Ryotiku Bettei, Symposium venue) from Beppu Station.  The reservation is required. So we will ask your arrival time by Jan.9th, 2020.
Time tables for the shuttle bus to Hotel as below;
Jan. 22th, 23rd.; 14:30,15:00,15:30,16:00,16:30,17:00,17:30,18:00

 ・Taking the taxi from Beppu station.

 <<Departing from the Conference Venue>>
 ・From Hotel to Oita Airport
We have reserved a shuttle bus to Oita Airport, which starts just after the end of the symposium at 15:30.  We will ask you if you would like to use this shuttle by Jan.9th, 2020.

   ・From Hotel to Beppu Station
 A shuttle bus to Beppu station is also available.
 We will ask you if you would like to use this shuttle by Jan.9th, 2020.
