CMSI International Satellite Meeting 2013 in Kobe＜終了＞

Aims and scope:

The tensor network algorithm is one of the most promising numerical methods for investigating quantum many-body systems in computational condensed-matter physics and quantum chemistry. In recent years, it has achieved a great progress with the help of quantum information theory and new matrix decomposition technique in computational science. The objective of this workshop is to offer a forum where concerned researchers can assemble and exchange information on the latest results and newly established methodologies, and discuss future directions of the interdisciplinary studies between the computational chemistry, physics, and mathematics, and the computer science.

This workshop is held as one of three satellite workshops of CMSI International Symposium 2013: Extending the power of computational materials sciences with K computer (Oct.21-22, Tokyo).

Topics:

• Tensor network based algorithms: MPS, DMRG, PEPS, MERA, and more.
• Application to strongly correlated systems in quantum chemistry and physics.
• Relation with quantum information, entanglement, etc.
• Numerical techniques: matrix diagonalization, higher-order SVD, etc
