[Japanese・English]

Tensor network formulation of many-body systems are widely used in various research fields of sciences, bringing theoretical and numerical approaches from a different perspective from the conventional ones. Recently, tensor network-based ideas are also rapidly gaining popularity in the fields such as quantum algorithms, quantum computation, and machine learning. The aim of this workshop is to provide a broad overview of the recent progress based on tensor network formalism, mainly in the fields of particle, nuclear, and condensed matter physics, to encourage the exchange of information among different communities, and to stimulate new developments in the field of tensor networks.
