ITensor School

  • Organized by
  • Miles Stoudenmire, Ph.D.Research Scientist, CCQ, Flatiron Institute
  • Matthew FishmanAssociate Data Scientist, CCQ, Flatiron Institute
Date & Time


162 5th Avenue, 7th Floor Classroom

Deadline to Register

Friday January 17, 2020

Invitation Only

Participation is by invitation only. All participants must register.

The ITensor library is a powerful tool for tensor network computations. The goal of the ITensor School is to both introduce new ITensor users to the software and its applications, and help more experienced users undertake challenging new projects. The school will include lectures and hands-on tutorials by ITensor developers Matt Fishman, Miles Stoudenmire, and Steve White (the inventor of DMRG). There will also be free time for attendees to work on their code and have discussions.

The lectures and tutorials will be conducted in the Julia programming language, using the upcoming Julia version of ITensor. However, attendees interested in or already using the C++ version are certainly welcome to conduct their projects in that version and ask us questions about it. No prior experience with Julia or C++ is required, though attendees are strongly encouraged to practice using Julia before the school.
