Tensor network methods are rapidly developing and evolving in many areas of quantum physics. They offer new ways of computing the properties of strongly interacting quantum matter. They provide new perspectives on theories with sign problems and/or significant entanglement. Tensor network ideas are also closely related to emerging efforts to design algorithms suitable for current and future quantum computing hardware or quantum simulation experiments. This workshop will bring together experts from a range of scientific fields with a common interest in these new methods.


Goals of the program

The aim of the workshop is to promote an exchange of ideas concerning tensor networks between different groups of theorists working in particle, nuclear and condensed matter physics. They share interests in developing efficient numerical algorithms based on tensor networks that allow for the accurate calculation of physical properties. We expect the workshop will help foster the exchange of ideas that will be beneficial for each group.

Despite the differences in the physics goals of the various practitioners, the concepts of universality and emergent symmetries provide a unified framework to understand the critical behavior of a variety of physical systems. We expect that the exchange of ideas will help in adapting these methods to systems in higher dimensions with more complex symmetries, both global and local.

Recasting quantum field theories in the language of tensor networks can lead to new insights both on the nature of quantum entanglement and the holographic principle. The latter connection is particularly exciting as it has potential to provide insights into the nature of quantum black holes and quantum gravity.



This workshop is an extension of the previous online program held in May-June 2021 and will consist of a further week of in-person talks and discussions. The workshop will be comprised of four 1-hour invited talks per day together with ample time for discussions. 


Note: There will be a $70 registration fee to attend this workshop. The registration fee includes participation in the workshop, lectures, and coffee breaks.
