  • Jan 22, 2020: Introduction
  • January 25, 2020: Manipulating Tensor Networks
  • January 29, 2020: Advanced Manipulations
    • Reading for today: arXiv:1306.2164 -- page 15-18
    • Other preparation: Bring laptop with Mathematica
      • Please complete the notebook: TensorIntro2.nb -- that we did not have time to do last day.
      • Please download the following notebook: TensorIntro3.nb -- and have it queued up on your computer.
    • Lecture Notes: Chapter 3
    • Homework 3 (in lecture notes): Due Feb 5. 
  • January 31, 2020: Canonical Forms
  • February 5, 2020: Optimizing Matrix Product States -- iDMRG 
    • Reading for today: Schollwock, arXiv:1008.3477 p. 6-11
    • Other preparation: Bring laptop with Mathematica
      • Please download the following notebooks: MinimalNamedTensors.nb and SInfiniteDMRG_Empty.nb . Put them both in one directory, then open SInfiniteDMRG_Empty.nb. It has a skeleton for our DMRG code.
      • A running version the code is SInfiniteDMRG.nb, in case you get stuck -- but I recommend that you don't look at this unless you have to.
    • Lecture Notes: Lecture Notes: Chapter 5
    • Homework 5 (in lecture notes): Due Feb 12. 
  • February 7, 2020: Finite DMRG, conserved quantities, and further tricks
