Nested Iterative Shift-invert Diagonalization for Many-body Localization in the Random-field Heisenberg Chain

Taito Kutsuzawa, Synge Todo

We study the many-body localization of the random-field Heisenberg chain using the nested shift-invert Lanczos method with an iterative linear solver. We use the minimum residual m…
