Adaptive Pseudoboson Density-Matrix Renormalization Group for Dilute 2D Systems
Fabian J. Pauw, Thomas Köhler, Ulrich Schollwöck +1
Simulating strongly correlated systems in two dimensions is notoriously challenging due to rapid entanglement growth and frustration. Here, we introduce the adaptive projected-puri…

Matrix-product-state-based band-Lanczos solver for quantum cluster approaches
Sebastian Paeckel, Thomas Köhler, Salvatore R. Manmana +1
We present matrix-product state (MPS) based band Lanczos method as solver for quantum cluster methods such as the variational cluster approximation. While a naïve implementation o…
