Sublattice Coding Algorithm and Distributed Memory Parallelization for Large-Scale Exact Diagonalizations of Quantum Many-Body Systems
Alexander Wietek, Andreas M. Läuchli
We present algorithmic improvements for fast and memory-efficient use of discrete spatial symmetries in Exact Diagonalization computations of quantum many-body systems. These techn…
Finite Correlation Length Scaling in Lorentz-Invariant Gapless iPEPS Wave Functions
Michael Rader, Andreas M. Läuchli
It is an open question how well tensor network states in the form of an infinite projected entangled pair states (iPEPS) tensor network can approximate gapless quantum states of ma…
Unified Phase Diagram of Antiferromagnetic SU(N) Spin Ladders
Andreas Weichselbaum, Sylvain Capponi, Philippe Lecheminant +2
Motivated by near-term experiments with ultracold alkaline-earth atoms confined to optical lattices, we establish numerically and analytically the phase diagram of two-leg SU()…
