Galois Solvability of Finite-Size Bethe Solutions in the Heisenberg Chain
Oliver R. Bellwood, William J. Munro
The spin-1/2 Heisenberg antiferromagnetic chain is the canonical example of an integrable quantum many-body model. Despite its exact solvability, explicit finite-size solutions are…

Fractal Path Strategies for Efficient 2D DMRG Simulations
Oliver R. Bellwood, Heitor P. Casagrande, William J. Munro
Numerical simulations of quantum magnetism in two spatial dimensions are often constrained by the area law of entanglement entropy, which heavily limits the accessible system sizes…
