QCommute is a new C++ tool for algebraic symbolic computation of nested commutators in quantum spin-1/2 many-body systems on hypercubic lattices in the thermodynamic limit.
Numerical simulations of the triangular Majorana-Hubbard ladder reveal multiple symmetry-protected topological phases identified through entanglement spectrum degeneracies and adiabatic connections.
In the Bose-Hubbard model, density correlation fronts propagate ballistically for all interaction strengths, while the correlation transport distance shows sub-ballistic growth in the chaotic phase due to distance-dependent long-time tails and enhanced front decay.

Dynamical Behaviour of Density Correlations Across the Chaotic Phase for Interacting Bosons
In the Bose-Hubbard model, density correlation fronts propagate ballistically for all interaction strengths, while the correlation transport distance shows sub-ballistic growth in the chaotic phase due to distance-dependent long-time tails and enhanced front decay.
