QCommute: a tool for symbolic computation of nested commutators in quantum many-body spin-1/2 systems
Oleg Lychkovskiy, Viacheslav Khrushchev, Ilya Shirokov
QCommute is a C++ software tool that symbolically computes nested commutators between Hamiltonians and local observables for spin‑1/2 many‑body systems on hypercubic lattices, work…

Recursion method for quench dynamics: strengths and limitations
Ilya Shirokov, Viacheslav Khrushchev, Filipp Uskov +3
The recursion method, which solves coupled Heisenberg equations in a Lanczos operator basis, has recently emerged as a powerful nonperturbative tool for computing dynamical correla…
