Abstract
We compute ground state fidelity of the one-dimensional Bose-Hubbard model at unit filling factor. To this aim, we apply the DMRG algorithm to systems with open and periodic boundary conditions. We find that fidelity differs significantly in the two cases and study its scaling properties in the quantum critical regime.
Why This Paper Matters
- It adds a 2013 reference point for readers tracking recent quantum research.
- We compute ground state fidelity of the one-dimensional Bose-Hubbard model at unit filling factor.
