Real-time evolution in the Hubbard model with infinite repulsion
Real-time evolution in the Hubbard model with infinite repulsion
We consider the real-time evolution of the Hubbard model in the limit of infinite coupling. In this limit the Hamiltonian of the system is mapped into a number-conserving quadratic form of spinless fermions, i.e. the tight binding model. The relevant local observables, however, do not transform well under this mapping …
