Izvirni znanstveni članek
Oznake: Hubbard model;Hilbert-space fragmentation;spin transport;strongly correlated electrons;
The t model represents the Hubbard model in the limit U →∞and is one of the basic models of stronglycorrelated electrons. On a one-dimensional chain, the model is integrable, and its charge dynamics is equivalentto that of free spinless fermions. However, within its dynamics the sequence of spins is ...
