Bosonization study of quantum phase transitions in the one-dimensional asymmetric Hubbard model
Bosonization study of quantum phase transitions in the one-dimensional asymmetric Hubbard model
The quantum phase transitions in the one-dimensional asymmetric Hubbard model are investigated with the bosonization approach. The conditions for the phase transition from density wave to phase separation, the correlation functions, and their exponents are obtained analytically. Our results show that the difference between the hopping integrals for up- and …
