Using Bogoliubov’s inequality we rigorously show that the multiorbital Hubbard model with narrow bands, even in the presence of spin–orbit coupling, does not exhibit long-range nematic order, in low dimensions. This result holds at any finite temperature for both repulsive and attractive Coulomb interactions, with and without spin–orbit coupling.

Abstract: | Using Bogoliubov’s inequality we rigorously show that the multiorbital Hubbard model with narrow bands, even in the presence of spin–orbit coupling, does not exhibit long-range nematic order, in low dimensions. This result holds at any finite temperature for both repulsive and attractive Coulomb interactions, with and without spin–orbit coupling. |
