Role of four-fermion interaction and impurity in the states of two-dimensional semi-Dirac materials.
We study the effects of four-fermion interaction and impurity on the low-energy states
of two-dimensional semi-Dirac materials by virtue of the unbiased renormalization group
approach. The coupled flow equations that govern the energy-dependent evolutions of all
correlated interaction parameters are derived after taking into account
one-loop corrections from the interplay between four-fermion interaction and impurity.
Whether and how four-fermion interaction and impurity influence the low-energy properties
of two-dimensional semi-Dirac materials are discreetly explored and addressed attentively.
After carrying out the standard renormalization group analysis, we find that both trivial
insulating and nontrivial semimetal states are qualitatively stable against
all four kinds of four-fermion interactions. However, while switching on both four-fermion
interaction and impurity, certain insulator-semimetal phase transition and the distance of
Dirac nodal points can be respectively induced and modified due to their strong interplay
and intimate competition. Moreover, several non-Fermi liquid behaviors that deviate from
the conventional Fermi liquids are exhibited at the lowest-energy limit.
