The Two Orbital, Interacting Hatano-Nelson Model

Jonah Huang, Nancy Aggarwal, Richard Scalettar, Rubem Mondaini

The interacting two-orbital Hatano-Nelson model admits regions of parameter space where the full spectrum is real, set by interaction strength, hopping asymmetry, and interchain coupling.

Claims

C1strongest claim

Our key results are to obtain the phase diagrams for the existence of a purely real spectrum, as a function of the interaction strength, degree of non-Hermiticity, and interchain hopping. ... we solve the dynamics at low filling according to Lindbladian evolution and find that the non-Hermitian description is able to qualitatively describe such systems.

C2weakest assumption

The non-Hermitian effective Hamiltonian qualitatively captures the Lindbladian evolution at low filling, and finite-lattice spectral properties generalize to the thermodynamic limit without additional boundary or finite-size artifacts.

C3one line summary

In the two-orbital interacting Hatano-Nelson model, phase diagrams show regimes of purely real spectra controlled by interaction strength, non-Hermiticity, and interchain hopping, with links to skin modes and qualitative Lindbladian dynamics.
