Symmetry breaking and spectral structure of the interacting Hatano-Nelson model
We study the Hatano-Nelson model, ie, a one-dimensional non-Hermitian chain of spinless
fermions with nearest-neighbor nonreciprocal hop**, in the presence of repulsive nearest …

Perspective on topological states of non-Hermitian lattices
LEFF Torres - Journal of Physics: Materials, 2019 - iopscience.iop.org
The search of topological states in non-Hermitian systems has gained a strong momentum
over the last two years climbing to the level of an emergent research front. In this perspective …

Edge states in a non-Hermitian chiral lattice
Non-Hermiticity can alter the topological properties of energy bands and drive topologically
trivial systems with Hermitian limits to generate nontrivial topological edge states …

Nonorientability-induced phase transition in ladder lattices
We study parity-time (PT) phase transitions in the energy spectra of ladder lattices caused by
the interplay between nonorientability and non-Hermitian PT symmetry. The energy spectra …
