Topological states of non-Hermitian systems

V. M. Martinez Alvarez, J. E. Barrios Vargas, M. Berdakin +1

Recently, the search for topological states of matter has turned to non-Hermitian systems, which exhibit a rich variety of unique properties without Hermitian counterparts. Lattice…

Lieb and hole-doped ferrimagnetism, spiral, resonating valence-bond states, and phase separation in large-U $A B_{2}$ Hubbard chains

V. M. Martinez Alvarez, M. D. Coutinho-Filho

The ground state (GS) properties of the quasi-one-dimensional $A B_{2}$ Hubbard model are investigated taking the effects of charge and spin quantum fluctuations on equal footing. In…
