      We study the spin waves of the triangular skyrmion crystal that emerges in a two-dimensional spin lattice model as a result of the competition between Heisenberg exchange, Dzyalonshinkii-Moriya interactions, Zeeman coupling ...
    • Topological states of non-Hermitian systems 
      Martinez Alvarez, V.; Barrios-Vargas, J.; Berdakin, M.; Foa Torres, L. (Springer Verlag, 2018)
      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. Lattices modeled through non-Hermitian Hamiltonians ...
    • Topological transitions in an oscillatory driven liquid crystal cell
