    • Asenjo Andrews, Daniel Arthur (Universidad de Chile, 2009)
      Se estudió un sistema de 3,6864×104 partículas que interactúan a través del potencial de Lennard-Jones mediante dinámica molecular, usando un código paralelo que integra las ecuaciones de movimiento diseñadas para simular ...
    • Ulloa, Camilo; Núñez Vásquez, Álvaro (Amer Physical Soc, 2016)
      We show that proper control of magnetization textures can be achieved in noncollinear antiferromagnets. This opens the versatile toolbox of domain-wall manipulation in the context of a different family of materials. In ...
    • González, A. L.; Landeros, P.; Núñez Vásquez, Álvaro (ELSEVIER, 2010)
    • Elías, R. G.; Carvalho-Santos, V. L.; Núñez Vásquez, Álvaro; Verga, A. D. (American Physical Society, 2014)
      © 2014 American Physical Society. We show that, after a transformation, the dynamics of linear perturbations (spin waves) around a singular Bloch point soliton is formally equivalent to a quantum system of an electron in ...
    • Gallardo, R. A.; Schneider, T.; Roldán-Molina, A.; Langer, M.; Núñez Vásquez, Álvaro; Lenz, K.; Lindner, J.; Landeros, P. (American Physical Society, 2018-05)
      Symmetry and localization properties of defect modes of a one-dimensional bicomponent magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a periodic array of nanostripes, where stripes ...
    • Giri, Santanab; Inostroza-Rivera, Ricardo; Herrera, Bárbara; Núñez Vásquez, Álvaro; Lund Plantat, Fernando; Toro Labbé, Alejandro (Springer Verlag, 2014)
      © 2014, Springer-Verlag Berlin Heidelberg.The mechanism of Menshutkin reaction, NH3 + CH3Cl = [CH3–NH3]+ + Cl-, has been thoroughly studied in both gas and solvent (H2O and cyclohexane) phase. It has been found that solvents ...
    • Troncoso Coña, Roberto Enrique; Núñez Vásquez, Álvaro (American Physical Society, 2014)
      We study the behavior of skyrmions in thin films under the action of stochastic torques arising from thermal fluctuations. We find that the Brownian motion of skyrmions is described by a stochastic Thiele’s equation ...
    • Aguilera, Esteban; Jaeschke Ubiergo, R.; Vidal Silva, N.; Foa Torres, Luis; Núñez Vásquez, Álvaro (Amer Physical Soc, 2020)
      We report on the magnon spectrum of Kitaev-Heisenberg magnets and extract the parameters to model a two-dimensional CrI3. Our minimal spin Hamiltonian includes a contribution stemming from a Heisenberg, isotropic exchange, ...
    • Roldán Molina, A.; Núñez Vásquez, Álvaro; Fernández Rossier, J. (IOP, 2016)
      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 ...
