Núñez Vásquez, Álvaro; Fernández Rossier, J. (2010)We consider dilute magnetic doping in the surface of a three dimensional topological insulator where a two dimensional Dirac electron gas resides. We find that exchange coupling between magnetic atoms and the Dirac ...

Roldán Molina, A.; Santander, M. J.; Núñez Vásquez, Álvaro; Fernández Rossier, J. (American Physical Society, 2015)We study the quantum spin waves associated to skyrmion textures. We show that the zero-point energy associated to the quantum spin fluctuations of a noncollinear spin texture produce Casimir-like magnetic fields. We study ...

Roldán Molina, A.; Santander, M. J.; Núñez Vásquez, Álvaro; Fernández Rossier, J. (American Physical Society, 2014)We calculate the effect of spin waves on the properties of finite-size spin chains with a chiral spin ground state observed on biatomic Fe chains deposited on iridium(001). The system is described with a Heisenberg model ...
