Single-parameter spin-pumping in driven metallic rings with spin-orbit coupling
J. P. Ramos, L. E. F. Foa Torres, P. A. Orellana +1
We consider the generation of a pure spin-current at zero bias voltage with a single time-dependent potential. To such end we study a device made of a mesoscopic ring connected to…
Bound state in the continuum and spin filter in artificial molecules
J. P. Ramos, P. A. Orellana
In this paper we study the formation of bound states in the continuum in a quantum dot molecule coupled to leads. Based in the combination of bound states in the continuum and Fano…
Glassy phases and driven response of the phase-field-crystal model with random pinning
E. Granato, J. A. P. Ramos, C. V. Achim +4
We study the structural correlations and the nonlinear response to a driving force of a two-dimensional phase-field-crystal model with random pinning. The model provides an effecti…
Dynamical transitions and sliding friction of the phase-field-crystal model with pinning
J. A. P. Ramos, E. Granato, S. C. Ying +3
We study the nonlinear driven response and sliding friction behavior of the phase-field-crystal (PFC) model with pinning including both thermal fluctuations and inertial effects. T…
Nonlinear Driven Response of a Phase-Field Crystal in a Periodic Pinning Potential
C. V. Achim, J. A. P. Ramos, M. Karttunen +4
We study numerically the phase diagram and the response under a driving force of the phase field crystal model for pinned lattice systems introduced recently for both one and two d…
Thermal fluctuations and phase diagrams of the phase field crystal model with pinning
J. A. P. Ramos, E. Granato, C. V. Achim +3
We study the influence of thermal fluctuations in the phase diagram of a recently introduced two-dimensional phase field crystal model with an external pinning potential. The model…
