Effect of phonons on the electron spin resonance absorption spectrum
(IOP Publishing Ltd., 2020-07)
The unavoidable presence of vibrations in solid-state devices can drastically modify the expected electron spin resonance (ESR) absorption spectrum in magnetically active systems. In this work, we model the effect of phonons ...
Coding closed and open quantum systems in MATLAB: applications in quantum optics and condensed matter
(IOP PUBLISHING LTD, 2020-07)
We develop a package of numerical simulations implemented in MATLAB to solve complex many-body quantum systems. We focus on widely used examples that include the calculation of the magnetization dynamics for the closed and ...
Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
(Chile. Universidad Mayor, 2020)
The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ...
Towards an analytical description of active microswimmers in clean and in surfactant-covered drops
(Chile. Universidad Mayor, 2020)
Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow. Based on a far-field analytical model, ...
From the open generalized Heisenberg model to the Landau-Lifshitz equation
(IOP Publishing Ltd., 2020-10)
Magnetic systems can be described by the classical Landau-Lifshitz (LL) equation or the fully quantum open generalized Heisenberg model. Using the Lindblad master equation and the mean-field approximation, we demonstrate ...
Enhancement of the spin-wave nonreciprocity in antiferromagnetically coupled multilayers with dipolar and interfacial Dzyaloshinskii-Moriya interactions
(American Physical Society, 2020-11)
Spin-wave-based circuits and logic devices have been considered as an alternative to current electronic devices as they approach the physical limit of miniaturization. Asymmetrical propagation of spin waves, also known as ...
Phase space classification of an Ising cellular automaton: The Q2R model
(Elsevier Ltd., 2020-04)
An exact classification of the different dynamical behaviors that exhibits the phase space of a reversible and conservative cellular automaton, the so-called Q2R model, is shown in this paper. Q2R is a cellular automaton ...
Highly porous tungsten for plasma-facing applications in nuclear fusion power plants: a computational analysis of hollow nanoparticles
(IOP Publishing Ltd., 2020-09)
Plasma-facing materials (PFMs) for nuclear fusion, either in inertial confinement fusion (ICF) or in magnetic confinement fusion (MCF) approaches, must withstand extremely hostile irradiation conditions. Mitigation strategies ...
Understanding contagion dynamics through microscopic processes in active Brownian particles
(Nature Publishing Group, 2020-11)
Together with the universally recognized SIR model, several approaches have been employed to understand the contagion dynamics of interacting particles. Here, Active Brownian particles (ABP) are introduced to model the ...
Thermal Stability of Hollow Porous Gold Nanoparticles: A Molecular Dynamics Study
(American Chemical Society, 2020-12)
Hollow nanoparticle structures play a major role in nanotechnology and nanoscience since their surface to volume ratio is significantly larger than that of filled ones. While porous hollow nanoparticles offer a significant ...
