Ellipticity effects on diffusive magnon spin and heat transport in easy-plane ferromagnets
Nicolas Vidal-Silva, Alejandro O. Leon
When a magnetic material hosts spin-wave excitations, or magnons, the local magnetization can rotate in circular or elliptical orbits, the latter arising naturally in the presence…
On the Meaning of the Web as an Object of Study
Claudio Gutierrez, Daniel Hernández
This text advances the hypothesis that the meaning of the Web as an object of study has diluted as a clear research domain. One example of this phenomenon is the identity crisis of…
A contact process with stronger mutations on trees
Fábio Lopes, Alejandro Roldán-Correa
We consider a spatial stochastic model for a pathogen population growing inside a host that attempts to eliminate the pathogens through its immune system. The pathogen population i…
Quasi-fluxon bubble dynamics in a rapid oscillatory microwave field
Alicia G. Castro-Montes, Elram S. Figueroa, Juan F. Marín +1
In this article, we numerically study the dynamics of a two-dimensional quasi-fluxon bubble in an oscillatory regime stabilized by a localized annular force under a rapidly oscilla…
A synchrotron-like pumped ring resonator for water waves
Isis Vivanco, Alexander Egli, Bruce Cartwright +2
The wave-like behaviour of matter in quantum physics has spurred insightful analogies between the dynamics of particles and waves in classical systems. In this study, drawing inspi…
Harnessing Interlayer Magnetic Coupling for Efficient, Field-Free Current-Induced Magnetization Switching in a Magnetic Insulator
Leran Wang, Alejandro O. Leon, Wenqing He +9
Owing to the unique features of low Gilbert damping, long spin-diffusion lengths and zero Ohmic losses, magnetic insulators are promising candidate materials for next-generation sp…
Evolving disorder and chaos enhances the wave speed of elastic waves
M. Ahumada, L. Trujillo, J. F. Marín
Static or frozen disorder, characterised by spatial heterogeneities, influences diverse complex systems, encompassing many-body systems, equilibrium and nonequilibrium states of ma…
Highly-enhanced propagation of long-range kinks in heterogeneous media
Jorge A. González, Alberto Bellorín, Luis E. Guerrero +2
We investigate a field-theoretical model that describes the interaction between kinks and antikinks and between kinks and other heterogeneous fields and impurities. We show that th…
Spin-orbit torque on nuclear spins exerted by a spin accumulation via hyperfine interactions
Adam B. Cahaya, Alejandro O. Leon, Mohammad H. Fauzi
Spin-transfer and spin-orbit torques allow controlling magnetic degrees of freedom in various materials and devices. However, while the transfer of angular momenta between electron…
Fluid motion for reducing the bounce of partially filled containers
Klebbert Andrade, Javiera Catalán, Juan F. Marín +4
Certain spatial distributions of water inside partially filled containers can significantly reduce the bounce of the container. In experiments with containers filled to a volume fr…
Dzyaloshinskii-Moriya spin density by skew scattering
Adam B. Cahaya, Alejandro O. Leon
Anisotropic exchange couplings, such as the Dzyaloshinskii-Moriya interaction (DMI), have played a vital role in the formation and dynamics of spin textures. This work predicts an…
Mixed-anion mixed-cation perovskite (FAPbI)(MAPbBr): an ab-initio molecular dynamics study
Eduardo Menéndez-Proupin, Shivani Grover, Ana L. Montero-Alejo +3
Mixed-anion mixed-cation perovskites with (FAPbI)(MAPbBr) composition have allowed record efficiencies in photovoltaic solar cells, but their atomic-scale behav…
Drift instabilities in localised Faraday patterns
Juan F. Marín, Rafael Riveros Ávila, Saliya Coulibaly +2
Nature is intrinsically heterogeneous, and remarkable phenomena can only be observed in the presence of intrinsically nonlinear heterogeneities. Spontaneous pattern formation in na…
Searching for changing-state AGNs in massive datasets -- I: applying deep learning and anomaly detection techniques to find AGNs with anomalous variability behaviours
P. Sánchez-Sáez, H. Lira, L. Martí +14
The classic classification scheme for Active Galactic Nuclei (AGNs) was recently challenged by the discovery of the so-called changing-state (changing-look) AGNs (CSAGNs). The phys…
Voltage-control of damping constant in magnetic-insulator/topological-insulator bilayers
Takahiro Chiba, Alejandro O. Leon, Takashi Komine
The magnetic damping constant is a critical parameter for magnetization dynamics and the efficiency of memory devices and magnon transport. Therefore, its manipulation by electric…

Osmel Martínez Rosabal, Onel L. Alcaraz López, Hirley Alves +2
Wireless energy transfer (WET) is emerging as an enabling green technology for Internet of Things (IoT) networks. WET allows the IoT devices to wirelessly recharge their batteries…
LoRa Performance Analysis with Superposed Signal Decoding
J. M. de Souza Sant'Ana, A. Hoeller, R. D. Souza +2
This paper considers the use of successive interference cancellation (SIC) to decode superposed signals in Long Range (LoRa) networks. We build over a known stochastic geometry mod…
