A Topological Magnonic Black-White Hole Crystal
D. Galvez-Poblete, R. M. Otxoa, A. S. Nunez +1
The low-energy dynamics of antiferromagnetic spin waves map onto a massive Klein-Gordon scalar field, providing a solid-state platform for analogue-horizon physics. We show that an…
Electrically Switchable Spintronics in a Multiferroic Altermagnet
Martin Latorre, Sebastian Allende, Alvaro S. Nunez
We introduce a minimal model of a two-dimensional lattice that, upon spontaneous symmetry breaking, simultaneously develops altermagnetic order, a finite electric polarization, and…
Moving Analogue Horizons in Stationary Ferroelectrics
David Galvez-Poblete, Rubén M. Otxoa, Alvaro S. Nunez +1
We show that a traveling modulation of the polarization-gradient stiffness in a ferroelectric material induces an effective flow in its collective polarization dynamics. Within a c…
A spin-bond theory unifying non-relativistic spin splitting and emergent spin-orbit textures
S. Allende, R. M. Otxoa
Magnetic order with vanishing net magnetization can produce non-relativistic spin-split bands, broadly categorized into even-parity altermagnets and odd-parity \(p\)-wave magnets.…
Magnetic texture modulated superconductivity in superconductor/ferromagnet shells of semiconductor nanowires
Nabhanila Nandi, Juan Carlos Estrada Saldaña, Alexandros Vekris +11
In a one-dimensional ferromagnet-superconductor nanowire, magnetism can suppress superconductivity except where the Zeeman field is suppressed, for example domain wall superconduct…
Vacuum-selected timescales in driven Josephson systems
Sebastian Allende, David Galvez-Poblete
In this work, we demonstrate that the intrinsic timescale of a Josephson junction can be controlled through dynamical vacuum selection. By applying a Kapitza-like high-frequency dr…
Elastic Dislocation-based Skyrmion Traps: Fundamentals and Applications
Martín Latorre, Joaquín Barra, Juan Pablo Vera +4
Topologically secure spin configurations, such as skyrmions and bimerons, offer a compelling alternative to conventional magnetic domains, potentially enabling high-density, low-po…
Magnetic Worms: Oscillatory Bimeron Pairing And Collective Transport In Patterned Stripes
Jose Toledo-Marin, Mario Castro, David Galvez-Poblete +4
Magnetic bimerons in a domain wall provide a practical route for current driven transport in patterned magnetic stripes. However, coupling between bimerons and pinning by defects c…
On the Electronic Contribution to Crystalline Diffraction Patterns
Sebastian Allende, David Galvez-Poblete
We introduce the electronic structure factor as a phase-sensitive contribution to diffraction that directly encodes the properties of the occupied-band wave functions. In the one-d…
Electric-Field Control of Josephson Oscillations in Dipolar Bose-Einstein Condensates
David Galvez-Poblete, Roberto E. Troncoso, Guillermo Romero +2
We study the dynamic behavior of a Bose-Einstein condensate (BEC) with dipolar interactions when the influence of external electric fields affects the coherent tunneling properties…
Antiferron Modes in Ferroelectric Materials
David Galvez-Poblete, Mario A. Castro, Roberto E. Troncoso +3
We introduce the concept of antiferron modes in ferroelectric materials as dynamically stabilized collective excitations over inverted polarization states that decrease the system…
Elementary theory of Magnetoferrons: bringing magnons and ferrons together in multiferroic systems
Mario Castro, Carlos Saji, Guidobeth Saez +3
The collective excitations of a multiferroic material are analyzed. We show that these excitations also exhibit magnetoelectric behavior, leading to the hybridization of magnons ,o…
Magnonics along the wall in Bimeron Chain Domain Walls
Carlos Saji, Eduardo Saavedra, Roberto E. Troncoso +3
We demonstrate that domain walls built from bimeron chains (bc-DW) in two-dimensional systems constitute a spontaneously assembled medium that holds magnonic excitations along its…
Bimerons as Edge states in Thin Magnetic Strips
Mario Castro, David Gálvez, Sebastián Castillo +3
Magnetic bimerons are potential information carriers in spintronic devices. Bimerons, topologically equivalent to skyrmions, manifest in chiral magnetic systems with in-plane magne…
Chiral spin-transfer torque induced by curvature gradient
G. H. R. Bittencourt, M. Castro, A. S. Nunez +3
This work analyzes the propagation of a transverse domain wall (DW) motion under the action of an electric current along a nanowire (NW) with a curvature gradient. Our results evid…
