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…

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…

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…
