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…
