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…

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…
