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…
Magnetic topological textures in nonorientable surfaces
Carlos Saji, Mario A. Castro, Vagson L. Carvalho-Santos +3
Topological magnetic textures confined to two-dimensional (2D) non-orientable manifolds exhibit behaviors absent in planar systems. We investigate bimerons on Möbius surfaces and…
Topological magnonic dislocations modes
Carlos Saji, Nicolas Vidal-Silva, Alvaro S. Nunez +1
Spin fluctuations in two-dimensional (2D) ferromagnets in the presence of crystalline lattice dislocations are investigated. We show the existence of topologically protected non-pr…
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…
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…
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…
