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…
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…
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…
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…
