Este jueves 30 de mayo tenemos un nuevo Seminario de Sistemas Complejos en IFIS. Desde las 14:30 hrs en la sala 208, En esta ocasión, la profesora Mónica García, presentará “Fluxon-like Bubble Dynamics in Josephson Junctions as a Window to Complex Behavior”.
Te dejamos el abstract de la presentación:
Bubble-like fluxons in Josephson junctions provide a fertile setting for the study of nonlinear excitations, stability mechanisms, and resonant dynamics in driven condensed-matter systems. In this talk, I present recent analytical and numerical results demonstrating how coaxial dipole currents can stabilize bubble fluxons in disk-shaped junctions. Furthermore, I examine the system’s response to rapid microwave forcing, which reveals two distinct dynamical regimes and a transition from externally driven to intrinsic oscillations. These results highlight the interplay between geometrical constraints, internal modes, and high-frequency fields in shaping fluxon stability. In line with the spirit of the 2025 Nobel Prize in Physics, this work underscores how coherent nonlinear excitations in superconducting circuits continue to illuminate fundamental physics while paving the way toward future quantum technologies.
