Vortex Dynamic Phases in Type II Superconducting Strips with Regular and Flattened Triangular Pinning Arrays
(2018-01-01)
The dynamic behavior of vortices in type II superconducting infinite strips is simulated with two types of triangular pinning lattices: the regular one and a flattened triangular array that mimics the vortex lattice in a ...
Phase-separated vortex-lattice in a rotating binary Bose–Einstein condensate
(2019-06-15)
We study circularly-symmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional binary Bose–Einstein condensate (BEC) by introducing a weak quartic trap in one of the ...
Phase-separated symmetry-breaking vortex-lattice in a binary Bose-Einstein condensate
(2020-01-01)
We study spontaneous-symmetry-breaking circularly-asymmetric phase separation of vortex lattices in a rapidly rotating harmonically-trapped quasi-two-dimensional (quasi-2D) binary Bose-Einstein condensate (BEC) with repulsive ...
Latent heat and nonlinear vortex liquid in the vicinity of the first-order phase transition in layered high-Tc superconductors
(American Physical Society, 2014-10-13)
n this work we revisit the vortex matter phase diagram in layered superconductors solving still open questions by means of ac and dc local magnetic measurements in the paradigmatic Bi2Sr2CaCu2O8 compound. We show that ...
Phase slips and vortex dynamics in Josephson oscillations between Bose-Einstein condensates
(Europhysics Letters, 2015-02)
We study the relation between Josephson dynamics and topological excitations in a dilute Bose-Einstein condensate confined in a double-well trap. We show that the phase slips responsible for the self-trapping regime are ...
Role of interstitial pinning in the dynamical phases of vortices in superconducting films
(2013-06-01)
We analyze the vortex dynamics in superconducting thin films with a periodic array of pinning centers. In particular, we study the effect of anisotropy for a Kagomé pinning network when longitudinal and transverse transport ...

Effect of Quenched Disorder in the Entropy-Jump at the First-Order Vortex Phase Transition of Bi2Sr2CaCu2O8+δ
(Springer/Plenum Publishers, 2015-04)
We study the effect of quenched disorder in the thermodynamic magnitudes entailed in the first-order vortex phase transition of the extremely layered Bi2Sr2CaCu2O8+δ compound. We track the temperature-evolution of the ...
Dynamics and heat diffusion of Abrikosov's vortex-antivortex pairs during an annihilation process
(2017-09-04)
The manipulation and control of vortex states in superconducting systems are of great interest in view of possible applications, for which mesoscopic materials are good candidates. In this work, we studied the annihilation ...
Alternate-current dynamic reorganization and nonequilibrium phase transition in driven vortex matter
(American Physical Society, 2020-02)
Externally driven glassy systems may undergo nonequilibrium phase (NEPTs). In particular, ac-driven systems display special features, such as those observed in the vortex matter of NbSe2, where oscillatory drives reorganize ...
