Second ac screening step as a probe for the first-order melting transition in layered vortex matter at intermediate temperatures
Gonzalo Rumi, Pablo Pedrazzini, Hernán Pastoriza +2
We present a new probe for the first-order transition for layered vortex matter: A second step in the screening of an ac field that is independent of the frequency and amplitude of…
Angularly Selective Enhanced Vortex Screening in Extremely Layered Superconductors with Tilted Columnar Defects
Gonzalo Rumi, Vincent Mosser, Marcin Konczykowski +1
We report on two mechanisms of angularly selective enhanced screening in the solid vortex phase of extremely layered superconductors with tilted columnar defects (CDs). We study Bi…
Anisotropic suppression of hyperuniformity of elastic systems in media with planar disorder
Joaquín Puig, Federico Elías, Jazmín Aragón Sanchez +6
Disordered hyperuniform materials with vanishing long-wavelength density fluctuations are attracting attention due to their unique physical properties. In these systems, the large-…
Non-Gaussian tail in the force distribution: A hallmark of correlated disorder in the host media of elastic objects
Jazmín Aragón Sánchez, Gonzalo Rumi, Raúl Cortés Maldonado +9
Inferring the nature of disorder in the media where elastic objects are nucleated is of crucial importance for many applications but remains a challenging basic-science problem. He…
Unveiling the vortex glass phase in the surface and volume of a type-II superconductor
Jazmín Aragón Sánchez, Raúl Cortés Maldonado, Néstor René Cejas Bolecek +11
Order-disorder transitions between glassy phases are quite common in nature and yet a comprehensive survey of the microscopic structural changes remains elusive since the scale of…
Entropy jump at the first-order vortex phase transition in Bi2Sr2CaCu2O8+δ with columnar defects
G. Rumi, L. J. Albornoz, P. Pedrazzini +5
We study the entropy jump associated with the first-order vortex melting transition (FOT) in Bi2Sr2CaCu2O8+δ crystals by means of Hall probe magnetometry. The samples present a dil…
