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…
Hyperuniform vortex patterns at the surface of type-II superconductors
Gonzalo Rumi, Jazmin Aragon Sanchez, Federico Elias +7
A many-particle system must posses long-range interactions in order to be hyperuniform at thermal equilibrium. Hydrodynamic arguments and numerical simulations show, nevertheless,…
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…
