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,…

Raman spectroscopy of femtosecond multi-pulse irradiation of vitreous silica: experiment and simulation

N. S. Shcheblanov, M. E. Povarnitsyn, K. N. Mishchik +1

We report an experimental and numerical study of femtosecond multi-pulse laser-induced densification in vitreous silica (v-SiO2) and its signature in Raman spectra. We compare the…

Experimental Evidence of Fluctuation-Dissipation Theorem Violation in a Superspin Glass

Katsuyoshi Komatsu, D. L'Hote, Sawako Nakamae +5

We present the experimental observation of the fluctuation-dissipation theorem (FDT) violation in an assembly of interacting magnetic nanoparticles in the low temperature superspin…

"de Gennes" narrowing in supercooled molecular liquids : Evidence for center-of-mass dominated slow dynamics

C. Alba-Simionesco, A. Toelle, D. Morineau +2

The density correlation function F(q,t) of the two similar substituted aromatic liquids, Toluene and m-Toluidine, is studied by coherent neutron spin-echo and time-of-flight scatte…
