Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at $\sqrt{s} =$ 13 ...
...
Evidence is presented for the electroweak (EW) production of two jets (jj) in association with two Z bosons and constraints on anomalous quartic gauge couplings are set. The analysis is based on a data sample of proton-proton collisions at $\sqrt{s}= $ 13 TeV collected with the CMS detector in 2016-2018, and corresponding to an integrated luminosit...
2020 beyond COVID: the other science events that shaped the year

Evidence of shock-compressed stishovite above 300 GPa
...Published in Scientific Reports
SiO2 is one of the most fundamental constituents in planetary bodies, being an essential building block of major mineral phases in the crust and mantle of terrestrial planets (1–10 ME). Silica at depths greater than 300 km may be present in the form of the rutile-type, high pressure polymorph stishovite (P42/mnm) and its thermodynamic stability is ...
Additive rheology of complex granular flows
Published in Nature Communications
Granular materials are abundant in nature, but we haven’t fully understood their rheological properties as complex interactions between particles are involved. Here, Vo et al. show that granular flows can be described by a generalized dimensionless number based on stress additivity.

Multiscale electronic and thermomechanical dynamics in ultrafast nanoscale laser structuring of bulk fused silica
Published in Scientific Reports
We describe the evolution of ultrafast-laser-excited bulk fused silica over the entire relaxation range in one-dimensional geometries fixed by non-diffractive beams. Irradiation drives local embedded modifications of the refractive index in the form of index increase in densified glass or in the form of nanoscale voids. A dual spectroscopic and ima...
Sensitivity to losses and defects of the symmetry-induced transmission enhancement through diffusive slabs
Published in Scientific Reports
We inspect the robustness to absorption and to symmetry defects of the symmetry-induced broadband enhancement through opaque barriers in disordered slabs. The sensitivity of this phenomenon to symmetry defects is found to be strongly related to the distance from to barrier to the nearest defect, and, following, we propose a probabilistic model to e...
Influence of flicker noise and nonlinearity on the frequency spectrum of spin torque nano-oscillators
...Published in Scientific Reports
The correlation of phase fluctuations in any type of oscillator fundamentally defines its spectral shape. However, in nonlinear oscillators, such as spin torque nano-oscillators, the frequency spectrum can become particularly complex. This is specifically true when not only considering thermal but also colored 1/f flicker noise processes, which are...
