Signatures of nematic quantum critical fluctuations in the Raman spectra of lightly doped cuprates
S. Caprara, M. Colonna, C. Di Castro +4
We consider the lightly doped cuprates YCaBaCuO and LaSrCuO (with ,0.04), where the presence of a fluctuating nematic state has o…
Urban skylines from Schelling model
Floriana Gargiulo, Yerali Gandica, Timoteo Carletti
We propose a metapopulation version of the Schelling model where two kinds of agents relocate themselves, with unconstrained destination, if their local fitness is lower than a tol…
Cages and anomalous diffusion in vibrated dense granular media
Camille Scalliet, Andrea Gnoli, Andrea Puglisi +1
A vertically shaken granular medium hosts a blade rotating around a fixed vertical axis, which acts as a mesorheological probe. At high densities, independently from the shaking in…
Twitter-based analysis of the dynamics of collective attention to political parties
Young-Ho Eom, Michelangelo Puliga, Jasmina Smailović +2
Large-scale data from social media have a significant potential to describe complex phenomena in real world and to anticipate collective behaviors such as information spreading and…
Violent relaxation of ellipsoidal clouds
David Benhaiem, Francesco Sylos Labini
An isolated, initially cold and ellipsoidal cloud of self-gravitating particles represents a relatively simple system to study the effects of the deviations from spherical symmetry…
Coarsening dynamics at unstable crystal surfaces
Paolo Politi
In this paper we focus on crystal surfaces led out of equilibrium by a growth or erosion process. As a consequence of that the surface may undergo morphological instabilities and d…
