Strongly correlated model of acousticlike plasmons persisting across the phase diagram of cuprate superconductors

Luciano Zinni, Hiroyuki Yamase, Matthias Hepting +2

Layered two-dimensional electron systems exhibit both optical and acousticlike plasmons around the Brillouin-zone center. In the layered cuprate LaSrCuO, resonant i…

Statistics of correlations in nonlinear recurrent neural networks

German Mato, Facundo Rigatuso, Gonzalo Torroba

The statistics of correlations are central quantities characterizing the collective dynamics of recurrent neural networks. We derive exact expressions for the statistics of correla…

Systematic study of the morphology and length of slow stable hybrid star branches

Mauro Mariani, Milva G. Orsaria, Germán Lugones +1

We introduce and systematically study the length of the slow stable hybrid star branch as a quantitative measure of the extended stability region that arises in hybrid neutron star…

Reducibility of higher-order to pairwise interactions: Social impact models on hypergraphs

Jaume Llabrés, Raúl Toral, Maxi San Miguel +1

We show that a general class of social impact models with higher-order interactions on hypergraphs can be exactly reduced to an equivalent model with pairwise interactions on a wei…

Hubble tension and small-scale inhomogeneities on light propagation

Lucila Kraiselburd, Cassio Pigozzo, Susana J. Landau +1

Context. A major observational challenge within the standard cosmological framework is the Hubble tension, a statistically significant () disagreement between the Hubble…

Vortex dynamics in rotating dipolar supersolids across Josephson and self-trapping regimes

Aitor Alaña, Michele Modugno, Pablo Capuzzi

We investigate vortex nucleation and transport in a rotating dipolar supersolid arranged in a triangular droplet lattice, exploiting its description as an array of weakly linked co…
