Dreaming neural networks: rigorous results
Elena Agliari, Francesco Alemanno, Adriano Barra +1
Recently a daily routine for associative neural networks has been proposed: the network Hebbian-learns during the awake state (thus behaving as a standard Hopfield model), then, du…
Study of longitudinal fluctuations of the Sherrington-Kirkpatrick model
Giorgio Parisi, Leopoldo Sarra, Lorenzo Talamanca
We study finite-size corrections to the free energy of the Sherrington-Kirkpatrick spin glass in the low temperature phase. We investigate the role of longitudinal fluctuations in…
Magnetic control of polariton spin transport
Davide Caputo, Evgeny Sedov, Dario Ballarini +3
We show the full control of the polarization dynamics of a propagating exciton-polariton condensate in a planar microcavity by using a magnetic field applied in the Voigt geometry.…
Josephson vortices in a long Josephson junction formed by phase twist in a polariton superfluid
Davide Caputo, Nataliya Bobrovska, Dario Ballarini +7
Quantum fluids of light are an emerging platform for energy efficient signal processing, ultra-sensitive interferometry and quantum simulators at elevated temperatures. Here we dem…
A First-Order Dynamical Transition in the displacement distribution of a Driven Run-and-Tumble Particle
Giacomo Gradenigo, Satya N. Majumdar
We study the probability distribution of the total displacement of an -step run and tumble particle on a line, in presence of a constant nonzero drive . Wh…
Two-Dimensional hybrid perovskites sustaining strong polariton interactions at room temperature
A. Fieramosca, L. Polimeno, V. Ardizzone +9
Polaritonic devices exploit the coherent coupling between excitonic and photonic degrees of freedom to perform highly nonlinear operations with low input powers. Most of the curren…
Tunable out-of-plane excitons in 2D single crystal perovskites
A. Fieramosca, L. De Marco, M. Passoni +11
Hybrid organic-inorganic perovskites have emerged as very promising materials for photonic applications, thanks to the great synthetic versatility that allows to tune their optical…
Self-trapping of exciton-polariton condensates
Dario Ballarini, Igor Chestnov, Davide Caputo +7
The self-trapping of exciton-polariton condensates is demonstrated and explained by the formation of a new polaron-like state. Above the polariton lasing threshold, local variation…
An innovative, fast and facile soft-template approach for the fabrication of porous PDMS for oil-water separation
A. Turco, E. Primiceri, M. Frigione +2
Oil wastewater and spilled oil caused serious environmental pollution and damage to public health in the last years. Therefore, considerable efforts are made to develop sorbent mat…
Exploration-exploitation tradeoffs dictate the optimal distributions of phenotypes for populations subject to fitness fluctuations
Andrea De Martino, Thomas Gueudré, Mattia Miotto
We study a minimal model for the growth of a phenotypically heterogeneous population of cells subject to a fluctuating environment in which they can replicate (by exploiting availa…
CdSe/CdS dot-in-rods nanocrystals fast blinking dynamics
Mathieu Manceau, Stefano Vezzoli, Quentin Glorieux +5
The blinking dynamics of colloidal core-shell CdSe/CdS dot-in-rods is studied in detail at the single particle level. Analyzing the autocorrelation function of the fluorescence int…
Nanostructured Hyperbolic Meta-Antennas Enable Arbitrary Control of Scattering vs Absorption
Nicolò Maccaferri, Yingqi Zhao, Marzia Iarossi +4
We show that meta-antennas made of a composite material displaying type II hyperbolic dispersion enable precise and controlled spectral separation of absorption and scattering proc…
Approximate Survey Propagation for Statistical Inference
Fabrizio Antenucci, Florent Krzakala, Pierfrancesco Urbani +1
Approximate message passing algorithm enjoyed considerable attention in the last decade. In this paper we introduce a variant of the AMP algorithm that takes into account glassy na…
Currents and flux-inversion in photokinetic active particles
Claudio Maggi, Luca Angelani, Giacomo Frangipane +1
Many active particles, both of biological and synthetic origin, can have a light controllable propulsion speed, a property that in biology is commonly referred to as photokinesis.…
Effect of dilution in asymmetric recurrent neural networks
Viola Folli, Giorgio Gosti, Marco Leonetti +1
We study with numerical simulation the possible limit behaviors of synchronous discrete-time deterministic recurrent neural networks composed of N binary neurons as a function of a…
UV Light Detection from CdS Nanocrystal Sensitized Graphene Photodetectors at kHz Frequencies
Davide Spirito, Stefan Kudera, Vaidotas Miseikis +3
We have fabricated UV-sensitive photodetectors based on colloidal CdS nanocrystals and graphene. The nanocrystals act as a sensitizer layer that improves light harvesting leading t…
Glassy nature of the hard phase in inference problems
Fabrizio Antenucci, Silvio Franz, Pierfrancesco Urbani +1
An algorithmically hard phase was described in a range of inference problems: even if the signal can be reconstructed with a small error from an information theoretic point of view…
Computation of the Zero Temperature RSB parameter in Bethe Lattice Spin Glasses
Francesco De Santis, Giorgio Parisi
Bethe Lattice Spin Glasses (BLSG) are models with finite connectivity which undergo a Replica Symmetry Breaking (RSB) phase transition in field, even at zero temperature. The order…
