Recent experiments with a rotating probe immersed in weakly fluidized granular materials show a complex behavior on a wide range of time scales. Viscous-like relaxation at high frequency is accompanied by an almost harmonic dynamical trapping at intermediate times, with possibly anomalous long time behavior in the form of super-diffusion. Inspired by the itinerant oscillator model for diffusion in molecular liquids, and other models with coupled thermostats acting at different time scales, here… 
Dynamical Collective Memory in Fluidized Granular Materials.
TLDR
A persistent collective rotational mode which emerges at a high density and a low granular temperature is discovered: a macroscopic fraction of the medium slowly rotates, randomly switching direction after very long times, which is the origin of the probe's superdiffusion.
Unified rheology of vibro-fluidized dry granular media: From slow dense flows to fast gas-like regimes
TLDR
A broad rheological scenario where average stress sums up a frictional contribution, generalizing conventional μ(I)-rheology, and a kinetic collisional term dominating at fast fluidization is proposed.
Cage model of polar fluids: Finite cage inertia generalization.
The itinerant oscillator model describing rotation of a dipole about a fixed axis inside a cage formed by its surrounding polar molecules is revisited in the context of modeling the dielectric
Langevin equations from experimental data: The case of rotational diffusion in granular media
TLDR
This work applies a Langevin-type stochastic equation derivation procedure to the data obtained in a rotational granular diffusion experiment, showing the power of this method and the theoretical issues behind its limits.
Anomalous diffusion of a dipole interacting with its surroundings.
A fractional Fokker-Planck equation based on the continuous time random walk Ansatz is written via the Langevin equations for the dynamics of a dipole interacting with its surroundings, as
Active Mechanics Reveal Molecular-Scale Force Kinetics in Living Oocytes
TLDR
Study of the active diffusion of vesicles in mouse oocytes reveals that measuring in vivo active fluctuations allows extraction of the molecular-scale activity in agreement with single-molecule studies and demonstrates a mesoscopic framework to access force kinetics.
The Role of Data in Model Building and Prediction: A Survey Through Examples
TLDR
A review of key examples from Physics, taken from dynamical systems theory, biophysics, and statistical mechanics, representing three paradigmatic procedures to build models and predictions from available data, show how predictions can be obtained in a virtually model-free framework using the methods of analogues.
Correlation functions of non-Markovian systems out of equilibrium: analytical expressions beyond single-exponential memory
This paper is concerned with correlation functions of stochastic systems with memory, a prominent example being a molecule or colloid moving through a complex (e.g. viscoelastic) fluid environment.
Slow time scales in a dense vibrofluidized granular material.
TLDR
A phenomenological model for the tracer (fast and slow) dynamics, which consists in a stochastic system of equations for three coupled variables, and is therefore more refined and successful than previous models.

Cages and anomalous diffusion in vibrated dense granular media.
TLDR
A vertically shaken granular medium hosts a blade rotating around a fixed vertical axis, which acts as a mesorheological probe, which shows strong caging effects and a power-law decay, likely due to persistent collective fluctuations of the host medium.
Nonequilibrium Brownian Motion beyond the Effective Temperature
TLDR
The mixed timescale regime is studied by studying fluctuations and linear response in the Brownian motion of a rotating intruder immersed in a vibro-fluidized granular medium and the GFDT is able to impute the emergence of a strong coupling between the intruder and the surrounding fluid.
Critical scaling and heterogeneous superdiffusion across the jamming/rigidity transition of a granular glass
The dynamical properties of a dense horizontally vibrated bidisperse granular monolayer are experimentally investigated. The quench protocol produces states with a frozen structure of the assembly,
Superdiffusive, heterogeneous, and collective particle motion near the fluid-solid transition in athermal disordered materials
We use computer simulations to study the microscopic dynamics of an athermal assembly of soft particles near the fluid-to-solid jamming transition. Borrowing tools developed to study dynamic
Coarsening in granular systems
We review a few representative examples of granular experiments or models where phase separation, accompanied by domain coarsening, is a relevant phenomenon. We first elucidate the intrinsic
Long-time tails and cage effect in driven granular fluids.
TLDR
At moderate densities the velocity autocorrelation function is shown to decay algebraically in time, like t (-3/2), if momentum is conserved locally, and like t(-1), if Momentum is not conserved by the driving.
Subdiffusion and cage effect in a sheared granular material.
TLDR
This work investigates experimentally the diffusion properties of a bidimensional bidisperse dry granular material under quasistatic cyclic shear and studies the cage dynamics responsible for the subdiffusion in the slow relaxation regime.
Caging dynamics in a granular fluid.
TLDR
An experimental investigation of the caging motion in a uniformly heated granular fluid for a wide range of filling fractions, varphi, and speculate that this is due to a process of structural arrest provided, in this case, by the presence of crystallization.
Observing brownian motion in vibration-fluidized granular matter
TLDR
An experimental investigation of an archetypal non-equilibrium system, involving a sensitive torsion oscillator immersed in a granular system of millimetre-size grains that are fluidized by strong external vibrations, finds that the vibro-fluidized granular matter behaves as a ‘thermal’ bath satisfying a fluctuation-dissipation relation.
Nonlinear driven diffusive systems with dissipation: fluctuating hydrodynamics.
TLDR
This work considers a general class of nonlinear diffusive models with bulk dissipation and boundary driving and derives its hydrodynamic description in the large size limit, the simplest nonlinear dissipative variant of the so-called KMP model for heat transport.
