On non-phononic modes and glassy dynamics
Felix C. Mocanu, Dmytro Khomenko, Matteo Paoluzzi +4
The relationship between vibrational modes and glassy dynamics has been an important and controversial topic of study for many decades. We introduce a family of glass-forming model…
Structural Identifiability and Comparative Calibration of Water Retention Curves for Imbibition in Porous Media
Gabriella Bretti, Maurizio Ceseri, Elia Onofri +1
This paper investigates the structural identifiability and a comparative calibration of four water retention curves (WRCs) within the framework of the Richards equation coupled wit…
Fluidization induced by Magnetic Interactions in Confined Active Matter
Marco Musacchio, Markus Felber, Matteo Paoluzzi +3
We investigate magnetic active matter in confined geometries using both experiments with magnetic toy robots Hexbugs and simulations of elongated magnetic active Brownian particles…
Macroscopic active matter under confinement: dynamical heterogeneity, bursts, and glassy behavior in a few-body system of self-propelling camphor surfers
Marco Leoni, Matteo Paoluzzi, Christian Alistair Dumaup +5
We study a few-body system composed of self-propelling camphor surfers confined within a circular boundary. These millimeter-sized particles move in a regime where inertia and long…
Further testing the validity of generalized heterogeneous-elasticity theory for low-frequency excitations in structural glasses
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
We summarize the salient features of our theory of non-phononic vibrational excitations in glasses [W. Schirmacher et al., Nature Comm. 15, 3107 (2024)]. Next, we provide further e…
Local entropy production rate of run-and-tumble particles
Matteo Paoluzzi, Andrea Puglisi, Luca Angelani
We study the local entropy production rate and the local entropy flow in active systems composed of non-interacting run-and-tumble particles in a thermal bath. After providing gene…
Rosette formations as symmetry-breaking events: theory and experiment
Mattia Miotto, Giorgio Gosti, Maria Rosito +6
Multicellular rosettes are observed in different situations such as morphogenesis, wound healing, and cancer progression. While some molecular insights have been gained to explain…
Wave front propagation in the Active Coagulation Model
Matteo Paoluzzi
Spreading processes on top of active dynamics provide a novel theoretical framework for capturing emerging collective behavior in living systems. I consider run-and-tumble dynamics…
Non-equilibrium phase transitions in hybrid Voronoi models of cell colonies
Mattia Miotto, Giancarlo Ruocco, Matteo Paoluzzi
Eukaryotic cells are characterized by a stiff nucleus whose effect in modeling the collective behavior of cell aggregates is usually underestimated. However, increasing experimenta…
Entropy production of run-and-tumble particles
Matteo Paoluzzi, Andrea Puglisi, Luca Angelani
We analyze the entropy production in run-and-tumble models. After presenting the general formalism in the framework of the Fokker-Planck equations in one space dimension, we derive…
Motility driven glassy dynamics in confluent epithelial monolayers
Souvik Sadhukhan, Manoj Kumar Nandi, Satyam Pandey +4
As wounds heal, embryos develop, cancer spreads, or asthma progresses, the cellular monolayer undergoes glass transition between solid-like jammed and fluid-like flowing states. Du…
The nature of non-phononic excitations in disordered systems
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
Using heterogeneous-elasticity theory (HET) and a generalisation of HET theory (GHET), obtained by applying a newly developed procedure for obtaining the continuum limit of the gla…
