Fractional particle and sigma model

Journal of High Energy Physics
We introduce a classical fractional particle model in ℝ n , extending the Newtonian particle concept with the incorporation of the fractional Laplacian.

Particle-based Ising model [PDF]

Physical Review E, 2021
We characterize equilibrium properties and relaxation dynamics of a two-dimensional lattice containing, at each site, two particles connected by a double-well potential (dumbbell). Dumbbells are oriented in the orthogonal direction with respect to the lattice plane and interact with each other through a Lennard-Jones potential truncated at the nearest ...

Spatially hybrid computations for streamer discharges: II. Fully 3D simulations [PDF]

, 2011
We recently have presented first physical predictions of a spatially hybrid model that follows the evolution of a negative streamer discharge in full three spatial dimensions; our spatially hybrid model couples a particle model in the high field region ...

A Flexible Particle Model for Rock Fracture: Validation and Assessment of the Influence of Deformability on the Macroscopic Response

Geotechnics, 2022
Circular/spherical rigid particle models that were initially applied to rock fracture studies were not able to match the ratio of the compressive strength to tensile strength that occurs in rock.

Prediction of Rubble-Stone Masonry Walls Response under Axial Compression Using 2D Particle Modelling

Buildings, 2022
To predict the structural behaviour of ancient stone masonry walls is still a challenging task due to their strong heterogeneity. A rubble-stone masonry modeling methodology using a 2D particle model (2D-PM), based on the discrete element method is ...

Implementation of a Lagrangian Stochastic Particle Trajectory Model (LaStTraM) to Simulate Concentration and Flux Footprints Using the Microclimate Model ENVI-Met

Atmosphere, 2021
The number of studies evaluating flux or concentration footprints has grown considerably in recent years. These footprints are vital to understand surface–atmosphere flux measurements, for example by eddy covariance.

Numerical Evaluation of Transverse Steel Connector Strengthening Effect on the Behavior of Rubble Stone Masonry Walls under Compression Using a Particle Model

Buildings, 2023
The structural rehabilitation of historic/traditional rubble masonry wall constructions requires consolidation and retrofitting solutions to be employed in order to withstand dynamic loads, high vertical loads, and differential settlements.

CALOGERO MODELS FOR DISTINGUISHABLE PARTICLES [PDF]

Modern Physics Letters B, 1995
Motivated by topological bidimensional quantum models for distinguishable particles, and by Haldane's definition of mutual statistics for different species of particles, we propose a new class of one-dimensional [Formula: see text] Calogero model with coupling constants gij depending on the labels of the particles.

Simple Particle Model for Low-Density Granular Flow Interacting with Ambient Fluid

Geosciences, 2020
To understand the time evolutions of frontal speed and shape in a low-density granular flow, we propose a simple particle model. This model solves the equation of motion for each particle and simulates the time evolution of low-density granular flow ...

A Particle System Model for Dengue Transmission

Communication in Biomathematical Sciences, 2017
Dengue disease has been known for decades as a vector-borne disease which is rapidly spreading in many tropical and subtropical countries. The disease is transmitted mostly by female Aedes aegypty mosquitoes.
