Graphics Processing Unit Accelerated Lattice Boltzmann Method Simulations of Dilute Gravity Currents [PDF]

open access: yesPhysics of Fluids, 2022
Lattice Boltzmann method models offer a novel framework for the simulation of high Reynolds number dilute gravity currents. The numerical algorithm is well suited to acceleration via implementation on massively parallel computer architectures.

Planar diagrams, two-dimensional lattice gravity and surface models

open access: yesNuclear Physics B, 1985
Abstract Some discrete lattice models for quantum two-dimensional euclidean gravity are shown to be equivalent to zero-dimensional planar field theories. Explicit expressions are given for partition functions. A universal continuum limit exists for open surfaces, but not for closed ones, and is argued to describe a space with negative average ...

Lessons from Toy-Models for the Dynamics of Loop Quantum Gravity [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2012
We review some approaches to the Hamiltonian dynamics of (loop) quantum gravity, the main issues being the regularization of the Hamiltonian and the continuum limit.

Decoding Viral Transmission Dynamics in Structured Populations Using a Microfluidic Herd-Immunity-on-a-Chip Platform. [PDF]

open access: yesAdv Sci (Weinh)
A microfluidic Herd‐Immunity‐on‐a‐Chip experimentally recreates structured contact networks to quantify viral transmission dynamics. By controlling susceptible, infected, and non‐susceptible populations, the platform reveals how contact topology governs the reproduction number, outbreak propagation, herd‐immunity–like behavior, and intervention ...

Analytical solution of axi-symmetrical lattice Boltzmann model for cylindrical Couette flows [PDF]

open access: yes, 2012
Analytical solution for the axi-symmetrical lattice Boltzmann model is obtained for the low-Mach number cylindrical Couette flows. In the hydrodynamic limit, the present solution is in excellent agreement with the result of the Navier-Stokes equation ...

Perfect discretizations as a gateway to one-loop partition functions for 4D gravity

open access: yesJournal of High Energy Physics, 2022
Lattice actions and amplitudes that perfectly mirror continuum physics are known as perfect discretizations. Such perfect discretizations naturally preserve the symmetries of the continuum.

A MODEL OF THREE-DIMENSIONAL LATTICE GRAVITY [PDF]

open access: yesModern Physics Letters A, 1992
A model is proposed which generates all oriented 3D simplicial complexes weighted with an invariant associated with a topological lattice gauge theory. When the gauge group is SU q (2), q n =1, it is the Turaev-Viro invariant and the model may be ...

The phase structure of causal dynamical triangulations with toroidal spatial topology

open access: yesJournal of High Energy Physics, 2018
We investigate the impact of topology on the phase structure of fourdimensional Causal Dynamical Triangulations (CDT). Using numerical Monte Carlo simulations we study CDT with toroidal spatial topology.
