Particlization with local event-by-event conservation laws [PDF]
Physical Review Letters, 2019 We present a sampling method for the transition from relativistic hydrodynamics to particle transport, commonly referred to as particlization, which preserves the local event-by-event conservation of energy, momentum, baryon number, strangeness, and ...

Non Local Conservation Laws in Bounded Domains [PDF]
SIAM Journal on Mathematical Analysis, 2017 The well posedness for a class of non local systems of conservation laws in a bounded domain is proved and various stability estimates are provided. This construction is motivated by the modelling of crowd dynamics, which also leads to define a non local

Generalised conservation laws in non-local field theories [PDF]
Journal of Physics A: Mathematical and Theoretical, 2016 We propose a geometrical treatment of symmetries in non-local field theories, where the non-locality is due to a lack of identification of field arguments in the action.

Translationally invariant conservation laws of local Lindblad equations [PDF]
Journal of Mathematical Physics, 2014 We study the conditions under which one can conserve local translationally invariant operators by local translationally invariant Lindblad equations in one-dimensional rings of spin-1/2 particles.

Numerical preservation of multiple local conservation laws [PDF]
Applied Mathematics and Computation, 2021 There are several well-established approaches to constructing finite difference schemes that preserve global invariants of a given partial differential equation. However, few of these methods preserve more than one conservation law locally. A recently-introduced strategy uses symbolic algebra to construct finite difference schemes that preserve several

Non-local Conservation Law from Stochastic Particle Systems [PDF]
Journal of Dynamics and Differential Equations, 2017 In this paper we consider an interacting particle system in $\mathbb{R}^d$ modelled as a system of $N$ stochastic differential equations driven by L vy processes. The limiting behaviour as the size $N$ grows to infinity is achieved as a law of large numbers for the empirical density process associated with the interacting particle system.

Computers & Fluids, 2022 We are interested in building schemes for the compressible Euler equations that are also locally conserving the angular momentum. We present a general framework, describe a few examples of schemes and show results. These schemes can be of arbitrary order.

Computational Bounds to Light–Matter Interactions via Local Conservation Laws [PDF]
Physical Review Letters, 2020 We develop a computational framework for identifying bounds to light-matter interactions, originating from polarization-current-based formulations of local conservation laws embedded in Maxwell's equations. We propose an iterative method for imposing only the maximally violated constraints, enabling rapid convergence to global bounds. Our framework can

Adaptive total variation stable local timestepping for conservation laws
Journal of Computational Physics, 2022 This paper proposes a first-order total variation diminishing (TVD) treatment for coarsening and refining of local timestep size in response to dynamic local variations in wave speeds for nonlinear conservation laws. The algorithm is accompanied with a proof of formal correctness showing that given a sufficiently small minimum timestep the algorithm ...
