recommendations! Published in 2025 at "Journal of High Energy Physics"

DOI: 10.1007/jhep06(2025)186

Abstract: We derive a general formalism that relates the spectrum of two-particle systems in a finite volume to physical scattering amplitudes, taking into account the presence of any left-hand branch cuts due to single-particle exchanges. The… read more here.

DOI: 10.1007/s00440-024-01357-2

Abstract: We study semi-infinite particle systems on the one-dimensional integer lattice, where each particle performs a continuous-time nearest-neighbour random walk, with jump rates intrinsic to each particle, subject to an exclusion interaction which suppresses jumps that… read more here.

DOI: 10.1007/s40430-020-02465-5

Abstract: This work presents a computational model for the simulation of problems involving thermo-mechanically active particles forming discrete particle systems. Our approach is based on the discrete element method for description of the particles’ dynamics, combined… read more here.

DOI: 10.1016/j.jksus.2017.04.008

Abstract: Abstract Lorentz transformation (LT) was used to link two inertial frames, consisted of moving and lab frames. In addition, the effects of LT on the states of two and one spin-½ particle systems are addressed.… read more here.

DOI: 10.1016/j.powtec.2021.08.017

Abstract: Abstract We present regime maps for subsonic flow in dense gas-particle systems, which demarcate regions of compressible and (effectively) incompressible flow. These maps should aid researchers and industrialists in selecting the appropriate modeling approach, as… read more here.

DOI: 10.1017/fms.2023.27

Abstract: Abstract Conjecture II.3.6 of Spohn in [47] and Lecture 7 of Jensen–Yau in [35] ask for a general derivation of universal fluctuations of hydrodynamic limits in large-scale stochastic interacting particle systems. However, the past few… read more here.

DOI: 10.1088/1742-5468/ab2902

Abstract: In particle systems subject to a nonuniform drive, particle migration is observed from the driven to the non--driven region and vice--versa, depending on details of the hopping dynamics, leading to apparent violations of Fick's law… read more here.

DOI: 10.1088/1751-8121/acda6c

Abstract: We review recent work on systems with multiple interacting-particles having the dynamical feature of stochastic resetting. The interplay of time scales related to inter-particle interactions and resetting leads to a rich behavior, both static and… read more here.
