Two layers of dry granular particles of different density are initially superimposed in an unstable configuration, the layer of dense particles above. This layering is set in motion, numerically by tilting the gravity in discrete element me...
Kilotesla magnetic field generation via ultraintense laser interaction with hollow microcapsule [0.03%]

We investigate the generation of kilotesla-level magnetic fields in laser-irradiated hollow conical targets through particle-in-cell simulations. This configuration proves effective in producing magnetic fields tens of kiloteslas in strengt...
Two-loop turbulent helical magnetohydrodynamics: Large-scale dynamo and energy spectrum [0.03%]
双环螺旋磁流体动力学:大尺度发电机和能量光谱

Michal Hnatič et al.
We present a two-loop field-theoretic analysis of incompressible helical magnetohydrodynamics (MHD) in fully developed stationary turbulence. A key feature of helical MHD is the appearance of an infrared-unstable "masslike" term in the loop...
Thermodynamic interpretation to stochastic Fisher information and single-trajectory speed limits [0.03%]
基于随机Fisher信息的热力学诠释及单轨迹速度极限

The Fisher information (FI) metric is a Riemannian metric that allows a geometric treatment of stochastic thermodynamics, introducing the possibility of computing thermodynamic lengths and deviations from equilibrium. At the trajectory leve...

Time nonlocality, or memory, is a nonequilibrium property shared by all physical systems. Here, we show that memory is sufficient to induce a phase of spatial long-range order (LRO) even if the system's primary dynamical variables are coupl...

We consider a one-dimensional array of particles interacting via an infinite well potential. We explore the properties of energy spreading from an initial state where only a group of particles has nonzero velocities, while others are at res...

We study the self-assembly of magnetic colloids using the Stockmayer (SM) model characterized by short-range Lennard-Jones interactions and long-range dipole-dipole interactions. Using molecular dynamics simulations, we design cooling proto...
Lattice gas automata with floating-point numbers: A connection between molecular dynamics and lattice Boltzmann method for quantum computers [0.03%]

Building upon the Integer Lattice Gas Automata framework of Blommel and Wagner [Phys. Rev. E 97, 023310 (2018)2470-004510.1103/PhysRevE.97.023310], we introduce a simplified, fluctuation-free variant. This approach relies on floating-point ...
Quantification of ion scattering by solar-wind current sheets: Pitch-angle diffusion rates [0.03%]

The transport of energetic particles in the heliosphere is profoundly influenced by interactions with coherent structures in the turbulent magnetic field of the solar wind, particularly current sheets. While prior studies have largely relie...

Network geometry, characterized by nodes with associated latent variables, is a fundamental feature of real-world networks. Still, when only the network edges are given, it may be difficult to assess whether the network contains an underlyi...
