Filaments have been studied in detail through observations and simulations. A range of numerical works separately investigated how chemistry diffusion effects, as well magnetic fields their structure impact the gas dynamics filament. However, non-ideal effects hardly explored thus far. We investigate magnetohydrodynamic (MHD) combined with a simplified chemical model affect evolution accretion ...

Non-Hermitian systems exhibit nontrivial band topology and a strong sensitivity of the energy spectrum on boundary conditions. Remarkably, macroscopic number bulk states get squeezed toward lattice edges under open conditions, an effect dubbed non-Hermitian skin (NHSE). A well-established dynamical signature NHSE in real space is directional flow (or persistent current) for arbitrary initial ex...
