Density Modulations of Zero Sound
Annalen der Physik, Volume 538, Issue 2, February 2026.Zero sound is a collective mode of the strongly interacting quantum gas that propagates when atomic collisions are negligible, similarly to a plasmon. This work aims at investigating the conditions under which a density modulation associated to this collective mode travels coherently through a strongly interacting Fermi gas.

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis
International Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...

Efficient upwind algorithms for solution of the Euler and Navier-stokes equations [PDF]
, 1995 An efficient three-dimensionasl tructured solver for the Euler and Navier-Stokese quations is developed based on a finite volume upwind algorithm using Roe fluxes. Multigrid and optimal smoothing multi-stage time stepping accelerate convergence.

Droplet, Volume 5, Issue 1, January 2026.Engineered topologies surfaces with special wettability are promising for their ability to precisely customize wetting behaviors and incorporate versatile functionalities, setting them apart from randomly structured surfaces. However, robustness and durability have been hurdles to their broad application.

Engineering Reports, Volume 8, Issue 1, January 2026.Experimental measurements reveal distinct performance boundaries: TMM achieves rapid convergence (< 2 dB error below 2000 Hz) but neglects 3D wave effects; FEA maintains < 10% deviation up to 3500 Hz with 90% reduced computational cost versus CFD; while transient CFD captures broadband attenuation trends despite 10× higher resource demands.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract A number of mechanisms have been suggested to operate within the terrestrial bow shock to redistribute energy contained in the incoming solar wind flow. The majority of mechanisms involve the generation of turbulence while some are based on particle motion alone.
