Groundwater as a major source of dissolved organic matter to Arctic coastal waters
Nature Communications, 2020 Groundwater is projected to become an increasing source of freshwater and nutrients to the Arctic Ocean as permafrost thaws, yet few studies have quantified groundwater inputs to Arctic coastal waters under contemporary conditions. New measurements along

ESPResSo 4.0 – an extensible software package for simulating soft matter systems [PDF]
The European Physical Journal Special Topics, 2018 ESPResSo is an extensible simulation package for research on soft matter. This versatile molecular dynamics program was originally developed for coarse-grained simulations of charged systems [H.J. Limbach et al., Comput. Phys. Commun.

COLOSSUS: A Python Toolkit for Cosmology, Large-scale Structure, and Dark Matter Halos [PDF]
Astrophysical Journal Supplement Series, 2017 This paper introduces Colossus, a public, open-source python package for calculations related to cosmology, the large-scale structure (LSS) of matter in the universe, and the properties of dark matter halos.

Onsager's variational principle in active soft matter. [PDF]
Soft Matter, 2020 Onsagers variational principle (OVP) was originally proposed by Lars Onsager in 1931 [L. Onsager, Phys. Rev., 1931, 37, 405]. This fundamental principle provides a very powerful tool for formulating thermodynamically consistent models.

Evolution of interfaces and expansion in width [PDF]
, 2000 Interfaces in a model with a single, real nonconserved order parameter and purely dissipative evolution equation are considered. We show that a systematic perturbative approach, called the expansion in width and developed for curved domain walls, can be generalized to the interfaces. Procedure for calculating curvature corrections is described. We also

Temporal chirp, temporal lensing and temporal routing via space-time interfaces [PDF]
arXiv, 2023 A time interface (a rapid change of the constitutive parameters of a material in time), applied within an unbounded medium where a wave travels, can enable frequency conversion, and is considered the temporal analogue of a spatial interface between two materials. Here, we study light-matter interactions in four dimensions, 4D (space, x,y,z, and time, t)

Statics and Dynamics of an Interface in a Temperature Gradient [PDF]
, 1994 The response and nonconserved dynamics of a two-phase interface in the presence of a temperature gradient oriented normally to the interface are considered. Two types of boundary conditions on the order parameter are considered, and the structure of the effective free energy and the Langevin equation for the collective coordinate specifying the ...

The equilibrium intrinsic crystal-liquid interface of colloids [PDF]
Proc Nat Acad Sci 106, 15198-15202 (2009), 2008 We use confocal microscopy to study an equilibrated crystal-liquid interface in a colloidal suspension. Capillary waves roughen the surface, but locally the intrinsic interface is sharply defined. We use local measurements of the structure and dynamics to characterize the intrinsic interface, and different measurements find slightly different widths of

Generalized Total Internal Reflection at Dynamic Interfaces [PDF]
, 2022 Recent research developments in the area of spacetime metamaterial structures and systems have raised new questions as to how the physics of fundamental phenomena is altered in the presence of spacetime modulation. In this context, we present a generalized and comparative description of the phenomenon of total internal reflection (TIR) at different ...

Huge broadening of the crystal-fluid interface for sedimenting colloids [PDF]
Europhysics Letters (2011), 2011 For sedimenting colloidal hard spheres, the propagation and broadening of the crystal-fluid interface is studied by Brownian dynamics computer simulations of an initially homogeneous sample. Two different types of interface broadenings are observed: the first occurs during growth and is correlated with the interface velocity, the second is concomitant ...
