Structural crossovers of quasi-one-dimensional patchy hard superellipses
Sakineh Mizani, Martin Oettel, Péter Gurin +1
We study a quasi-one-dimensional associating fluid composed of hard superellipses carrying two patches interacting through a directional Kern--Frenkel potential. Using the Transfer…
Thermodynamic and structural behavior of one-dimensional divalent patchy hard rods: Wertheim's first-order thermodynamic perturbation theory vs exact results
