Geometric criteria for the absence of effective many-body interactions in nonadditive hard particle mixtures
René Wittmann, Sabine Jansen, Hartmut Löwen
We consider a mixture of small and big classical particles in arbitrary spatial dimensions interacting via hard-body potentials with non-additive excluded-volume interactions. In p…
Revisiting Groeneveld's approach to the virial expansion
Sabine Jansen
A generalized version of Groeneveld's convergence criterion for the virial expansion and generating functionals for weighted -connected graphs is proven. The criterion works for…
Lagrange inversion and combinatorial species with uncountable color palette
Sabine Jansen, Tobias Kuna, Dimitrios Tsagkarogiannis
We prove a multivariate Lagrange-Good formula for functionals of uncountably many variables and investigate its relation with inversion formulas using trees. We clarify the cancell…
Thermodynamics of a hierarchical mixture of cubes
Sabine Jansen
We investigate a toy model for phase transitions in mixtures of incompressible droplets. The model consists of non-overlapping hypercubes in of sidelengths , $j\…
Virial inversion and density functionals
Sabine Jansen, Tobias Kuna, Dimitrios Tsagkarogiannis
We prove a novel inversion theorem for functionals given as power series in infinite-dimensional spaces and apply it to the inversion of the density-activity relation for inhomogen…
A note on the uniqueness result for the inverse Henderson problem
Fabio Frommer, Martin Hanke, Sabine Jansen
The inverse Henderson problem of statistical mechanics concerns classical particles in continuous space which interact according to a pair potential depending on the distance of th…
