“…Overall, the constructed B YOCP (r/d, Γ, κ) is expected to be highly accurate since the YOCP is R-simple across the liquid state with very high Pearson correlation coefficients nearly approaching unity and since the insertion of the analytic bridge function of Eqs. (4)(5)(6)(7)(8)(9) in the exact OZ closure has been demonstrated to lead to a highly accurate description of the structural and thermodynamic properties of the OCP [41]. This is not the first time that the OCP bridge function has been employed as an empirical basis for the construction of the YOCP bridge function.…”

“…The YOCP paradigm has been long studied in statistical mechanics being a model system whose interactions can vary from extremely short range hard sphere-like (κ → ∞) to infinitely long range Coulomb-like (κ → 0) depending on the phase diagram region [1]. The experimental realization of the strongly coupled YOCP in complex (dusty) plasmas [2][3][4], charge-stabilized colloidal suspensions [5,6], ultra-cold neutral plasmas [7,8] and their relevance to warm dense matter [9,10] has provided significant impetus to such studies. In fact, a large number of theoretical, computational and experimental works have focused on the structure and thermodynamics [11][12][13], transport coefficients and collective modes [14][15][16] as well as the phase behavior of the YOCP [17,18].…”

Isomorph theory is employed in order to establish a mapping between the bridge function of Coulomb and Yukawa one-component plasmas. Within an exact invariance ansatz for the bridge functions and by capitalizing on the availability of simulation-extracted Coulomb bridge functions, an analytical Yukawa bridge function is derived which is inserted into the integral theory framework. In spite of its simplicity and computational speed, the proposed integral approach exhibits an excellent agreement with computer simulations of dense Yukawa liquids without invoking adjustable parameters.

Charged (nano)particles confined in electrodynamic traps can evolve into strongly correlated Coulomb systems, which are the subject of current investigation. Exciting physical phenomena associated to Coulomb systems have been reported such as autowave generation, phase transitions, system self-locking at the ends of the linear Paul trap, self-organization in layers, or pattern formation and scaling. The dynamics of ordered structures consisting of highly nonideal similarly charged nanoparticles, with coupling parameter of the order Γ = 10 8 is investigated. This approach enables us to study the interaction of nanoparticle structures in presence and in absence of the neutralizing plasma background, as well as to investigate various types of phenomena and physical forces these structures experience. Applications of electrodynamic levitation for mass spectrometry, including containment and study of single aerosols and nanoparticles are reviewed, with an emphasis on state of the art experiments and techniques, as well as future trends. Late experimental data suggest that inelastic scattering can be successfully applied to the detection of biological particles such as pollen, bacteria, aerosols, traces of explosives or synthetic polymers.

“…It can be proven that the optimal effective packing fraction η eff ensuring that B HSPY (r; η eff ) ≈ B(r; n, T ) is acquired by minimizing the VMHNC free energy functional [38]. Hence, the VMHNC closure becomes [38,58] g(r) = exp [−βu(r) + h(r) − c(r) + B HSPY (r; η eff )] (7) and the effective packing fraction η eff is recovered from…”

“…In spite of concerning a simple purely repulsive divergent-atthe-origin pair interaction potential, its variable softness is one reason that the YOCP is still being actively investigated in statistical mechanics studies. The other main reason is the relevance of the YOCP model to strongly coupled laboratory systems such as complex plasmas [2][3][4], charge-stabilized colloidal suspensions [5], ultra-cold neutral plasmas [6,7] and even warm dense matter [8,9].…”

Different advanced bridge function closures are utilized to investigate the structural and thermodynamic properties of dense Yukawa one-component plasma liquids within the framework of integral equation theory. The isomorph-based empirically modified hypernetted-chain, the variational modified hypernetted-chain, the Rogers-Young and the Ballone-Pastore-Galli-Gazzillo approaches are compared at the level of thermodynamic properties, radial distribution functions and bridge functions. The comparison, based on accuracy and computational speed, concludes that the two modified hypernetted-chain approaches are superior and singles out the isomorph-based variant as the most promising alternative to computer simulations of structural properties of dense Yukawa liquids. The possibility of further improvement through artificial cross-over to exact asymptotic limits is studied.
