In the mid-1970s, the European physics community initiated a series of international conferences called the Middle European Cooperation in Statistical Physics (MECO). During the last two decades of the Cold War, the conference series allowed statistical physicists in the East and West to maintain open scientific dialogue and beneficial cooperation across the Iron Curtain. Since their establishment, the MECO conferences have become one of the most prestigious forums in statistical physics and related disciplines.
Among these six posters, three posters will be chosen by the jury of poster session leaders, and the other three by the conference participants. Prizes will be awarded to three posters that collect the highest number of markers and three posters chosen by the jury. The effect of barrier transparency on the stationary properties of SIS-type superconducting junctions.
On the new concept for an extended van der Waals theory of vapor-liquid equilibria. Longitudinal and transverse dielectric, piezoelectric, elastic, dynamic and thermal properties of the Rochelle salt NaKC4H4O6 ·4H2O.

Abstracts
Finally, we discuss the physical implications of the results vis-à-vis the universal relaxation mentioned above. Despite a significant progress in continuum description of atomic configurations using PFC method, the physical origin of the gradient terms in this model has not been established. It has been shown that the choice of the gradient terms in PFC approximation is equivalent to a smooth atom approximation.
As the critical point is approached, we observe long-range interactions, which are either attractive or repulsive depending on the specific boundary conditions of the walls. The critical Casimir effect results from limiting the pronounced thermal fluctuations that occur upon approaching a second-order phase transition, such as the demixing of a binary liquid mixture. The spatial direction of the force acting on the bounding surfaces can be controlled by appropriately modeling these surfaces.
External perturbations affect the strength of the critical Casimir force, whose time dependence shows interesting features. We interpret the λ surface as a boundary between homogeneous and inhomogeneous (containing clusters or other aggregates) structure of the disordered phase.
Oral Contributions
The Widom line (continuation of the phase coexistence curve in the supercritical region) is a characteristic thermodynamic element of the model. The investigation of the entropic forces between anisotropic particles has shown that the shape of the particle can induce directionality in the depletion interaction [1]. The fragmentary character of the resulting effective potential is a useful building block to initiate (self)assembly [3].
Direct connection between the change of self-diffusion coefficient of the water molecules in the suspensions of cell's membranes and its biomedical applications is discussed. Thermodynamics and dynamics of the two-state Bose-Hubbard model in the effective pseudospin representation. It is found that the order of the phase transition can change in the case µ >0 which becomes the first one.
First, we investigate the evolution of the Feigenbaum critical line in the system of two coupled H'enon maps [4] as the dispersion decreases. We also discuss the effects of an environmental quantum phase transition on the features of the two-qubit entanglement dynamics.

Our results for spin susceptibility and TDOS are extended to the presence of Zeeman splitting [2]. From the analysis of stability, the phase diagram of the model in the (pCO, pO2) parameter plane has been constructed.
Similarly, the linear response of the quadrupolar order parameter (Q) to the crystal field (∆), which is linearly related to the quadrupolar field in the Blume-Emery-Grifiths (BEG) model, can be interpreted as the quadrupolar susceptibility (χQ). In many methods for determining the ground states of lattice gas models (or equivalent spin models), the global ground state structures are constructed by local configurations of some subset of the lattice (cluster). This can be done in different ways depending on the position of the subcluster in the cluster.
