## Collective effects and liquid–glass transition in supercooled melts of binary alloys

Journal of Physics: Conference Series. 2019. Vol. 1147. P. 012015.

A possibility of a transition into a glassy state of binary alloys based on aluminum, nickel, and copper after ultrafast cooling has been investigated using the method of molecular dynamics. It was demonstrated that some 4-point correlators changed their behavior and depended on the parameters of the metastable alloy state. By analyzing the complex dynamics of particle motion in overcooled liquids some certain conditions for the formation of the glass for aluminum–nickel melt was founded.

The previously discovered features of the temperature behaviour of four-point spatial correlators allow us to study transitions to metastable states. Similar integral characteristics simultaneously study microscopic effects (vortex formation and clustering) and the effect of these phenomena on the thermodynamics of the whole system. It is shown that spatial and temporal behaviour of correlators in ...

It is shown that a sharp increase in viscosity, a change in the decay rate of correlations, and the appearance
of nonequilibrium and transverse sound in a thin film of aluminum melt during rapid cooling occur in the
same temperature range. The analysis is performed using the shear stress autocorrelation functions calculated by the molecular dynamics method. ...

We present a molecular dynamics (MD) study of size effect on the crystal nuclei geometry, formation and growth in supercooled tantalum film. The process is studied in a set of MD trajectories that are obtained by ultrafast cooling from the stable liquid phase to the temperature below the glass transition temperature. We describe the nucleation ...

In this study, the glass transition criteria based on the viscosity change and on the transverse sound propagation, that were obtained for the aluminum melt, are validated on the aluminum–copper film. Molecular dynamics method is used to study the isobaric cooling process. The glass transition temperature is estimated from the dependence of the oscillation damping ...

The problem of planar oscillations of a pendulum with variable length suspended on the Moon’s surface is considered. It is assumed that the Earth and Moon (or, in the general case, a planet and its satellite, or an asteroid and a spacecraft) revolve around the common center of mass in unperturbed elliptical Keplerian orbits. We ...

We investigate the time evolution of the momentum of an impurity atom injected into a degenerate Tonks-Girardeau gas. We establish that given an initial momentum p0 the impurity relaxes to a steady state with a nonvanishing momentum p∞. The nature of the steady state is found to depend drastically on whether the masses of the impurity and the host ...

Warm dense hydrogen is studied in the region of fluid–fluid phase transition within
the framework of the density functional theory. We report a procedure of obtaining
metastable states and calculate the equation of state. Metastable states are diagnosed by pair correlation functions and values of conductivity. We obtain a strong
overlapping through the density of metastable and equilibrium ...

We simulate the oscillation of the viscous drop in the viscous liquid. We combine methods of chromodynamics model and Shan-Chen pseudo-potential for the immiscible fluids. We measure the frequency of the first nontrivial eigenmode using the initial ellipsoid form of the drop. Drop oscillates about the equilibrium spherical form of radius $R$. Computed frequency as ...

We consider a spatially distributed evolutionary game based on the Prisoner’s
Dilemma with agents arranged on a three-dimensional simple cubic lattice. Comparing to twodimensional arrangements, we find that the larger number of neighbors favors the formation of
spatial chaos: the steady state of the game is chaotic unless the payoff parameter is small. ...

The exciton valley dynamics in van der Waals heterostructures with transition metal dichalcogenide monolayers is driven by the long-range exchange interaction between the electron and the hole in the exciton. It couples the states active in the opposite circular polarizations resulting in the longitudinal-transverse splitting of excitons propagating in the monolayer plane. Here we study ...

The proof of the security of quantum key distribution is a rather complex problem. Security is
defined in terms different from the requirements imposed on keys in classical cryptography. In quantum
cryptography, the security of keys is expressed in terms of the closeness of the quantum state of an eavesdropper
after key distribution to an ideal quantum state ...

It is often suggested that inter-particle distance in stable dusty plasma structures decreases with cooling as a square root of neutral gas temperature. Deviations from this dependence (up to the increase at cryogenic temperatures) found in the experimental results for the pressures range 0.1–8.0 mbar and for the currents range 0.1–1.0 mA are given. Inter-particle ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...
