On the scaling properties of (2+1) directed polymers in the high temperature limit
Victor Dotsenko, Boris Klumov
In this paper in terms of the replica method we consider the high temperature limit of (2+1) directed polymers in a random potential and propose an approach which allows to compute…

The two-body (pair) contribution to the entropy of two-dimensional Yukawa systems is calculated and analyzed. It is demonstrated that in the vicinity of the fluid-solid (freezing)…
Three-dimensional structure of a string-fluid complex plasma
M. Y. Pustylnik, B. Klumov, M. Rubin-Zuzic +12
Three-dimensional structure of complex (dusty) plasmas was investigated under long-term microgravity conditions in the International-Space-Station-based Plasmakristall-4 facility.…
Instantaneous shear modulus of Yukawa fluids across coupling regimes
Sergey Khrapak, Boris Klumov
The high frequency (instantaneous) shear modulus of three-dimensional Yukawa systems is evaluated in a wide parameter range, from the very weakly coupled gaseous state to the stron…

R. E. Ryltsev, B. A. Klumov, N. M. Chtchelkatchev +1
Special role in computer simulations of supercooled liquid and glasses is played by few general models representing certain classes of real glass-forming systems. Recently, it was…
Self-diffusion in single-component Yukawa fluids
Sergey Khrapak, Boris Klumov, Lenaic Couedel
It was suggested in the literature that the self-diffusion coefficient of simple fluids can be approximated as a ratio of the squared thermal velocity of the atoms to the "fluid Ei…

An approach to calculate high-frequency bulk and shear modului of two-dimensional (2D) weakly screened Yukawa fluids and solids is presented. Elastic moduli are directly related to…
Collective modes in simple melts: Transition from soft spheres to the hard sphere limit
Sergey Khrapak, Boris Klumov, Lenaic Couedel
We study collective modes in a classical system of particles with repulsive inverse-power-law (IPL) interactions in the fluid phase, near the fluid-solid coexistence (IPL melts). T…

R. E. Ryltsev, B. A. Klumov, N. M. Chtchelkatchev
For a three dimensional system we answer two questions, how simple a particle system might be to show the quasicrystal order and, what system features are the most important for qu…
