Dear colleagues,

We are pleased to invite you to the SCL seminar of the Scientific 
Computing Laboratory, Center for the Study of Complex Systems,  which 
will be held on Thursday, 18 April 2019 at 14:00 in the library reading 
room “Dr. Dragan Popović" of the Institute of Physics Belgrade.

Mr. Miljan Dašić will present selected results from his Ph.D. thesis in 
a talk entitled

Modeling the behavior of confined dipolar configurations and ionic 
liquids

Abstract of the talk:

Self-assembly of hard spheres with permanent dipole moment under 
cylindrical confinement, (dipolar helices composed of dipolar hard 
spheres) has been investigated [1]. An approach for studying mesoscopic 
phenomena related to the lubrication with ionic liquids based on 
coarse-grained molecular dynamics simulations has been developed [2, 3, 
4]. Two generic models of ionic liquid, i.e., salt model (SM) [2, 3] and 
tailed model (TM) [4] have been implemented. The behavior of both bulk 
and confined ionic liquids has been carefully studied under static and 
dynamic conditions. The similarity of dipolar configurations and ionic 
liquids comes from the fact that their structure and behavior are 
governed by long-range interactions: dipole-dipole interaction (which is 
in addition anisotropic) and Coulombic interaction. Lekner method for 
summing the dipole-dipole interactions of 1D periodic structures has 
been applied for studying dipolar configurations, while MSM (multi-level 
summation) method for handling Coulombic interactions has been applied 
in the study of ionic liquids. A clear emergence of ordered structures 
(geometrically regular dipolar configurations and alternating ionic 
liquid layers) is a clear consequence of long-range interactions.
