Point defect absorption by grain boundaries in -iron by atomic density function modeling

O. Kapikranian, H. Zapolsky, R. Patte +3

Using the atomic density function theory (ADFT), we examine the point defect absorption at [110] symmetrical tilt grain boundaries in body-centered cubic iron. It is found that the…

Atomic structure of grain boundaries in iron modeled using the atomic density function

O. Kapikranian, H. Zapolsky, Ch. Domain +4

A model based on the continuous atomic density function (ADF) approach is applied to predict the atomic structure of grain boundaries (GBs) in iron. Symmetrical [100] and [110] til…

Spin-spin correlation function of the 2D XY model with weak site or bond dilution

Oleksandr Kapikranian

The spin-spin correlation function of the 2D XY model decays as a power law at all temperatures below the Berezinskii-Kosterlitz-Thouless transition point with a temperature depend…

Interplay of topological and structural defects in the 2D XY model

Oleksandr Kapikranian, Bertrand Berche, Yurij Holovatch

The present work is devoted to the investigation of the interaction between vortices (topological defects) and site-impurities (structural defects) in the 2D XY model and its influ…

Perturbation expansion for the diluted two-dimensional XY model

Oleksandr Kapikranian, Bertrand Berche, Yurij Holovatch

We study the quasi-long-range ordered phase of a 2D XY model with quenched site-dilution using the spin-wave approximation and expansion in the parameter which characterizes the de…

Quasi-long-range ordering in a finite-size 2D Heisenberg model

Oleksandr Kapikranian, Bertrand Berche, Yurij Holovatch

We analyse the low-temperature behaviour of the Heisenberg model on a two-dimensional lattice of finite size. Presence of a residual magnetisation in a finite-size system enables u…
