Modelowanie ograniczeń architektury BHJ w fotoogniwach organicznych : wyniki wstępne

Wojtkiewicz J., Pilch M.

Elektronika : konstrukcje, technologie, zastosowania

2016

Vol. 57, nr 10

41--42

W artykule przedstawiono wyniki oszacowania wydajności ogniw fotowoltaicznych budowanych w architekturze BHJ, stanowiących wstęp do oszacowania tej wydajności w bardziej realnym modelu trójwymiarowym.

The article presents the results of assessment of photovoltaic panels efficiency in BHJ architecture, what poses an introduction to assessment of efficiency in three-dimensional model.

Monte Carlo Simulations of the Ising Model on GPU

Wojtkiewicz J., Kalinowski K.

Computational Methods in Science and Technology

2015

Vol. 21, No. 2

69--98

Monte Carlo simulations of two- and three-dimensional Ising model on graphic cards (GPU) are described. The standard Metropolis algorithm has been employed. In the framework of the implementation developed by us, simulations were up to 100 times faster than their sequential CPU analogons. It is possible to perform simulations for systems containing up to 109 spins on Tesla C2050 GPU. As a physical application, higher cumulants for the 3d Ising model have been calculated.

O modelu Hubbarda słów kilka

In this article basic definitions, facts, achievements, and open problems concerning the Hubbard model are briefly reviewed. We begin with the definition of the model accompanied by the sketch of its derivation from Schrodinger equation for interacting electrons in a periodic potential. Then we discuss some applications of the model to certain physical problems (antiferromagnetism, ferromagnetism, stripe phases in superconductors). We also review some important achievements of the field during the forty-years-old history of the Hubbard model as well as several open problems.
