Kvantové Monte Carlo simulace elektronové struktury pevných látek

Tuesday, 04.02.2014 10:00 - 11:00

Jindřich Kolorenč (Oddělení teorie kondenzovaných látek, Fyzikální Ústav AV ČR, v.v.i.)

Na semináři budou popsány základní principy takzvané difuzní Monte Carlo metody, která umožňuje určovat vlastnosti základního stavu kvantových mnohočásticových systémù s velmi vysokou přesností. Jak název metody napovídá, transformace kvantové úlohy do podoby klasického stochastického procesu simulovatelného počítačem je postavena na podobnosti Schrödingerovy a difuzní rovnice. Difuzní Monte Carlo metoda nachází uplatnění při studiu elektronové struktury široké škály systémů, od konečných (atomů a molekul) až po rozlehlé (pevné látky).

Silicon nanocrystals, photonic structures and optical gain

Thursday, 06.02.2014 15:00 - 15:30

Lukáš Ondič (Department of Thin Films and Nanostructures, Institute of Physics, CAS)

In this talk, which is a public rehearsal of my PhD defense, I will present the main results of my doctoral work. First, I will discuss the origin of a fast blue-green luminescence band in silicon nanocrystals which was investigated by means of time-resolved spectroscopy at low helium temperatures. Second, I will give a brief introduction to the phenomenon of light extraction employing leaky modes of photonic crystals.
