>VITAE:
Mario Ziman studied mathematical physics in Comenius University in Bratislava.
Currently he is working as a postdoc in the Research Center for Quantum
Information
in Bratislava in the group of prof. Vladimir Buzek. Mario Ziman is interested
in mathematical structures of quantum objects, conceptual questions of
quantum theory, quantum tomography, quantum dynamics and quantum communication. 

Abstract 


We will study two simple collision models describing decoherence
and socalled homogenization process (“exponential decay”).
After the specification of all possible interactions that corresponds
to such models we will discuss the entanglement behavior.
Altough the models are intrinsically discrete in time one can derive an
effective master equation. It turns out that arbitrary master equation
can be understand as a collison model.
