[Nenad Vukmirović]

Поштоване колегинице и колеге,

Позивам вас на семинар Лабораторије за примену рачунара у науци који ће 
у понедељак 23. децембра 2013. године у 14:00 у читаоници Института за 
физику одржати Златко Папић (Perimeter Institute for Theoretical 
Physics, Waterloo, Canada) поводом предстојећег избора у звање виши 
научни сарадник. Наслов семинара је:

Entanglement in topological phases and interacting quantum disordered 
systems

Abstract:

Though it was recognized early on as one of the fundamental aspects of 
quantum mechanics, entanglement has played an increasingly important 
role in condensed matter physics as well, in particular due to the fact 
that it underlies the recent ``tensor network" description of many-body 
systems, and through its practical uses as a resource for quantum 
computing. In this talk I will illustrate the profound role of the 
entanglement in two, rather different, types of physical systems: the 
topological phases arising in the context of the fractional quantum Hall 
effect, and the quantum disordered systems in a ``many-body localized" 
phase. I will show that the entanglement provides a way to understand 
the structure of the topologically-ordered ground states via a direct 
link between conformal field theory, solvable models, and the 
``matrix-product state" formalism. Furthermore, I will demonstrate that 
the entanglement also provides specific signatures for the 
non-equilibrium dynamics of disordered systems and determines the nature 
of the eigenstates in the ``many-body localized phase", which may have 
important consequences for controlling the coherence of isolated quantum 
systems in experiment.

Срдачно,
