Dear Group Members,
Vladimir Stojanović from Basel is visiting Harvard this week and will
present a talk on Wednesday in our group. You can find his work on
http://quantumtheory.physik.unibas.ch/stojanovic/.
Here are the title and abstract of his talk:
When: Wednesday, 22 August, 2:00 pm
Where: Division Room
What: Talk by Vladimir Stojanović
Title: Polarons: from models to materials to quantum simulation
Abstract: After a brief introduction on the common electron-phonon
coupling mechanisms that may bring about polaronic behavior and
general conditions for the onset of such behavior, I will address
three recent developments. First, I will show an example of a
non-analytic behavior in a model with Peierls-type electron-phonon
coupling, breaking the long-held belief that polaron models never show
sharp transitions. Then I will present results of a recent study in
which we demonstrated that, contrary to what is often assumed, charge
carriers in crystalline organic semiconductors do not have polaronic
character. Finally, I will present some essential aspects of our
proposed trapped-ion based quantum simulation of the Holstein
molecular crystal model.
Best regards,
Sarah
