Title: Floquet Topological Insulators? A few warnings

Abstract:
I will give an informal pre-Easter-holiday presentation of recent work, 
done
with Lorenzo Privitera (and also with Angelo Russomanno), on 
out-of-equilibrium
periodic driving of closed quantum systems (Floquet physics), which have 
overlap
with the field of ``topological quantum matter''. I will concentrate on 
two examples:
a periodically driven graphene [1] (which leads to the Haldane model 
physics)
and Thouless topological adiabatic pumping of a one-dimensional insulator
[3,4,5,6]. During the talk, I will try to stress a few non-equilibrium 
aspects that should
be kept in mind when thinking of ``Floquet Topological Insulators": 
this, to spell it
out, explains the "warnings" in the title.
