On the energy growth of some periodically driven quantum systems with shrinking gaps in the spectrum
Pierre Duclos, Ondra Lev, Pavel Stovicek
We consider quantum Hamiltonians of the form H(t)=H+V(t) where the spectrum of H is semibounded and discrete, and the eigenvalues behave as E_n~n^α, with 0<α<1. In particular, the…
On the stability of periodically time-dependent quantum systems
Pierre Duclos, Eric Soccorsi, Pavel Stovicek +1
The main motivation of this article is to derive sufficient conditions for dynamical stability of periodically driven quantum systems described by a Hamiltonian H(t), i.e., conditi…
Adiabatically switched-on electrical bias in continuous systems, and the Landauer-Buttiker formula
Horia D. Cornean, Pierre Duclos, Gheorghe Nenciu +1
Consider a three dimensional system which looks like a cross-connected pipe system, i.e. a small sample coupled to a finite number of leads. We investigate the current running thro…
