Dynamics of Bloch Electrons in Time Dependent External Electric Fields: Bounds for Interband Transitions
Alexandrina Nenciu
Using adiabatic expansions formalism, upper bounds for interband transitions for Bloch electrons in slowly varying in time electric fields are obtained. These bounds imply the vali…

Optimally localized Wannier functions for quasi one-dimensional nonperiodic insulators
H. D. Cornean, A. Nenciu, G. Nenciu
It is proved that for general, not necessarily periodic quasi one dimensional systems, the band position operator corresponding to an isolated part of the energy spectrum has discr…
