Lifetime of the Wannier {

چکیده
We consider the small eld asymptotics of the ladder lifetime for a single ladder model. Using the convergent perturbation series, we prove that the behavior of the lifetime computed by means of the Fermi Golden Rule is proportional to the correct one with the factor ? 3 2. The relation with usual adiabatic problems is brieey discussed.

Wannier-bloch Oscillators
We consider a Wannier-Stark problem for small eld f in the one-ladder case. We prove that a generical rst band state is a metastable state (Wannier-Bloch oscillator) with the lifetime determined by the imaginary part of the Wannier-Stark ladder. The innnite resonances of the ladder cause Bloch oscillations as a global beating eeect. For an adiabatic time = ft large enough, but much smaller than...
متن کاملLifetime of the Wannier-Stark resonances and perturbation theory
We consider the small field asymptotics of the ladder lifetime for a single ladder model. Using the convergent perturbation series, we prove that the behavior of the lifetime computed by means of the Fermi Golden Rule is proportional to the correct one with the factor ( π 3 )2 . The relation with usual adiabatic problems is briefly discussed.
متن کاملExponential localization of Wannier functions in insulators.
The exponential localization of Wannier functions in two or three dimensions is proven for all insulators that display time-reversal symmetry, settling a long-standing conjecture. Our proof relies on the equivalence between the existence of analytic quasi-Bloch functions and the nullity of the Chern numbers (or of the Hall current) for the system under consideration. The same equivalence implie...
متن کاملWannier representation of Z2 topological insulators
We consider the problem of constructing Wannier functions for Z2 topological insulators in two dimensions. It is well known that there is a topological obstruction to the construction of Wannier functions for Chern insulators, but it has been unclear whether this is also true for the Z2case. We consider the Kane-Mele tight-binding model, which exhibits both normal (Z2-even) and topological (Z2-...
متن کاملMaximally-localized Wannier functions in perovskites: Cubic BaTiO3
The electronic ground state of a periodic crystalline solid is usually described in terms of extended Bloch orbitals; localized Wannier functions can alternatively be used. These two representations are connected by families of unitary transformations, carrying a large degree of arbitrariness. We have developed a localization algorithm that allows one to iteratively transform the extended Bloch...
