On the adiabatic theorem when eigenvalues dive into the continuum
Horia D. Cornean, Arne Jensen, Hans Konrad Knörr +1
We consider a reduced two-channel model of an atom consisting of a quantum dot coupled to an open scattering channel described by a three-dimensional Laplacian. We are interested i…
Resolvent expansions for the Schrödinger operator on the discrete half-line
Kenichi Ito, Arne Jensen
Simplified models of transport in mesoscopic systems are often based on a small sample connected to a finite number of leads. The leads are often modelled using the Laplacian on th…
Branching form of the resolvent at threshold for multi-dimensional discrete Laplacians
Kenichi Ito, Arne Jensen
We consider the discrete Laplacian on , and compute asymptotic expansions of its resolvent around thresholds embedded in continuous spectrum as well as those at end po…
Wannier functions and Z_2 invariants in time-reversal symmetric topological insulators
Horia D. Cornean, Domenico Monaco, Stefan Teufel
We provide a constructive proof of exponentially localized Wannier functions and related Bloch frames in 1- and 2-dimensional time-reversal symmetric (TRS) topological insulators.…
