Holomorphic extension of the de Gennes function
Virginie Bonnaillie-Noël, Frédéric Hérau, Nicolas Raymond
This note is devoted to prove that the de Gennes function has a holomorphic extension on a strip containing the real axis.
On spectral properties of the Bloch-Torrey operator in two dimensions
D. S. Grebenkov, B. Helffer
We investigate a two-dimensional Schrödinger operator, , with a purely complex potential . A rigorous definition of this non-selfadjoint operator is provided f…
Low lying spectral gaps induced by slowly varying magnetic fields
Horia D. Cornean, Bernard Helffer, Radu Purice
We consider a periodic Schrödinger operator in two dimensions perturbed by a weak magnetic field whose intensity slowly varies around a positive mean. We show in great generality t…
Pleijel's theorem for Schrödinger operators with radial potentials
Philippe Charron, Bernard Helffer, Thomas Hoffmann-Ostenhof
In 1956 . Pleijel gave his celebrated theorem showing that the inequality in Courant's theorem on the number of nodal domains is strict for large eigenvalues of the Laplacian. T…
