Low-energy spectrum of Toeplitz operators with a miniwell
Alix Deleporte
In the semiclassical limit, it is well-known that the first eigenvector of a Toeplitz operator concentrates on the minimal set of the symbol. In this paper, we give a more precise…

Low-energy spectrum of Toeplitz operators: the case of wells
Alix Deleporte
In the 1980s, Helffer and Sjöstrand examined in a series of articles the concentration of the ground state of a Schrödinger operator in the semiclassical limit. In a similar spirit…
