Spectral asymptotics for large skew-symmetric perturbations of the harmonic oscillator
I. Gallagher, Th. Gallay, F. Nier
Originally motivated by a stability problem in Fluid Mechanics, we study the spectral and pseudospectral properties of the differential operator $H_ε= -\partial_x^2 + x^2 + iε^{-1}…

Mean field limit for bosons and infinite dimensional phase-space analysis
Ammari Zied, Nier Francis
This article proposes the construction of Wigner measures in the infinite dimensional bosonic quantum field theory, with applications to the derivation of the mean field dynamics.…
