Semiclassical asymptotics of a model problem

Mathematical Notes, 1993
The theory of semi-classical approximation, of differential operators in the last two decades has tackled using heavy geometrical theory. However, a good deal of detailed information has been available classically in low dimensional cases. Here, the authors discuss the semi-classical asymptotics of a differential operator \(H\) associated to the ...

Semiclassical asymptotics in magnetic Bloch bands

Journal of Physics A, 2002
Summary: This paper gives a simple construction of wave packets localized near semiclassical trajectories for an electron subject to external electric and magnetic fields. We assume that the magnetic and electric potentials are slowly varying perturbations of the potential of a constant magnetic field and a periodic lattice potential, respectively.

Semiclassical asymptotics of the Matrix Sturm-Liouville problem

Mathematical Notes, 2006
The authors consider the matrix Sturm-Liouville problem \[ (-ih\,d/dx)^2 y+A(x)y=Ey, \] where \(h\in[0,1)\) is a small parameter. They prove a new quantization condition for certain curves in the phase plane which intersect.

Semiclassical Spectral Asymptotics on Foliated Manifolds

Mathematische Nachrichten, 2002
The author considers a (hypo)elliptic pseudodifferential operator \(A_h\) on a closed foliated manifold \((M,{\mathcal F})\), depending on a parameter \(h> 0\), of the form \(A_h= A+ h^mB\), where \(A\) is a formally selfadjoint tangentially elliptic operator of order \(\mu> 0\) with the nonnegative principal symbol and \(B\) is a formally selfadjoint ...
