The Langevin Equation for a Quantum Heat Bath
S. Attal, A. Joye
We compute the quantum Langevin equation (or quantum stochastic differential equation) representing the action of a quantum heat bath at thermal equilibrium on a simple quantum sys…
General Adiabatic Evolution with a Gap Condition
Alain Joye
We consider the adiabatic regime of two parameters evolution semigroups generated by linear operators that are analytic in time and satisfy the following gap condition for all time…
Accuracy on eigenvalues for a Schrodinger operator with a degenerate potential in the semi-classical limit
Abderemane Morame, Francoise Truc
We consider a semi-classical Schrodinger operator with a degenerate potential V(x,y) =f(x) g(y) . g is assumed to be a homogeneous positive function of m variables and f is a stric…
The width of resonances for slowly varying perturbations of one-dimensional periodic Schrödinger operators
Frédéric Klopp, Magali Marx
In this talk, we report on results about the width of the resonances for a slowly varying perturbation of a periodic operator. The study takes place in dimension one. The perturbat…
