Long-Time Dynamics of KdV Solitary Waves over a Variable Bottom
S. I. Dejak, I. M. Sigal
We study the variable bottom generalized Korteweg-de Vries (bKdV) equation dt u=-dx(dx^2 u+f(u)-b(t,x)u), where f is a nonlinearity and b is a small, bounded and slowly varying fun…

Ionization of Atoms in a Thermal Field
Jürg Fröhlich, Marco Merkli, Israel Michael Sigal
We study the stationary states of a quantum mechanical system describing an atom coupled to black-body radiation at positive temperature. The stationary states of the non-interacti…
