Non-relativistic Pauli--Fierz Hamiltonian for less than two photons

D. Dayantsolmon, A. Galtbayar

We consider the Pauli--Fierz model, which describes a particle (an electron) coupled to the quantized electromagnetic field and limit the number of photons to less than 2. By compu…

On the approximation by regular potentials of Schrödinger operators with point interactions

Artbazar Galtbayar, Kenji Yajima

We prove that the wave operators for Schrödinger operators with multi-center local point interactions are the scaling limits of the ones for Schrödinger operators with regular pote…
