A Short Remark on the Polaron in the Semi-relativistic Pauli-Fierz Model
Itaru Sasaki
We consider the polaron of the spinless semi-relativistic Pauli-Fierz model. The Hamiltonian of the model is defined by $H(\mathbf{P}) = \sqrt{(\mathbf{P}-dΓ(\mathbf{k}) + e\bA)^2…
One Particle Binding of Many-Particle Semi-Relativistic Pauli-Fierz Model
Itaru Sasaki
It is shown that at least one particle is bound in the -particle semi-relativistic Pauli-Fierz model with negative potential $V(\bx)$. It is assumed that the particles have no s…
Note on the spectrum of discrete Schrödinger operators
Fumio Hiroshima, Itaru Sasaki, Tomoyuki Shirai +1
The spectrum of discrete Schrödinger operator on the -dimensional lattice is considered, where denotes the discrete Laplacian and a delta function with mass at a s…
Boltzmann limit and quasifreeness for a homogenous Fermi gas in a weakly disordered random medium
Thomas Chen, Itaru Sasaki
We discuss some basic aspects of the dynamics of a homogenous Fermi gas in a weak random potential, under negligence of the particle pair interactions. We derive the kinetic scalin…
Enhanced binding for N-particle system interacting with a scalar bose field I
Fumio Hiroshima, Itaru Sasaki
An enhanced binding of an -particle system interacting through a scalar bose field is investigated, where . It is not assumed that this system has a ground state for a…
