Spectral theory for one-body Stark operators
T. Adachi, K. Itakura, K. Ito +1
We investigate spectral theory for a large class of one-body Stark Hamiltonians using a commutator technique. Our results include Rellich's theorem, the limiting absorption princip…

On the Mourre estimates for three-body Floquet Hamiltonians
Tadayoshi Adachi
In this paper, we consider the Floquet Hamiltonian associated with a three-body Schrödinger operator with time-periodic pair potentials . By introducing a conjugate opera…

New methods in spectral theory of -body Schrödinger operators
T. Adachi, K. Itakura, K. Ito +1
We develop a new scheme of proofs for spectral theory of the -body Schrödinger operators, reproducing and extending a series of sharp results under minimum conditions. Our main…
