Spectral analysis of an abstract pair interaction model

Keisuke Asahara, Daiju Funakawa

We consider an abstract pair-interaction model in quantum field theory with a coupling constant λ∈R and analyze the Hamiltonian H(λ) of the model. In the massive c…

Localization for a one-dimensional split-step quantum walk with bound states robust against perturbations

Toru Fuda, Daiju Funakawa, Akito Suzuki

For given two unitary and self-adjoint operators on a Hilbert space, a spectral mapping theorem was proved in \cite{HiSeSu}. In this paper, as an application of the spectral mappin…

Weak limit theorem for a one-dimensional split-step quantum walk

Toru Fuda, Daiju Funakawa, Akito Suzuki

This paper proves a weak limit theorem for a one-dimensional split-step quantum walk and investigates the limit density function. In the density function, the difference between tw…
