Lower bounds on the spatial decay of the ground state of the Pauli-Fierz model
Fumio Hiroshima, Yuki Tsujimoto
Lower bounds on the pointwise spatial decay of the ground state of the Pauli-Fierz model in non-relativistic quantum electrodynamics are studied. Two models are considered: the ful…
Strong-coupling asymptotics for anisotropic Rabi model
Masao Hirokawa, Fumio Hiroshima, DongYun Lee
The anisotropic quantum Rabi model provides a continuous interpolation between the quantum Rabi model and the Jaynes-Cummings model. In this paper, we study the norm-resolvent limi…
The weak coupling limit of the Pauli-Fierz model
Fumio Hiroshima
We investigate the weak coupling limit of the Pauli- Fierz Hamiltonian within a mathematically rigorous framework. Furthermore, we establish the asymptotic behavior of the effectiv…
Ground state degeneracy of the Pauli-Fierz Hamiltonian with spin
F. Hiroshima, H. Spohn
We consider an electron, spin 1/2, minimally coupled to the quantized radiation field in the nonrelativistic approximation, a situation defined by the Pauli-Fierz Hamiltonian .…
