Regularities of ground states of quantum field models
Asao Arai, Masao Hirokawa, Fumio Hiroshima
Regularities and higher order regularities of ground states of quantum field models are investigated through the fact that asymptotic annihilation operators vanish ground states. M…
Binding energy for hydrogen-like atoms in the Nelson model without cutoffs
Christian Hainzl, Masao Hirokawa, Herbert Spohn
In the Nelson model particles interact through a scalar massless field. For hydrogen-like atoms there is a nucleus of infinite mass and charge , , fixed at the origin an…
Infrared Catastrophe for Nelson's Model
Masao Hirokawa
We mathematically study the infrared catastrophe for the Hamiltonian of Nelson's model when it has the external potential in a general class. For the model, we prove the pull-throu…
Anomalous Pauli electron states for magnetic fields with tails
Pavel Exner, Masao Hirokawa, Osamu Ogurisu
We consider a two-dimensional electron with an anomalous magnetic moment, g>2, interacting with a nonzero magnetic field B perpendicular to the plane which gives rise to a flux F.…
