Effective action, magnetic excitations and quantum fluctuations in lightly doped single layer cuprates
Alexander I. Milstein, Oleg P. Sushkov
We consider the extended 2D model at zero temperature. Parameters of the model corresponds to doping by holes. Using the low doping effective action we demonstrate tha…
Screening of Coulomb Impurities in Graphene
Ivan S. Terekhov, Alexander I. Milstein, Valeri N. Kotov +1
We calculate exactly the vacuum polarization charge density in the field of a subcritical Coulomb impurity, , in graphene. Our analysis is based on the exact electron Green…
Spin effects in interaction and their possible use to polarize antiproton beams
V. F. Dmitriev, A. I. Milstein, V. M. Strakhovenko
Low energy interaction is considered taking into account the polarization of both particles. The corresponding cross sections are calculated using the Paris nucleon-antin…
Bremsstrahlung in alpha-Decay Reexamined
H. Boie, H. Scheit, U. D. Jentschura +5
A high-statistics measurement of bremsstrahlung emitted in the alpha decay of 210Po has been performed, which allows to follow the photon spectra up to energies of ~ 500 keV. The m…
Photon splitting in a laser field
A. Di Piazza, A. I. Milstein, C. H. Keitel
Photon splitting due to vacuum polarization in a laser field is considered. Using an operator technique, we derive the amplitudes for arbitrary strength, spectral content and polar…
Effective action of the weakly doped t-J model and spin-wave excitations in the spin-glass phase of La_{2-x}Sr_xCuO_4
Andreas Luscher, Alexander I. Milstein, Oleg P. Sushkov
We derive the low-energy effective field theory of the extended t-J model in the regime of light doping. The action includes a previously unknown Berry phase term, which is discuss…
