Effective Field and the Bloch-Siegert Shift at Bihromatic Excitation of Multiphoton EPR
A. P. Saiko, G. G. Fedoruk, S. A. Markevich
The dynamics of multiphoton transitions in a two-level spin system excited by transverse microwave and longitudinal RF fields with the frequencies w_{mw} and w_{rf}, respectively,…
On a relation between Liouville field theory and a two component scalar field theory passing through the random walk
Franco Ferrari, Jaroslaw Paturej
In this work it is proposed a transformation which is useful in order to simplify non-polynomial potentials given in the form of an exponential. As an application, it is shown that…
A path integral approach to the dynamics of random chains
Franco Ferrari, Jaroslaw Paturej, Thomas A. Vilgis
In this work the dynamics of a freely jointed random chain with small masses attached to the joints is studied from a microscopic point of view. The chain is treated using a string…
Nielsen number is a knot invariant
Alexander Fel'shtyn
We show that the Nielsen number of a map is a knot invariant via representation variety
A twisted Burnside theorem for countable groups and Reidemeister numbers
Alexander Fel'shtyn, Evgenij Troitsky
The purpose of the present paper is to prove for finitely generated groups of type I the following conjecture of A.Fel'shtyn and R.Hill, which is a generalization of the classical…
Quantum phantom cosmology
Mariusz P. Dabrowski, Claus Kiefer, Barbara Sandhoefer
We apply the formalism of quantum cosmology to models containing a phantom field. Three models are discussed explicitly: a toy model, a model with an exponential phantom potential,…
