Aperiodic Ising model on the Bethe lattice: Exact results
F. Igloi, L. Turban
We consider the Ising model on the Bethe lattice with aperiodic modulation of the couplings, which has been studied numerically in Phys. Rev. E 77, 041113 (2008). Here we present a…
Networks of quantum nanorings: programmable spintronic devices
Peter Foldi, Orsolya Kalman, Mihaly G. Benedict +1
An array of quantum rings with local (ring by ring) modulation of the spin orbit interaction (SOI) can lead to novel effects in spin state transformation of electrons. It is shown…
Evolution of the correlation functions in 2D dislocation systems
Péter Dusán Ispánovity, István Groma, Géza Györgyi
In this paper spatial correlations of parallel edge dislocations are studied. After closing a hierarchy of equations for the many-particle density functions by the Kirkwood superpo…
Counterterm resummation for 2PI-approximation in constant background
A. Patkos, Zs. Szep
Explicit counterterm construction is presented in a symmetry breaking background for the 2PI effective action of the self-interacting one-component scalar field including skeleton…
The Role of the Exchange Interaction in the One-Dimensional -Component Hubbard Model
E. Szirmai, Ö. Legeza, J. Sólyom
The commensurate -filled -component Hubbard chain was investigated by bosonization and high-precision density-matrix renormalization-group analysis. It was found that depen…
Variational wave functions for homogenous Bose systems
Andras Suto, Peter Szepfalusy
We study variational wave functions of the product form, factorizing according to the wave vectors k, for the ground state of a system of bosons interacting via positive pair inter…
