On a dual model for 5f electrons
D. V. Efremov, N. Hasselmann, E. Runge +2
We study the effect of intra-atomic correlations on anisotropies of hopping of 5f electrons. It is shown that they may considerably enhance these anisotropies to the extend that el…

Stripe dynamics in presence of disorder and lattice potentials
C. Morais Smith, N. Hasselmann, Yu. A. Dimashko +1
We study the influence of disorder and lattice pinning on the dynamics of a charged stripe. Starting from a phenomenological model of a discrete quantum string, we determine the ph…

The Striped Phase in Presence of Disorder and Lattice Potentials
N. Hasselmann, A. H. Castro Neto, C. Morais Smith +1
We study the influence of disorder and lattice effects on the striped phase and the incommensurate spin fluctuations of the cuprates and nickelates. Starting from a phenomenologica…
