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…

Superconductor/Insulator Transition in the Striped Phase
Yu. Dimashko, C. Morais Smith
We study the transversal dynamics of a charged stripe (quantum string) at and show that its kink excitations play the role of current carriers. If the hopping amplitude …
