New Results on the Phase Diagram of the FFXY Model: A Twisted CFT Approach
G. Cristofano, V. Marotta, P. Minnhagen +2
The issue of the number, nature and sequence of phase transitions in the fully frustrated XY (FFXY) model is a highly non trivial one due to the complex interplay between its conti…
A conformal field theory description of magnetic flux fractionalization in Josephson junction ladders
G. Cristofano, V. Marotta, A. Naddeo +1
We show how the recently proposed effective theory for a Quantum Hall system at "paired states" filling v=1 (Mod. Phys. Lett. A 15 (2000) 1679; Nucl. Phys. B641 (2002) 547), the tw…
Twisted CFT and bilayer Quantum Hall systems
G. Cristofano, V. Marotta, A. Naddeo
We identify the impurity interactions of the recently proposed CFT description of a bilayer Quantum Hall system at filling nu =m/(pm+2) in Mod. Phys. Lett. A 15 (2000) 1679. Such a…
Paired states on a torus
G. Cristofano, G. Maiella, V. Marotta +1
We analyze the modular properties of the effective CFT description for paired states, proposed in cond-mat/0003453, corresponding to the non-standard filling nu =1/(p+1). We constr…
Tunnelling Effects in a Brane System and Quantum Hall Physics
L. Cappiello, G. Cristofano, G. Maiella +1
We argue that a system of interacting D-branes, generalizing a recent proposal, can be modelled as a Quantum Hall fluid. We show that tachyon condensation in such a system is equiv…
A conformal field theory description of the paired and parafermionic states in the quantum Hall effect
G. Cristofano, G. Maiella, V. Marotta
We extend the construction of the effective conformal field theory for the Jain hierarchical fillings proposed in cond-mat/9912287 to the description of a quantum Hall fluid at non…
