A general CFT model for antiferromagnetic spin-1/2 ladders with Mobius boundary conditions
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
We show how the low-energy properties of the 2-leg XXZ spin-1/2 ladders with general anisotropy parameter on closed geometries can be accounted for in the framework of the m-re…
Topologically protected qubits as minimal Josephson junction arrays with non trivial boundary conditions: a proposal
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
Recently a one-dimensional closed ladder of Josephson junctions has been studied (G. Cristofano et al., Phys. Lett. A 372 (2008) 2464) within a twisted conformal field theory (CFT)…
Correlation functions of the open XXZ chain II
N. Kitanine, K. Kozlowski, J. M. Maillet +3
We derive compact multiple integral formulas for several physical spin correlation functions in the semi-infinite XXZ chain with a longitudinal boundary magnetic field. Our formula…
Isomorphism of critical and off-critical operator spaces in two-dimensional quantum field theory
G. Delfino, G. Niccoli
For the simplest quantum field theory originating from a non-trivial fixed point of the renormalization group, the Lee-Yang model, we show that the operator space determined by the…
Correlation functions of the open XXZ chain I
N. Kitanine, K. K. Kozlowski, J. M. Maillet +3
We consider the XXZ spin chain with diagonal boundary conditions in the framework of algebraic Bethe Ansatz. Using the explicit computation of the scalar products of Bethe states a…
Transport properties in bilayer Quantum Hall systems in the presence of a topological defect
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
Following a suggestion given in Phys. Lett. B 571(2003) 621, we show how a bilayer Quantum Hall system at fillings nu =1/p+1 can exhibit a point-like topological defect in its edge…
