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…
The m-reduction in Conformal Field Theory as the Morita equivalence on two-tori
Vincenzo Marotta, Adele Naddeo
We study the Morita equivalence for field theories on noncommutative two-tori. For rational values of the noncommutativity parameter (in appropriate units) we show the equivale…
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)…
