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…
Fully frustrated Josephson junction ladders with Mobius boundary conditions as topologically protected qubits
Gerardo Cristofano, Vincenzo Marotta, Adele Naddeo +1
We show how to realize a ``protected'' qubit by using a fully frustrated Josephson Junction ladder (JJL) with Mobius boundary conditions. Such a system has been recently studied wi…
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…
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…
