Conformal Invariance in Periodic Quantum Chains
We show how conformal invariance predicts the functional form of two-point correlators in one-dimensional periodic quantum systems. Numerical evidence for this functional form in a wide class of models — including long-ranged ones — is given and it is shown how this may be used to significantly speed up calculations of critical exponents. 05.70.Jk, 11.30.-j, 64.60.Fr Typeset using REVTEX
متن کاملChiral scale and conformal invariance in 2D quantum field theory.
It is well known that a local, unitary Poincaré-invariant 2D quantum field theory with a global scaling symmetry and a discrete non-negative spectrum of scaling dimensions necessarily has both a left and a right local conformal symmetry. In this Letter, we consider a chiral situation beginning with only a left global scaling symmetry and do not assume Lorentz invariance. We find that a left con...
متن کاملNon-Periodic Ising Quantum Chains and Conformal Invariance
In a recent paper, Luck [1] investigated the critical behaviour of one-dimensional Ising quantum chains with couplings constants modulated according to general non-periodic sequences. In this short note, we take a closer look at the case where the sequences are obtained from (two-letter) substitution rules and at the consequences of Luck’s results at criticality. They imply that only for a cert...
