Introvert

Conformal Invariance in the Ising Quantum Chain,eld theory in chapter 6, this example further illustrates the general machinery used for applying conformal invariance and useful insight will be obtained by comparing these two different approaches to the same problem.

The Hamiltonian Limit and Universality,s useful for numerical investigations. At the same time, we also show, in the context of the Ising model, that this way the universality between different model realizations of systems in the same universality class becomes explicit in yielding the same quantum Hamiltonian. For reviews, see [227, 177].

Numerical Techniques,eliably in the context of critical quantum chains and do not attempt to give a systematic overview on the numerous numerical algorithms which exist in the literature. These methods can be applied independently of the conformal invariance of the model, but throughout this chapter, we shall take . to be defined on a quantum . of . sites.

我不明白

Modular Invariance,just the 5 found can be realized. A part of the explanation comes from the locality requirement for the correlation functions discussed in chapters 5–7. A finer explanation for this selection comes from the requirement of . for the partition function. The presentation follows the work of Cardy [80, 81, G14].

Conformal Perturbation Theory,of these and shall show how finite-size corrections and finite-size scaling functions can be derived from the known operator content of a given model. These techniques do not require the integrability of the system under consideration.
