WebSep 19, 2024 · The quantum Ising chain for beginners. We present here various techniques to work with clean and disordered quantum Ising chains, for the benefit of students and non-experts. Starting from the Jordan-Wigner transformation, which maps spin-1/2 systems into fermionic ones, we review some of the basic approaches to deal with the … WebThe latter are known to diverge at the critical point as ∼1/p 2−η where p is the (d + 1)-dimensional momentum, η is defined to be the anomalous dimension of the order parameter (η = 1/4 for the quantum Ising chain). Knowing this, we can deduce the form of the quantum correlator in eqn [12] at the zero-temperature quantum critical point
