Ising critical temperature
Witryna8 sty 2010 · If the 1D Ising chain is precisely at its critical point ( h = hC ), then the bound states stabilized by the additional longitudinal field hz morph into the “quantum resonances” that are a characteristic fingerprint of the emergent symmetries near the quantum critical point. Witryna13 gru 2024 · Actually, the 1D Ising chain in zero field does not have a finite-temperature phase transition. Instead it's disordered at all finite temperatures. However, there exists a critical point at T = 0. Share Cite Improve this answer Follow answered Dec 14, 2024 at 0:43 Anyon 4,451 1 13 40 Machine precision?
