Witryna5 sty 2015 · They considered a “bath” of Ising spins and showed, theoretically, that the partition function of the bath under a complex magnetic field is equivalent to the quantum coherence of a probe spin coupled to the spin bath. (Quantum spin coherence is a measure of the extent to which a spin holds its orientation as time evolves.)

Results are presented for a Floquet Ising chain with duality twisted boundary conditions, taking into account the role of weak integrability breaking in the form of four-fermion interactions. In the integrable case, a single isolated Majorana zero mode exists which is a symmetry in … The most studied case of the Ising model is the translation-invariant ferromagnetic zero-field model on a d-dimensional lattice, namely, Λ = Z , Jij = 1, h = 0. No phase transition in one dimension In his 1924 PhD thesis, Ising solved the model for the d = 1 case, which can be thought of as a linear horizontal lattice … Zobacz więcej The Ising model (or Lenz-Ising model or Ising-Lenz model), named after the physicists Ernst Ising and Wilhelm Lenz, is a mathematical model of ferromagnetism in statistical mechanics.
