Saturation Transition in the 1D ,-, Model,resents the traditional antiferromagnetic Heisenberg exchange and . is the strength of a competing four-spin interaction. Without external field, this system hosts a two-fold-degenerate dimerized (valence-bond solid) state above a critical value . ≈ 0.85 where . ≡ .∕.. The dimer order is destroyed a后天习得 发表于 2025-3-26 12:29:25
Saturation Transition in the 2D ,-, Model,ch the antiferromagnetic Heisenberg exchange (.) coupling competes with an additional four-spin interaction (.) that favors valence-bond solid order. For small values of ., the saturation transition is continuous and is expected to be governed by zero-scale-factor universality at its upper critical单挑 发表于 2025-3-26 15:22:11
Signatures of Deconfined Quantum Criticality in the 2D ,-,-, Model,on between the Néel antiferromagnet and the valence-bond solid in the .-. model is believed to be an example of such a deconfined quantum critical point where the excitations are spinons—bosons carrying spin-1/2. Using a magnetic field, one can induce a finite ground state density of magnetic excitaProjection 发表于 2025-3-26 20:46:48
