Exact solution of a spin-1/2 chain with three-site interactions in a random transverse field: Influence of randomness on quantum phase transition

Volodymyr Derzhko, Oleg Derzhko, Johannes Richter

We present exact results for the ground-state and thermodynamic properties of the spin-1/2 chain with three-site interactions in a random (Lorentzian) transverse field. We dis…
