We investigate roughening transitions in the context of transverse-field Ising models. As a modification of the transverse Ising model with short range interactions, which has been shown to exhibit domain wall roughening, we have looked into the possibility of a roughening transition for the case ...

We consider the random transverse-field Ising model in d = 3 dimensions with long-range ferromagnetic interactions which decay as a power α > d with the distance. Using a variant of the strong-disorder renormalization group method we study numerically the phase-transition point from the paramagne...
Ising Model with a Transverse Field The phase transition in the Ising model has been studied as a function of an applied transverse field, by Green's function and series-expansion methods. The critical indices are probably independent of the applied field except at T=0 whe... RJ Elliott,P ...
The one-dimensional transverse field Ising model is solved by continuous unitary transformations in the high-field limit. A high accuracy is reached due to the closure of the relevant algebra of operators, which we call string operators. The closure is related to the possibility to map the model...
