Spectroscopy of a topological phase
M. Kamfor, S. Dusuel, J. Vidal +1
Dynamical correlation functions of the toric code in a uniform magnetic field are studied inside the topological phase, in the small-field limit. Such an experimentally measurable…
Robustness of a perturbed topological phase
S. Dusuel, M. Kamfor, R. Orus +2
We investigate the stability of the topological phase of the toric code model in the presence of a uniform magnetic field by means of variational and high-order series expansion ap…
Kitaev model and dimer coverings on the honeycomb lattice
M. Kamfor, S. Dusuel, J. Vidal +1
We consider an extension of the Kitaev honeycomb model based on arbitrary dimer coverings satisfying matching rules. We focus on three different dimer coverings having the smallest…
Bound states in two-dimensional spin systems near the Ising limit: A quantum finite-lattice study
S. Dusuel, M. Kamfor, K. P. Schmidt +2
We analyze the properties of low-energy bound states in the transverse-field Ising model and in the XXZ model on the square lattice. To this end, we develop an optimized implementa…
