Self-duality and bound states of the toric code model in a transverse field
J. Vidal, R. Thomale, K. P. Schmidt +1
We investigate the effect of a transverse magnetic field on the toric code model. We show that this problem can be mapped onto the Xu-Moore model and thus onto the quantum compass…

Low-energy effective theory of the toric code model in a parallel field
J. Vidal, S. Dusuel, K. P. Schmidt
We determine analytically the phase diagram of the toric code model in a parallel magnetic field which displays three distinct regions. Our study relies on two high-order perturbat…

Perturbative study of the Kitaev model with spontaneous time-reversal symmetry breaking
S. Dusuel, K. P. Schmidt, J. Vidal +1
We analyze the Kitaev model on the triangle-honeycomb lattice whose ground state has recently been shown to be a chiral spin liquid. We consider two perturbative expansions: the is…
