Bound states in string nets
M. D. Schulz, S. Dusuel, J. Vidal
We discuss the emergence of bound states in the low-energy spectrum of the string-net Hamiltonian in the presence of a string tension. In the ladder geometry, we show that a single…
Mean-field ansatz for topological phases with string tension
S. Dusuel, J. Vidal
We propose a simple mean-field ansatz to study phase transitions from a topological phase to a trivial phase. We probe the efficiency of this approach by considering the string-net…
Ising anyons with a string tension
M. D. Schulz, S. Dusuel, G. Misguich +2
We consider the string-net model on the honeycomb lattice for Ising anyons in the presence of a string tension. This competing term induces a nontrivial dynamics of the non-Abelian…
Fate of Dirac Points in a Vortex Superlattice
M. Kamfor, S. Dusuel, K. P. Schmidt +1
We consider noninteracting fermions on the honeycomb lattice in the presence of a magnetic vortex superlattice. It is shown that depending on the superlattice periodicity, a gap ma…
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…
