Gapped spin liquid in the breathing kagome Heisenberg antiferromagnet
Mohsin Iqbal, Didier Poilblanc, Norbert Schuch
We investigate the spin-1/2 Heisenberg antiferromagnet on the kagome lattice with breathing anisotropy (i.e. with weak and strong triangular units), constructing an improved simple…
Topological Spin Liquids: Robustness under perturbations
Mohsin Iqbal, Helena Casademunt, Norbert Schuch
We study the robustness of the paradigmatic kagome Resonating Valence Bond (RVB) spin liquid and its orthogonal version, the quantum dimer model. The non-orthogonality of singlets…
Detecting subsystem symmetry protected topological order via entanglement entropy
David T. Stephen, Henrik Dreyer, Mohsin Iqbal +1
Subsystem symmetry protected topological (SSPT) order is a type of quantum order that is protected by symmetries acting on lower-dimensional subsystems of the entire system. In thi…
