Local Response Topological Order External Perturbation

We study the behavior of the Re ′nyi entropies for the toric code subject to a variety of different perturbations, by means of 2D density matrix renormalization group and analytical methods. We find t...

Direct Probe Topological Order Cold Atoms
2016/1/22
Cold-atom experiments in optical lattices offer a versatile platform to realize various topological quantum phases. A key challenge in those experiments is to unambiguously probe the topological order...
Topological or deconfined phases are characterized by emergent, weakly fluctuating, gauge fields. In condensed matter settings they inevitably come coupled to excitations that carry the corresponding ...

We explore the possibility of inducing a topological insulator phase in a honeycomb lattice using a metallic gate. We start with a lattice model which does not include spin-orbit interaction. A metall...

Topological or deconfined phases are characterized by emergent, weakly fluctuating, gauge fields. In condensed matter settings they inevitably come coupled to excitations that carry the corresponding ...
We examine the onset of classical topological order in a nearest-neighbor kagome ice model. Using Monte Carlo simulations, we characterize the topological sectors of the groundstate using a non-local ...
