Abstract Motivated by the goal to give the simplest possible microscopic foundation for a broad class of topological phases, we study quantum mechanical lattice models where the topology of the lattice is one of the dynamical variables. However, a fluctuating geometry can remove the separation between the system size and the range of local interactions, which is important for topological protection and ultimately the stability of a topological phase. In particular, it can open the door to a…

Detecting topological entanglement entropy in a lattice of quantum harmonic oscillators
The Kitaev surface code model is the most studied example of a topologically ordered phase and typically involves four-spin interactions on a two-dimensional surface. A universal signature of this


A Magnetic Model with a Possible Chern-Simons Phase
Abstract: An elementary family of local Hamiltonians , is described for a 2-dimensional quantum mechanical system of spin particles. On the torus, the ground state space Gŝ,ℓ is (log) extensively
String-net condensation: A physical mechanism for topological phases
We show that quantum systems of extended objects naturally give rise to a large class of exotic phases---namely topological phases. These phases occur when extended objects, called ``string-nets,''
From String Nets to Nonabelions
We discuss Hilbert spaces spanned by the set of string nets, i.e. trivalent graphs, on a lattice. We suggest some routes by which such a Hilbert space could be the low-energy subspace of a model of
Anyons in an exactly solved model and beyond
A spin-1/2 system on a honeycomb lattice is studied. The interactions between nearest neighbors are of XX, YY or ZZ type, depending on the direction of the link; different types of interactions may
A Topological Phase in a Quantum Gravity Model
I would claim that we do not have a suitably general definition of what a topological phase is, or more importantly, any robust understanding of how to enter one even in the world of mathematical
Lieb-Schultz-Mattis theorem for quasitopological systems
In this paper we address the question of the existence of a spectral gap in a class of local Hamiltonians. These Hamiltonians have the following properties: their ground states are known exactly; all
State sum invariants of 3 manifolds and quantum 6j symbols
IN THE 1980s the topology of low dimensional manifolds has experienced the most remarkable intervention of ideas developed in rather distant areas of mathematics. In the 4dimensional topology this
Non-perturbative Lorentzian Quantum Gravity, Causality and Topology Change
Abstract We formulate a non-perturbative lattice model of two-dimensional Lorentzian quantum gravity by performing the path integral over geometries with a causal structure. The model can be solved
Line of critical points in 2+1 dimensions: quantum critical loop gases and non-Abelian gauge theory.
A one-parameter family of lattice models of interacting spins is constructed, obtained their exact ground states, and its one-loop beta function vanishes for all values of the coupling constant, implying that it is also on a critical line.
Local interactions and non-abelian quantum loop gases.
Perturbing a local, gapless Hamiltonian with an anticipated "non-Abelian" ground-state wave function immediately drives the system into the Abelian phase, as can be seen by measuring the Hausdorff dimension of loops.
