Theta-vacuum and large N limit in CP^{N-1} sigma models
Miguel Aguado, Manuel Asorey
The theta dependence of the vacuum energy density in CP^{N-1} models is re-analysed in the semiclassical approach, the 1/N expansion and arguments based on the nodal structure of v…
A hierarchy of topological tensor network states
Oliver Buerschaper, Juan Martín Mombelli, Matthias Christandl +1
We present a hierarchy of quantum many-body states among which many examples of topological order can be identified by construction. We define these states in terms of a general, b…
Electric-magnetic duality of lattice systems with topological order
Oliver Buerschaper, Matthias Christandl, Liang Kong +1
We investigate the duality structure of quantum lattice systems with topological order, a collective order also appearing in fractional quantum Hall systems. We define electromagne…
Simulation of anyons with tensor network algorithms
Robert N. C. Pfeifer, Philippe Corboz, Oliver Buerschaper +3
Interacting systems of anyons pose a unique challenge to condensed matter simulations due to their non-trivial exchange statistics. These systems are of great interest as they have…
