Analysis of quantum spin models on hyperbolic lattices and Bethe lattice
Michal Daniska, Andrej Gendiar
The quantum XY, Heisenberg, and transverse field Ising models on hyperbolic lattices are studied by means of the Tensor Product Variational Formulation algorithm. The lattices are…
Tensor product variational formulation applied to pentagonal lattice
Michal Daniška, Andrej Gendiar
The uniform two-dimensional variational tensor product state is applied to the transverse-field Ising, XY, and Heisenberg models on a regular hyperbolic lattice surface. The lattic…
Mean-field universality class induced by weak hyperbolic curvatures
Andrej Gendiar, Michal Daniska, Roman Krcmar +1
Order-disorder phase transition of the ferromagnetic Ising model is investigated on a series of two-dimensional lattices that have negative Gaussian curvatures. Exceptional lattice…
Weak correlation effects in the Ising model on triangular-tiled hyperbolic lattices
Andrej Gendiar, Roman Krcmar, Sabine Andergassen +2
The Ising model is studied on a series of hyperbolic two-dimensional lattices which are formed by tessellation of triangles on negatively curved surfaces. In order to treat the hyp…
Suppression of finite-size effects in one-dimensional correlated systems
A. Gendiar, M. Daniska, Y. Lee +1
We investigate the effect of a non-uniform deformation applied to one-dimensional (1D) quantum systems, where the local energy scale is proportional to de…
