type: class

class tenpy.models.model.Model(lattice)[source]¶

Bases: object

Base class for all models.

The common base to all models is the underlying Hilbert space and geometry, specified by a Lattice.

Parameters

latticeLattice: The lattice defining the geometry and the local Hilbert space(s).

Attributes

latLattice: The lattice defining the geometry and the local Hilbert space(s).

Methods

group_sites(self[, n, grouped_sites])

Modify self in place to group sites.

group_sites(self, n=2, grouped_sites=None)[source]¶

Modify self in place to group sites.

Group each n sites together using the GroupedSite. This might allow to do TEBD with a Trotter decomposition, or help the convergence of DMRG (in case of too long range interactions).

This has to be done after finishing initialization and can not be reverted.

Parameters

nint: Number of sites to be grouped together.
grouped_sitesNone | list of GroupedSite: The sites grouped together.

Returns

grouped_siteslist of GroupedSite: The sites grouped together.
