hamiltonians.TFI

class zyglrox.core.hamiltonians.TFI(topology: Union[dict, str], g: float = 1.0, **kwargs)

The transverse field Ising-model is given by the Hamiltonian

\[H = -\sum_{<i,j>}^N \sigma_{i}^{z}\sigma_{j}^{z} - g \sum_{i}^N \sigma_{i}^{x}\]

with \(N\) the number of spins. This function takes kwargs L and M that can be used to specify the size of the standard topologies [‘line’, ‘rect_lattice’].

Args:

topology (dict, str):

A dict with nodes as keys and a list of edges as values or a string defining a standard topology

g (float):

order parameter for the transverse field Ising-model

**kwargs:

Additional arguments.

Returns (inplace):

None
