neuralqx.operators.holonomies module

This file contains the implementation of the U(1) holonomy operator

holonomy(H, site, adjoint=0, o_type='creation')

A method to create a NetKet operator that acts as the holonomy operator in U(1) theory on a given vertex. It can either be a creation or annihilation holonomy as well as an adjoint.

Parameters:

  • H (AbstractHilbertInterface) – the Hilbert space the operator acts on

  • site (int) – (int): the vertex it acts on in the graph

  • adjoint (int) – (int): an identifier to check if the adjoint of the operator is requested

  • o_type (str) – (String): an identifier to check the operation type (annihilation or creation)

  • is_4d – a flag to check if we are working in 4 spacetime dimensions

Return type:

LocalOperatorJax

Returns:

(netket.operator.LocalOperator): the holonomy operator on the given vertex
