<｜begin▁of▁sentence｜>### Instruction:
Given the High-energy theory collaborations graph which you can read from a GML file named hep-th.gml, can you use Newman's leading eigenvector method in cdlib to perform community detection and then convert the resulting NodeClustering object into a JSON representation?
### Response:
import networkx as nx
from cdlib import algorithms

# Create a graph from the High-energy theory collaborations file
G = nx.read_gml('hep-th.gml')

# Apply Newman's leading eigenvector method for community detection
communities = algorithms.eigenvector(G)

# Exporting the NodeClustering object to a JSON
communities_json = communities.to_json()
print(communities_json)
