<｜begin▁of▁sentence｜>### Instruction:
Given the Condensed Matter collaborations graph from the year 2005, which is provided in a GML file named 'cond-mat-2005.gml', how can you use the 'lfm' function from the 'cdlib' library with an alpha value of 1.0 to perform community detection, and how can you output a JSON representation of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from GML file
G = nx.read_gml('cond-mat-2005.gml')

# Apply the LFM algorithm with alpha parameter to find communities
communities = algorithms.lfm(G, alpha=1.0)

# Generate a JSON representation of the communities
communities_json = communities.to_json()
print(communities_json)
