Exact Diagonalization

filenames: ed_entropy_data_[#]_qubits.pkl

pickled list of dictionaries:

  • W
  • zero_energy_vec
  • reduced_dm
  • energy
  • renyi_entropy
  • vn_entropy

==========================================

For the spectrum data filenames: ed_spectrum_data_[#]_qubits.pkl.gz

to load:

  import pickle,gzip
  data = pickle.load(gzip.open("ed_spectrum_data_4_qubits.pkl.gz","rb"))

it contains a pickled list of lists of dicts (each list denotes a different W)

  • W
  • evals: eigenvalues
  • evecs: eigenvectors (v_i = evecs[:,i])
  • realization: disorder potential index, i.e. uses ith potential from q[#]_1000potentials.pkl

large spectrum data not uploaded due to file size

======

ed_entropyData_df.pkl.gz is a pickled pandas DataFrame with

  • E_order: energy eigenstate ordering
  • Energy: energy of the eigenstate
  • LA: L_A subsystem size cut
  • S1: Von Neumann entropy (1st Renyi entropy) of the L_A cut
  • S2: 2nd Renyi Entropy of the L_A cut
  • W: Disorder strength
  • realization: index of disorder in q[#]_1000potentials.pkl
