Query: A General Charge Transport Picture for Organic Semiconductors with
  Nonlocal Electron-Phonon Couplings   The nonlocal electron-phonon couplings in organic semiconductors responsible
for the fluctuation of intermolecular transfer integrals has been the center of
interest recently. Several irreconcilable scenarios coexist for the description
of the nonlocal electron-phonon coupling, such as phonon-assisted transport,
transient localization, and band-like transport. Through a nearly exact
numerical study for the carrier mobility of the Holstein-Peierls model using
the matrix product states approach, we locate the phonon-assisted transport,
transient localization and band-like regimes as a function of the transfer
integral ($V$) and the nonlocal electron-phonon couplings ($\Delta V$), and
their distinct transport behaviors are analyzed by carrier mobility, mean free
path, optical conductivity and one-particle spectral function. We also identify
an "intermediate regime" where none of the established pictures applies, and
the generally perceived hopping regime is found to be at a very limited end in
the proposed regime paradigm.
