Query: Electric Field effects on quantum correlations in semiconductor quantum
  dots   We study the effect of external electric bias on the quantum correlations in
the array of optically excited coupled semiconductor quantum dots. The
correlations are characterized by the quantum discord and concurrence and are
observed using excitonic qubits. We employ the lower bound of concurrence for
thermal density matrix at different temperatures. The effect of the F\"orster
interaction on correlations will be studied. Our theoretical model detects
nonvanishing quantum discord when the electric field is on while concurrence
dies, ensuring the existence of nonclassical correlations as measured by the
quantum discord.
