Query: Robust Majorana signature detection with a coupled quantum
  dot-nanomechanical resonator in all-optical domain   Motivated by a recent experiment [Nadj-Perge et al., Science 346, 602 (2014)]
providing evidence for Majorana zero modes in iron chains on the
superconducting Pb surface, in the present work, we theoretically propose an
all-optical scheme to detect Majorana fermions, which is very different from
the current tunneling measurement based on electrical means. The optical
detection proposal consists of a quantum dot embedded in a nanomechanical
resonator with optical pump-probe technology. With the optical means, the
signal in the coherent optical spectrum presents a distinct signature for the
existence of Majorana fermions in the end of iron chains. Further, the
vibration of the nanomechanical resonator behaving as a phonon cavity will
enhance the exciton resonance spectrum, which makes the Majorana fermions more
sensitive to be detectable. This optical scheme affords a potential supplement
for detection of Majorana fermions and supports to use Majorana fermions in Fe
chains as qubits for potential applications in quantum computing devices.
