Query: Correlation between lasing and transport properties in a quantum
  dot-resonator system   We study a double quantum dot system coherently coupled to an electromagnetic
resonator. By suitably biasing the system, a population inversion can be
created between the dot levels. The resulting lasing state exists within a
narrow resonance window, where the transport current correlates with the lasing
state. It allows probing the lasing state via a current measurement. Moreover,
the resulting narrow current peak opens perspective for applications of the
setup for high resolution measurements.
