Query: Jackiw-Teitelboim Model Coupled to Conformal Matter in the
  Semi-Classical Limit   We analyse the Jackiw-Teitelboim model of 2D gravity coupled to $N$ massless
free scalar fields in the semi-classical limit. Two systems are studied which
essentially differ in the boundary conditions that are imposed. We find that
the thermodynamics has interesting differences. We also analyse the response to
additional infalling matter which satisfies the null energy condition. The
second law is shown to be valid in both systems for the generalised entropy
which takes into account the entanglement across the event horizon due to the
matter fields. Similarly we find that the generalised entropy increases along
future Q-screens in both systems.
