Abstract
We consider the effect of a local interatomic repulsion on synthetic heterostructures where a discrete synthetic dimension is created by Raman processes on top of $SU(N)$-symmetric two-dimensional lattice systems. At a filling of one fermion per site, increasing the interaction strength, the system is driven towards a Mott state which is adiabatically connected to a band insulator. The chiral currents associated with the synthetic magnetic field increase all the way to the Mott transition, where they reach the maximum value, and they remain finite in the whole insulating state. The transition towards the Mott-band insulator is associated with the opening of a gap within the low-energy quasiparticle peak, while a mean-field picture is recovered deep in the insulating state.
Author comments upon resubmission
thanks for sending us the reports of two Referees. We are grateful to the Referees for their careful, positive and constructive reports that helped us improving our manuscript.
We have indeed revised the manuscript complying with the requests of both Referees. Our detailed point-by-point response to the Referees has been uploaded.
In view of the already positive report of both Referees, and in view of the improvements that we have introduced in order to fully comply with the requests of both Referees, we are confident that this new version of our paper can be accepted for publication on SciPost Physics.
Best regards,
The authors

Report
The authors replied to my comments and to the comments of the second referee in a very precise and pertinent way, I have rarely seen such an in-depth reply! For this reason, the paper is definitely ready to be accepted for publication. I also have to say that I appreciate the new structure of the paper since I agree with the main comments of the second referee.
