  We show that the combined effects of dynamical Coulomb blockade and integer
quantum Hall effect in a coupled hybrid metal-semiconductor setup provide a
pathway for realizing resonant tunneling in Luttinger liquids. This hybrid
setup can be brought to the quantum critical regime by varying gate voltages
and contact resistances. We explore the nature of quantum criticality, Kondo
effect, charge fractionalization and transport in such a hybrid setup, and
verify their robust non-Fermi liquid behaviors. Our work opens a promising
route for quantum simulating exotic zero temperature quantum critical phenomena
associated with Luttinger liquid physics in a nanoengineered electronic circuit
with well-defined quantum Hall channels.
