Embedding the sawtooth limit in a zigzag ladder of two coupled SU(2)_1 CFTs with extreme velocity ratio cancels the leading staggered interaction, leaving a marginal twist that collapses the apical spin velocity and causes energy-scale collapse independent of spatial correlation length.

Non-local interactions induce quantum-geometry-driven spin loop currents that lift degeneracies and open a full gap, realizing a topological Kondo insulator in MoTe2/WSe2 at ν=2.
An alternative open boundary condition in the Ising chain maps the system to two Kitaev chains, switching the topological degeneracy due to gauge dependence of the SSH winding number.
Ni doping in CeCoIn5 increases carrier density linearly as electron doping while suppressing anomalous enhancements in the Hall coefficient near the upper critical field and above Tc.
