  As a canonical response to the applied magnetic field, the electronic states
of a metal are fundamentally reorganized into Landau levels. In Dirac metals,
Landau levels can be expected without magnetic fields, provided that an
inhomogeneous strain is applied to spatially modulate electron hoppings in a
similar way as the Aharonov-Bohm phase. We here predict that a twisted zigzag
nanoribbon of graphene exhibits strain-induced pseudo Landau levels of
unexplored but analytically solvable dispersions at low energies. The presence
of such dispersive pseudo Landau levels results in a negative strain
resistivity characterizing the $(1+1)$-dimensional chiral anomaly if partially
filled and can greatly enhance the thermopower when fully filled.
