It is shown that a strong magnetic field applied to a bulk metal
induces a Luttinger-liquid phase. This phase is characterized
by the zero-bias anomaly in tunneling:
the tunneling conductance scales as a power law of voltage
or temperature. The tunneling exponent increases with the magnetic
field as . The zero-bias anomaly is most pronounced
for tunneling with the field applied perpendicular to the plane of the
tunneling junction.
