Abstract
The authors use thermoelectric power and Hall-effect measurements to give evidence of a magnetic field-induced Fermi surface reconstruction in the heavy fermion superconductor UTe${}_{2}$ at the metamagnetic transition, which coincides with the abrupt suppression of superconductivity at 35 T for magnetic field applied along the hard magnetization axis.
