ABSTRACT
We report thermoelectric measurements of the low carrier heavy fermion compound URu2Si2 at high fields up to 34T and temperatures down 500mK. The field dependence power (TEP) Nernst signal shows successive anomalies deep inside hidden order (HO) phase. position these correspond different changes in Shubnikov-de Haas frequencies effective masses around 12 T, 17 23 T 30 T. These results indicate reconstructions Fermi surface, which imply electronic phase transitions well within HO
