  • We use the coupled 2d-spin-3d-fermion model proposed by Rosch {\sl et. al.} (Phys. Rev. Lett. {\bf 79}, 159 (1997)) to study the thermoelectric behaviour of a heavy fermion compound when it is close to an antiferromagnetic quantum critical point. When the low energy spin fluctuations are quasi two dimensional, as has been observed in ${\rm YbRh}_2{\rm Si}_2$ and $ {\rm CeCu}_{6-x}{\rm Au}_x $, with a typical 2d ordering wavevector and 3d Fermi surface, the ``hot'' regions on the Fermi surface… CONTINUE READING
