Abstract

Recently large Nernst effect and Seebeck effect were observed above the superconducting transition temperature 2.3 K in a heavy fermion superconductor CeCoIn,. We interpret this large Nemst effect in terms of unconventional density wave (UDW), which appears around T = 18 K. In the presence of magnetic field, Landau levels are formed in UDW, and the transport is dominated by thermally excited quasiparticles across the levels. Our theory describes successfully the available experimental data, and the deduced fitting parameters are in accordance with what is expected in the vicinity of a quantum critical point.
