When a second-order magnetic phase transition is tuned to zero temperature by nonthermal parameter, quantum fluctuations are critically enhanced, often leading the emergence of unconventional superconductivity. In these “quantum critical” superconductors it has been widely reported that normal-state properties above superconducting T c exhibit anomalous non-Fermi liquid behaviors and enhanced electron correlations. However, effect strong critical on condensate below less well established....

We report the Nernst effect ($\ensuremath{\nu}$) and thermoelectric power ($S$) data for Ce${}_{2}$PdIn${}_{8}$ heavy-fermion compound. Both $S$ $\ensuremath{\nu}$ behave anomalously at low temperatures: The thermopower shows a Kondo-like maximum $T=37$ K, while coefficient becomes greatly enhanced field dependent below $T\ensuremath{\approx}30$ K. In zero-$T$ limit $S/T$ $\ensuremath{\nu}/T$ diverge logarithmically, which can be related to occurrence of quantum critical point (QCP)....
