The thermopower as a fingerprint of the Kondo breakdown quantum critical point
K. -S. Kim, C. Pepin
We propose that the thermoelectric power distinguishes two competing scenarios for quantum phase transitions in heavy fermions : the spin-density-wave (SDW) theory and breakdown of…
Quantum Boltzman equation study for the Kondo breakdown quantum critical point
K. -S. Kim, C. Pepin
We develop the quantum Boltzman equation approach for the Kondo breakdown quantum critical point, involved with two bands for conduction electrons and localized fermions. Particula…
Luttinger-Ward functional approach in the Eliashberg framework : A systematic derivation of scaling for thermodynamics near a quantum critical point
A. Benlagra, K. -S. Kim, C. Pépin
Scaling expressions for the free energy are derived, using the Luttinger-Ward (LW) functional approach in the Eliashberg framework, for two different models of quantum critical poi…
Violation of Wiedemann-Franz law at the Kondo breakdown quantum critical point
K. -S. Kim, C. Pépin
We study both the electrical and thermal transport near the heavy-fermion quantum critical point (QCP), identified with the breakdown of the Kondo effect as an orbital selective Mo…
