Quantum criticality in the spin-isotropic pseudogap Bose-Fermi Kondo model: entropy, scaling, and the g-theorem
Zuodong Yu, Farzaneh Zamani, Pedro Ribeiro +1
We study the behavior of the entropy of the pseudogap Bose-Fermi Kondo model within a dynamical large- limit, where is related to the symmetry group of the model. This model…
Terahertz Conductivity of Heavy-fermion Systems from Time-resolved Spectroscopy
Chia-Jung Yang, Shovon Pal, Farzaneh Zamani +6
The Drude model describes the free-electron conduction in simple metals, governed by the freedom that the mobile electrons have within the material. In strongly correlated systems,…
Oxygen vacancy-driven orbital multichannel Kondo effect in Dirac nodal line metals IrO2 and RuO2
Sheng-Shiuan Yeh, Ta-Kang Su, An-Shao Lien +5
Strong electron correlations have long been recognized as driving the emergence of novel phases of matter. A well recognized example is high-temperature superconductivity which can…
Fermi volume evolution and crystal field excitations in heavy-fermion compounds probed by time-domain terahertz spectroscopy
Shovon Pal, Christoph Wetli, Farzaneh Zamani +4
We measure the quasiparticle weight in the heavy-fermion compound CeCuAu () by time-resolved THz spectroscopy for temperatures from 2 up to 300\,K. This me…
The Functional Integral formulation of the Schrieffer-Wolff transformation
Farzaneh Zamani, Pedro Ribeiro, Stefan Kirchner
We revisit the Schrieffer-Wolff transformation and present a path integral version of this important canonical transformation. The equivalence between the low-energy sector of the…
