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 renormalized superperturbation theory (SPT) approach to the Anderson model in and out of equilibrium
Enrique Muñoz, Farzaneh Zamani, Lukas Merker +2
The properties of current-carrying steady states of strongly correlated systems away from the linear-response regime are of topical interest. In this article, we review the renorma…
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…
Non-linear quantum critical dynamics and fluctuation-dissipation ratios far from equilibrium
Farzaneh Zamani, Pedro Ribeiro, Stefan Kirchner
Non-thermal correlations of strongly correlated electron systems and the far-from-equilibrium properties of phases of condensed matter have become a topical research area. Here, an…
Steady-state dynamics and effective temperatures of quantum criticality in an open system
P. Ribeiro, F. Zamani, S. Kirchner
We study the thermal and non-thermal steady state scaling functions and the steady-state dynamics of a model of local quantum criticality. The model we consider, i.e. the pseudogap…
Nonlinear thermoelectric response of quantum dots: renormalized dual fermions out of equilibrium
Stefan Kirchner, Farzaneh Zamani, Enrique Muñoz
The thermoelectric transport properties of nanostructured devices continue to attract attention from theorists and experimentalist alike as the spatial confinement allows for a con…
Quantum criticality in the two-channel pseudogap Anderson model: A test of the non-crossing approximation
Farzaneh Zamani, Tathagata Chowdhury, Pedro Ribeiro +2
We investigate the dynamical properties of the two-channel Anderson model using the noncrossing approximation (NCA) supplemented by numerical renormalization-group calculations. We…
