Dimensionality tuning of heavy-fermion states in ultrathin CeSi2 films
Yi Wu, Weifan Zhu, Teng Hua +18
Dimensionality tuning is an important method to modify the electronic states of quantum materials. However, the mechanism of such tuning in heavy fermion systems and its connection…
Pressure-induced superconductivity beyond magnetic quantum criticality in a Kondo ferromagnet
Yanan Zhang, Yongjun Zhang, Jiawen Zhang +13
Quantum phase transitions are an established setting for emergent phenomena driven by strong electronic correlations, including strange metals and unconventional superconductivity.…
Fermionic Critical Fluctuations: Potential Driver of Strange Metallicity and Violation of the Wiedemann-Franz Law in YbRh2Si2
Frank Steglich
Results of combined thermal and electrical transport measurements through the magnetic field-induced quantum critical point in the heavy-fermion compound YbRh2Si2 are revisited to…
Critical fluctuations and conserved dynamics in a strange ferromagnetic metal
Jin Zhan, Yongjun Zhang, Jiawen Zhang +9
The origin of the strange metallic behavior observed in a wide range of quantum materials is an open challenge to condensed matter physics. Historically, strange metals were unique…
Direction dependent switching of carrier-type enabled by Fermi surface geometry
Shuaishuai Luo, Feng Du, Dajun Su +8
While charge carriers can typically be designated as either electron- or hole- type, depending on the sign of the Hall coefficient, some materials defy this straightforward classif…
Unconventional superconductivity in the Kondo-lattice system CeCuSi -- a personal perspective
Frank Steglich
In the first part of this article, I briefly review early research activities concerning strongly correlated electron systems, beginning with the discovery of superconductivity and…
Evolution of the Kondo lattice and non-Fermi liquid excitations in a heavy-fermion metal
S. Seiro, L. Jiao, S. Kirchner +7
Strong electron correlations can give rise to extraordinary properties of metals with renormalized quasiparticles which are at the basis of Landau's Fermi liquid theory. Near a qua…
Enhancement of the effective mass at high magnetic fields in CeRhIn
L. Jiao, M. Smidman, Y. Kohama +14
The Kondo-lattice compound CeRhIn displays a field-induced Fermi surface reconstruction at T, which occurs within the antiferromagnetic state, prior to the quant…
Evidence for Weyl fermions in a canonical heavy-fermion semimetal YbPtBi
C. Y. Guo, F. Wu, Z. Z. Wu +8
The manifestation of Weyl fermions in strongly correlated electron systems is of particular interest. We report evidence for Weyl fermions in the heavy fermion semimetal YbPtBi fro…
BCS-like superconductivity in the noncentrosymmetric compounds NbRe
J. Chen, L. Jiao, J. L. Zhang +5
We present research on the superconducting properties of NbRe ( = 0.13-0.38) obtained by measuring the electrical resistivity , magnetic susceptibility $χ(T)…
Magnetism and superconductivity driven by identical 4 states in a heavy-fermion metal
Sunil Nair, O. Stockert, U. Witte +8
The apparently inimical relationship between magnetism and superconductivity has come under increasing scrutiny in a wide range of material classes, where the free energy landscape…
Response of the Heavy-Fermion Superconductor CeCoIn to Pressure: Roles of Dimensionality and Proximity to a Quantum-Critical Point
M. Nicklas, R. Borth, E. Lengyel +6
We report measurements of the pressure-dependent superconducting transition temperature and electrical resistivity of the heavy-fermion compound CeCoIn. Pressure moves Ce…
