Interplay between unconventional superconductivity and heavy-fermion quantum criticality: CeCuSi versus YbRhSi
M. Smidman, O. Stockert, J. Arndt +25
In this paper the low-temperature properties of two isostructural canonical heavy-fermion compounds are contrasted with regards to the interplay between antiferromagnetic (AF) quan…
Charge transport in graphene-based mesoscopic realizations of Sachdev-Ye-Kitaev models
Oguzhan Can, Emilian M. Nica, Marcel Franz
We consider a recent proposal for a physical realization of the Sachdev-Ye-Kitaev (SYK) model in the zeroth-Landau-level sector of an irregularly-shaped graphene flake. We study in…
Kondo Destruction and Multipolar Order-- Implications for Heavy Fermion Quantum Criticality
Hsin-Hua Lai, Emilian M. Nica, Wen-Jun Hu +3
Quantum criticality beyond the Landau paradigm represents a fundamental problem in condensed matter and statistical physics. Heavy fermion systems with multipolar degrees of freedo…
Orbital-selective superconductivity in the nematic phase of FeSe
Haoyu Hu, Rong Yu, Emilian M. Nica +2
The interplay between electronic orders and superconductivity is central to the physics of unconventional superconductors, and is particularly pronounced in the iron-based supercon…
