Published: March 2012

We present investigations of the magnetic and electric transport properties, specific heat, and electronic structure of the intermetallic and strongly correlated system of CeRhSn(1-x)In(x) compounds. The main goal of this paper is to determine the hybridization energy between the f electron and conduction electron states, V(cf), and its influence on the ground state properties of the system. The complementary experimental data are discussed on the basis of the Anderson model for a periodic Kondo lattice. CeRhSn is known as a non-Fermi liquid, while CeRhIn is a valence fluctuating system. We discuss the ground state properties of CeRhSn(1-x)In(x) and compare the results with those obtained for the doped Ce-based Kondo insulators.

Unusual violation of the Wiedemann-Franz law at ultralow temperatures in topological compensated semimetals.

Nat Commun

January 2025

Anhui Key Laboratory of Magnetic Functional Materials and Devices, Institutes of Physical Science and Information Technology, Anhui University, Hefei, Anhui, China.

Thermal conductivity and electrical resistivity at ultralow temperatures and high magnetic fields are studied in the topological compensated semimetals TaAs, NbAs, and NdSb. A striking phenomenon is observed where the thermal conductivity shows a T scaling at very low temperatures, while the resistivity shows a T-independent residual term. This indicates a strong violation of the Wiedemann-Franz (WF) law, since the field dependence of κ shows that the low-temperature thermal conductivity is dominated by electronic transport.

Shot Noise in a Metal Close to the Mott Transition.

Nano Lett

December 2024

Department of Physics, Emory University, Atlanta, Georgia 30322, United States.

SrIrO is a metallic complex oxide with unusual electronic and magnetic properties believed to originate from electron correlations due to its proximity to the Mott metal-insulator transition. However, the nature of its electronic state and the mechanism of metallic conduction remain poorly understood. We demonstrate that the shot noise produced by nanoscale SrIrO junctions is strongly suppressed, inconsistent with diffusive quasiparticle transport.

The half-filled lowest Landau level is a fascinating platform for researching interacting topological phases. A celebrated example is the composite Fermi liquid, a non-Fermi liquid formed by composite fermions in strong magnetic fields. Its zero-field counterpart is predicted in a twisted MoTe bilayer (tMoTe)-a recently discovered fractional Chern insulator exhibiting the fractional quantum anomalous Hall effect.

Transport phase diagram and anomalous metallicity in superconducting infinite-layer nickelates.

Nat Commun

November 2024

High Field Magnet Laboratory (HFML-FELIX) and Institute for Molecules and Materials, Radboud University, Toernooiveld 7, 6525 ED, Nijmegen, Netherlands.

Article Synopsis
  • The study investigates whether high-T cuprates and infinite-layer nickelates share similar interactions affecting their normal and superconducting states, highlighting recent advancements in high-quality nickelate crystals.
  • Recent research shows that nickelates have a superconducting dome and comparable transport properties to cuprates, but the normal state behavior in strong magnetic fields needs further exploration.
  • Findings from new NdSrNiO films indicate that the normal-state resistivity in infinite-layer nickelates displays non-Fermi-liquid behavior across various doping levels, suggesting both systems share characteristics of a quantum critical phase despite differences in their charge dynamics.

Short-Range Correlations and Urca Process in Neutron Stars.

Phys Rev Lett

October 2024

Frankfurt Institute for Advanced Studies, D-60438 Frankfurt am Main, Germany and Institute of Theoretical Physics, University of Wroclaw, 50-204 Wroclaw, Poland.

Recent measurements of high-momentum correlated neutron-proton pairs at JLab suggest that the dense nucleonic component of the compact stars contains a fraction of high-momentum neutron-proton pairs that is not accounted for in the familiar Fermi-liquid theory of the neutron-proton fluid mixture. We compute the rate of the Urca process in compact stars taking into account the non-Fermi liquid contributions to the proton's spectral widths induced by short-range correlations. The Urca rate differs strongly from the Fermi-liquid prediction at low temperatures; in particular, the high threshold on the proton fraction precluding the Urca process in neutron stars is replaced by a smooth increase with the proton fraction.
