Impurity-induced states in conventional and unconventional superconductors
We review recent developments in our understanding of how impurities influence the electronic states in the bulk of superconductors. Our focus is on the quasi-localized states in the vicinity of…
Mott Transition in VO2 Revealed by Infrared Spectroscopy and Nano-Imaging
TLDR
The electronic properties of a prototypical correlated insulator vanadium dioxide in which the metallic state can be induced by increasing temperature is reported, setting the stage for investigations of charge dynamics on the nanoscale in other inhomogeneous correlated electron systems.
Spin current and magnetoelectric effect in noncollinear magnets.
TLDR
A new mechanism of the magnetoelectric effect based on the spin supercurrent is theoretically presented in terms of a microscopic electronic model for noncollinear magnets and applications to the spiral spin structure and the gauge theoretical interpretation are discussed.
Dirac materials
A wide range of materials, like d-wave superconductors, graphene, and topological insulators, share a fundamental similarity: their low-energy fermionic excitations behave as massless Dirac particles…
Superconductivity and quantum criticality in CeCoIn5.
Electrical resistivity measurements on a single crystal of the heavy-fermion superconductor CeCoIn5 at pressures to 4.2 GPa reveal a strong crossover in transport properties near P(*) approximately…
Spectroscopy of spontaneous spin noise as a probe of spin dynamics and magnetic resonance
TLDR
Correlation spectra of the measured spin noise reveal g-factors, nuclear spin, isotope abundance ratios, hyperfine splittings, nuclear moments and spin coherence lifetimes—without having to excite, optically pump or otherwise drive the system away from thermal equilibrium, suggesting a possible route towards non-perturbative, sourceless magnetic resonance of small systems.
Imaging the Fano lattice to ‘hidden order’ transition in URu2Si2
TLDR
The URu2Si2 ‘hidden order’ state emerges directly from the Fano lattice electronic structure and exhibits characteristics, not of a conventional density wave, but of sudden alterations in both the hybridization at each U atom and the associated heavy fermion states.
Interplay of electron–lattice interactions and superconductivity in Bi2Sr2CaCu2O8+δ
Formation of electron pairs is essential to superconductivity. For conventional superconductors, tunnelling spectroscopy has established that pairing is mediated by bosonic modes (phonons); a peak in…
Dynamical magnetoelectric coupling in helical magnets.
TLDR
A theory of collective mode dynamics in the helical magnets coupled to electric polarization via spin-orbit interaction is developed, and role of these low-lying modes in the neutron scattering and antiferromagnetic resonance is revealed.
Band Gap Prediction for Large Organic Crystal Structures with Machine Learning
TLDR
A consistent dataset of 12 500 crystal structures and their corresponding DFT band gap are released and trained models are employed to predict the band gap for 260 092 materials contained within the Crystallography Open Database (COD), made available online so that the predictions can be obtained for any arbitrary crystal structure uploaded by a user.
