Abstract Doping of a Mott insulator gives rise to a wide variety of exotic emergent states, from high-temperature superconductivity to charge, spin, and orbital orders. The physics underpinning their evolution is, however, poorly understood. A major

Abstract We performed polarized reflection and transmission measurements on the layered conducting oxide PdCoO2 thin films. For the a b-plane, an optical peak near Ω ≈ 750 cm−1 drives the scattering rate 1/τ(ω) and effective mass m *(ω) of th

The motion of electrons in the vast majority of conductors is diffusive, obeying Ohm’s law. However, the recent discovery and growth of high-purity materials with extremely long electronic mean free paths has sparked interest in non-Ohmic alternati

Abstract The role of nematic fluctuations for unconventional superconductivity has been the subject of intense discussions for many years. In iron-based superconductors, the most established probe for electronic-nematic fluctuations, i.e. the elastor

Ballistic electron beams in clean metals can be focused by passing currents through well designed contraptions, which is mostly done in isotropic materials described by a circular Fermi surface. Here, the authors demonstrate that the almost hexagonal

When Heisenberg spins interact antiferromagnetically on a triangular lattice and nearest-neighbor interactions dominate, the ground state is 120° antiferromagnetism. In this work, we probe the response of this state to lifting the triangular symmetr

We have carried out Andreev reflection measurements on point contact junctions between normal metal and single crystals of the quasi-one-dimensional (Q1D) superconductor Nb2PdxSe5 (Tc ∼ 5.5 K). The contacts of the junctions were made on either self

We report the discovery of superconductivity with T _c = 5.5 K in Nb _2 Pd _x Se _5 , in which one-dimensional (1D) Nb–Se chains existing along the b -direction hybridize each other to form the conducting b – c * plane. The magnetic susceptibilit
