Abstract We investigate the high-pressure phase of the iron-based superconductor FeSe0.89S0.11 using transport and tunnel diode oscillator studies using diamond anvil cells. We construct detailed pressure-temperature phase diagrams that indicate that

We present band structure calculations and quantum oscillation measurements on LuRh _2 Si _2 , which is an ideal reference to the intensively studied quantum critical heavy-fermion system YbRh _2 Si _2 . Our band structure calculations show a strong

We investigate the electronic structure of the archetypical Mott insulator NiS2 by means of density functional theory calculations in which we explicitly account for the non-collinear antiferromagnetic order, as recently established in the isoelectro

In the vicinity of a quantum critical point, quenched disorder can lead to a quantum Griffiths phase, accompanied by an exotic power-law scaling with a continuously varying dynamical exponent that diverges in the zero-temperature limit. Here, we inve

Fe-based superconductors: Characterizing the nematic phase transition New measurements of quantum oscillations in FeSe1-xSx help understanding the nature of the nematic phase transition in Fe-based superconductors. Nematic order — an electronic ord

The origin of intrinsic quantum criticality in the heavy-fermion superconductor $\beta$-YbAlB$_4$ has been attributed to strong Yb valence fluctuations and its peculiar crystal structure. Here, we assess these contributions individually by studying t

The upper critical field of multiband superconductors is an important quantity that can reveal details about the nature of the superconducting pairing. Here we experimentally map out the complete upper-critical-field phase diagram of a stoichiometric

Understanding superconductivity requires detailed knowledge of the normal electronic state from which it emerges. A nematic electronic state that breaks the rotational symmetry of the lattice can potentially promote unique scattering relevant for sup

The nematic electronic state and its associated critical fluctuations have emerged as a potential candidate for the superconducting pairing in various unconventional superconductors. However, in most materials their coexistence with magnetically orde

Weyl semimetals exhibit exceptional quantum electronic transport due to the presence of topologically-protected band crossings called Weyl nodes. The nodes come in pairs with opposite chirality, but their number and location in momentum space is othe
