Multi-band description of the upper critical field of bulk FeSe
M. Bristow, A. Gower, J. C. A. Prentice +6
The upper critical field of multi-band superconductors can be an essential quantity to unravel the nature of superconducting pairing and its interplay with the electronic structure…
Unconventional localization of electrons inside of a nematic electronic phase
L. Farrar, Z. Zajicek, A. B. Morfoot +6
The magnetotransport behaviour inside the nematic phase of bulk FeSe reveals unusual multiband effects that cannot be reconciled with a simple two-band approximation proposed by su…
The drastic effect of the impurity scattering on the electronic and superconducting properties of Cu-doped FeSe
Z. Zajicek, S. J. Singh, H. Jones +6
Non-magnetic impurities in iron-based superconductors can provide an important tool to understand the pair symmetry and they can influence significantly the transport and the super…
Strain-tuning of nematicity and superconductivity in single crystals of FeSe
Michele Ghini, Matthew Bristow, Joseph C. A. Prentice +4
Strain is a powerful experimental tool to explore new electronic states and understand unconventional superconductivity. Here, we investigate the effect of uniaxial strain on the n…
Robustness of superconducting properties to transition metal substitution and impurity phases in Fe1-xVxSe
Franziska K. K. Kirschner, Daniel N. Woodruff, Matthew J. Bristow +4
We have performed transverse- and zero-field muon spin rotation/relaxation experiments, as well as magnetometry measurements, on samples of Fe1-xVxSe and their Li+NH3 intercalates…

Quantum oscillations probe the Fermi surface topology of the nodal-line semimetal CaAgAs
Y. H. Kwan, P. Reiss, Y. Han +6
Nodal semimetals are a unique platform to explore topological signatures of the unusual band structure that can manifest by accumulating a nontrivial phase in quantum oscillations.…
Suppression of superconductivity and enhanced critical field anisotropy in thin flakes of FeSe
Liam Farrar, Matthew Bristow, Amir A. Haghighirad +3
FeSe is a unique superconductor that can be manipulated to enhance its superconductivity using different routes while its monolayer form grown on different substrates reaches a rec…
Anomalous high-magnetic field electronic state of the nematic superconductors FeSeS
M. Bristow, P. Reiss, A. A. Haghighirad +7
Understanding superconductivity requires detailed knowledge of the normal electronic state from which it emerges. A nematic electronic state that breaks the rotational symmetry of…
Quenched nematic criticality separating two superconducting domes in an iron-based superconductor under pressure
P. Reiss, D. Graf, A. A. Haghighirad +5
The nematic electronic state and its associated nematic critical fluctuations have emerged as potential candidates for superconducting pairing in various unconventional superconduc…
An ideal Weyl semimetal induced by magnetic exchange
J. -R. Soh, F. de Juan, M. G. Vergniory +15
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 oppos…
