Magneto-elastic coupling in Fe-based superconductors
S. -F. Wu, W. -L. Zhang, V. K. Thorsmølle +12
We used polarization-resolved Raman scattering to study the magneto-elastic coupling in the parent compounds of several families of Fe-based superconductors (BaFe2As2, EuFe2As2, Na…
Tuning the pairing interaction in a -wave superconductor by paramagnons injected through interfaces
M. Naritsuka, P. F. S. Rosa, Y. Luo +9
Unconventional superconductivity and magnetism are intertwined on a microscopic level in a wide class of materials. A new approach to this most fundamental and hotly debated issue…
Emergent exotic superconductivity in artificially-engineered tricolor Kondo superlattices
M. Naritsuka, T. Ishii, S. Miyake +7
In the quest for exotic superconducting pairing states, the Rashba effect, which lifts the electron-spin degeneracy as a consequence of strong spin-orbit interaction (SOI) under br…
Two distinct superconducting pairing states divided by the nematic end point in FeSeS
T. Hanaguri, K. Iwaya, Y. Kohsaka +5
Unconventional superconductivity often competes or coexists with other electronic orders. In iron-based superconductors, relationship between superconductivity and the nematic stat…
Quadrupolar charge dynamics in the nonmagnetic FeSeS superconductors
W. -L. Zhang, S. -F. Wu, S. Kasahara +3
We use polarization-resolved electronic Raman spectroscopy to study charge dynamics in non-magnetic FeSeS superconductor. We observe two features of the quadrupole…
Unusual thermal Hall effect in a Kitaev spin liquid candidate -RuCl
Y. Kasahara, K. Sugii, T. Ohnishi +8
The Kitaev quantum spin liquid displays the fractionalization of quantum spins into Majorana fermions. The emergent Majorana edge current is predicted to manifest itself in the for…
Magnetic and superconducting properties of the heavy-fermion CeCoIn5 epitaxial film probed by nuclear quadrupole resonance
Takayoshi Yamanaka, Masaaki Shimozawa, Hiroaki Shishido +6
Since the progress in the fabrication techniques of thin-films of exotic materials such as strongly correlated heavy-fermion compounds, microscopic studies of the magnetic and elec…
Impact of Disorder on the Superconducting Phase Diagram in BaFe(AsP)
Yuta Mizukami, Marcin Konczykowski, Kohei Matsuura +4
In many classes of unconventional superconductors, the question of whether the superconductivity is enhanced by the quantum-critical fluctuations on the verge of an ordered phase r…
Thermodynamic evidence for nematic phase transition at the onset of pseudogap in YBaCuO
Y. Sato, S. Kasahara, H. Murayama +8
A central issue in the quest to understand the superconductivity in cuprates is the nature and origin of the pseudogap state, which harbours anomalous electronic states such as Fer…
Highly Anisotropic Superconducting Gap in Nematically Ordered and Tetragonal Phases of FeSeS
Y. Sato, S. Kasahara, T. Taniguchi +5
FeSe has a unique ground state in which superconductivity coexists with a nematic order without long-range magnetic ordering at ambient pressure. Here, to study how the pairing int…
Weakening of the diamagnetic shielding in FeSeS at high pressures
K. Y. Yip, Y. C. Chan, Q. Niu +6
The superconducting transition of FeSeS with three distinct sulphur concentrations was studied under hydrostatic pressure up to 70 kbar via bulk AC susceptibi…
Maximizing Tc by tuning nematicity and magnetism in FeSe1-xSx superconductors
K. Matsuura, Y. Mizukami, Y. Arai +19
A fundamental issue concerning iron-based superconductivity is the roles of electronic nematicity and magnetism in realising high transition temperature (). To address t…
Fully gapped superconductivity with no sign change in the prototypical heavy-fermion CeCu2Si2
T. Yamashita, T. Takenaka, Y. Tokiwa +16
In exotic superconductors including high- copper-oxides, the interactions mediating electron Cooper-pairing are widely considered to have a magnetic rather than the convention…
