Two superconducting states with broken time-reversal symmetry in FeSe1-xSx
K. Matsuura, M. Roppongi, M. Qiu +25
Iron-chalcogenide superconductors FeSeS possess unique electronic properties such as non-magnetic nematic order and its quantum critical point. The nature of supercondu…
Tuning the Parity Mixing of Singlet-Septet Pairing in a Half-Heusler Superconductor
K. Ishihara, T. Takenaka, Y. Miao +12
In superconductors, electrons with spin form Cooper pairs whose spin structure is usually singlet () or triplet (). When the electronic structure near the F…
Thermodynamic Signatures of Diagonal Nematicity in RbFeAs Superconductor
Y. Mizukami, O. Tanaka, K. Ishida +10
Electronic nematic states with broken rotational symmetry often emerge in correlated materials. In most iron-based superconductors, the nematic anisotropy is oriented in the Fe-Fe…
Chiral superconductivity in UTe2 probed by anisotropic low-energy excitations
K. Ishihara, M. Roppongi, M. Kobayashi +5
Chiral spin-triplet superconductivity is a topologically nontrivial pairing state with broken time-reversal symmetry, which can host Majorana quasiparticles. The recently discovere…
Disorder-induced topological change of the superconducting gap structure in iron pnictides
Y. Mizukami, M. Konczykowski, Y. Kawamoto +9
In superconductors with unconventional pairing mechanisms, the energy gap in the excitation spectrum often has nodes, which allow quasiparticle excitations at low energies. In many…
Anomalous superfluid density in quantum critical superconductors
K. Hashimoto, Y. Mizukami, R. Katsumata +10
When a second-order magnetic phase transition is tuned to zero temperature by a non-thermal parameter, quantum fluctuations are critically enhanced, often leading to the emergence…
