Direct evidence for the absence of coupling between shear strain and superconductivity in Sr2RuO4
Giordano Mattoni, Thomas Johnson, Atsutoshi Ikeda +4
The superconducting symmetry of Sr2RuO4 has been intensely debated for many years. A crucial controversy recently emerged between shear-mode ultrasound experiments, which suggest a…
Hydride superconductivity: here to stay
Gregory S. Boebinger, Andrey V. Chubukov, Ian R. Fisher +12
The field of hydride superconductivity has recently been mired in a controversy that might divert attention from the question of central importance: do hydrides support genuine sup…
Pressure evolution of the normal- and superconducting-state properties of the line-nodal material CaSb revealed by Sb nuclear quadrupole resonance
H. Takahashi, S. Kitagawa, K. Ishida +5
CaSb is the Dirac line-nodal material that exhibits a superconducting (SC) transition at 1.7 K. In spite of its conventional SC state at ambient pressure, the transition temper…
In-plane magnetic penetration depth in SrRuO: muon-spin rotation/relaxation study
Rustem Khasanov, Aline Ramires, Vadim Grinenko +6
We report on measurements of the in-plane magnetic penetration depth () in single crystals of SrRuO down to K by means of muon-spin rotation/rela…
Superconductivity studied by solving ab initio low-energy effective Hamiltonians for carrier doped CaCuO, BiSrCuO, BiSrCaCuO, and HgBaCuO
Michael Thobias Schmid, Jean-Baptiste Morée, Ryui Kaneko +2
We numerically analyze superconductivity (SC) in the cuprate superconductors by using ab initio effective Hamiltonians consisting of the antibonding combination of Cu $3d_{x^2-y^2}…
SR measurements on SrRuO under uniaxial stress
Vadim Grinenko, Rajib Sarkar, Shreenanda Ghosh +10
Muon spin rotation/relaxation (SR) and polar Kerr effect measurements provide evidence for a time-reversal symmetry breaking (TRSB) superconducting state in SrRuO. Howev…
Spontaneous superconducting diode effect in non-magnetic Nb/Ru/SrRuO topological junctions
M. S. Anwar, T. Nakamura, R. Ishiguro +5
Non-reciprocal electronic transport in a material occurs if both time reversal and inversion symmetries are broken. The superconducting diode effect (SDE) is an exotic manifestatio…
Pseudogap in electron-doped cuprates: Strong correlation leading to band splitting
M. Horio, S. Sakai, H. Suzuki +10
The pseudogap phenomena have been a long-standing mystery of the cuprate high-temperature superconductors. The pseudogap in the electron-doped cuprates has been attributed to band…
Thermal Expansion of the Heavy-fermion Superconductor PuCoGa
R. Eloirdi, C. Giacobbe, P. Amador Celdran +6
We have performed high-resolution powder x-ray diffraction measurements on a sample of PuCoGa, the heavy-fermion superconductor with the highest critical temperature…
Intrinsic Angular Momentum and Intrinsic Magnetic Moment of Chiral Superconductor on Two-Dimensional Square Lattice
Atsushi Tsuruta, Susumu Yukawa, Kazumasa Miyake
The intrinsic magnetic moment (IMM) and intrinsic angular momentum (IAM) of a chiral superconductor with -wave symmetry on a two-dimensional square lattice are discussed on the…
Spin Polarization Enhanced by Spin-Triplet Pairing in SrRuO Probed by NMR
K. Ishida, M. Manago, T. Yamanaka +4
We report a novel phenomenon intimately related to the spin-triplet superconductivity. It is well known that the spin susceptibility decreases below the superconducting transition…
Ginzburg-Landau Formalism for 2n-Body Condensation
Atsuhi Tsuruta, Shinya Imamura, Kazumasa Miyake
The Ginzburg-Landau formalism is constructed for Fermi superfluidity based on the 2n-body condensation in parallel with the usual Ginzburg-Landau formalism for the Cooper pair cond…

Hiroki Takahashi, Akira Sugimoto, Yusuke Nambu +13
All the iron-based superconductors identified to date share a square lattice composed of Fe atoms as a common feature, despite having different crystal structures. In copper-based…
BCS-BEC Crossover in Two-Dimensional Attractive Hubbard Model under Magnetic Field
Atsushi Tsuruta, Satoshi Hyodo, Kazumasa Miyake
The Bardeen-Cooper-Schrieffer (BCS)-Bose-Einstein condensation (BEC) crossover in the two-dimensional attractive Hubbard model under the magnetic field is discussed at the half-fil…
Theory of Pairing Assisted Spin Polarization in Spin-Triplet Equal Spin Pairing: Origin of Extra Magnetization in Sr_2RuO_4 in Superconducting State
Kazumasa Miyake
It is shown that an extra magnetization is induced by an onset of the equal-spin-pairing of spin triplet superconductivity if the energy dependence of the density of states of quas…
