Origin of the non-Fermi-liquid behavior in CeRh2As2
P. Khanenko, D. Hafner, K. Semeniuk +11
Unconventional superconductivity in heavy-fermion systems appears often near magnetic quantum critical points (QCPs). This seems to be the case also for CeRh2As2 (Tc 0.31…
Electronuclear Quantum Criticality
J. Banda, D. Hafner, J. F. Landaeta +6
We present here a rare example of electronuclear quantum criticality in a metal. The compound YbCu4.6Au0.4 is located at an unconventional quantum critical point (QCP). In this mat…
Field-angle dependence reveals odd-parity superconductivity in CeRhAs
J. F. Landaeta, P. Khanenko, D. C. Cavanagh +8
CeRhAs is an unconventional superconductor with multiple superconducting phases and K. When , it shows a field-induced transition at $μ_…
Conventional type-II superconductivity in locally non-centrosymmetric LaRhAs single crystals
J. F. Landaeta, A. M. Leon, S. Zwickel +8
We report on the observation of superconductivity in LaRhAs, which is the analogue without -electrons of the heavy-fermion system with two superconducting phases CeRh$_2…
Possible quadrupole density wave in the superconducting Kondo lattice CeRh2As2
D. Hafner, P. Khanenko, E. -O. Eljaouhari +12
CeRh2As2 has recently been reported to be a rare case of multi-phase unconventional superconductor [S. Khim et al., arXiv:2101.09522] close to a quantum critical point (QCP). Here,…
Field-induced transition from even to odd parity superconductivity in CeRhAs
S. Khim, J. F. Landaeta, J. Banda +11
We report the discovery of two-phase unconventional superconductivity in CeRhAs. Using thermodynamic probes, we establish that the superconducting critical field of its hig…
Strong antisymmetric spin-orbit coupling and superconducting properties: The case of noncentrosymmetric LaPtSi
S. Palazzese, J. F. Landaeta, D. Subero +2
In this work we aim to analyze the effect of a strong antisymmetric spin-orbit coupling (ASOC) on superconductivity of noncentrosymmetric LaPtSi. We study the energy gap structure…
Unconventional superconductivity and an ambient-pressure magnetic quantum critical point in single-crystal LaNiC
J. F. Landaeta, D. Subero, P. Machado +2
Superconductivity in noncentrosymmetric LaNiC is expected to be induced by electron--phonon interactions due to its lack of magnetic instabilities. The non-Bardeen-Cooper-Schri…
Superconductivity and quantum criticality in heavy fermions CeIrSi and CeRhSi
J. F. Landaeta, D. Subero, D. Catalá +6
Superconductivity and magnetism are mutually exclusive in most alloys and elements, so it is striking that superconductivity emerges around a magnetic quantum critical point (QCP)…
High-resolution magnetic penetration depth and inhomogeneities in locally noncentrosymmetric SrPtAs
J. F. Landaeta, S. V. Taylor, I. Bonalde +4
We present a magnetic-penetration-depth study on polycrystalline and granular samples of SrPtAs, a pnictide superconductor with a hexagonal structure containing PtAs layers that in…
Evidence of s-wave superconductivity in ternary intermetallic La3Pd4Si4
S. V. Taylor, J. F. Landaeta, D. Subero +3
We measured the temperature dependence of the magnetic penetration depth of La3Pd4Si4 down to 0.02 Tc. We observe a temperature-independent behaviour below 0.25 Tc, which is firm e…
