Field-angle dependence reveals odd-parity superconductivity in CeRh $_{2}$ As $_{2}$

J. F. Landaeta, P. Khanenko, D. C. Cavanagh +8

CeRh $_{2}$ As $_{2}$ is an unconventional superconductor with multiple superconducting phases and $T_{c} = 0.26$ K. When $H ∥ c$ , it shows a field-induced transition at $Î¼…

The phase diagram of CeRh $_{2}$ As $_{2}$ for out-of-plane magnetic field

P. Khanenko, J. F. Landaeta, S. Ruet +10

The heavy-fermion superconductor CeRh $_{2}$ As $_{2}$ ( $T_{c} = 0.35 K$ ) shows two superconducting (SC) phases, SC1 and SC2, when a magnetic field is applied para…

Investigation of CeRh $_{2}$ As $_{2}$ order parameters via ultrasound propagation anomalies

S. Galeski, C. Lee, F. Bartl +11

Unconventional superconductors with nearly degenerate pairing states are rare. CeRh $_{2}$ As $_{2}$ has recently emerged as one of the few existing multi-phase superconductors. It exhibi…

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 Spin Excitations in the Spin-1/2 Triangular-Lattice Antiferromagnet CsYbSe $_{2}$

Tao Xie, Jie Xing, S. E. Nikitin +7

A layered triangular lattice with spin-1/2 ions is an ideal platform to explore highly entangled exotic states like quantum spin liquid (QSL). Here, we report a systematic in-field…

Complete field-induced spectral response of the spin-1/2 triangular-lattice antiferromagnet CsYbSe $_{2}$

Tao Xie, A. A. Eberharter, Jie Xing +14

Fifty years after Anderson's resonating valence-bond proposal, the spin-1/2 triangular-lattice Heisenberg antiferromagnet (TLHAF) remains the ultimate platform to explore highly en…

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 $\approx$ 0.31…
