Vison crystals, chiral and crystalline phases in the Yao-Lee model
Muhammad Akram, Emilian Marius Nica, Yuan-Ming Lu +1
We study the phase diagram of the Yao-Lee model with Kitaev-type spin-orbital interactions in the presence of Dzyaloshinskii-Moriya interactions and external magnetic fields. Unlik…
Unconventional fully-gapped superconductivity in the heavy-fermion metal CeCuSi
Michael Smidman, Oliver Stockert, Emilian M. Nica +4
The heavy-fermion metal CeCuSi was the first discovered unconventional, non-phonon-mediated superconductor, and for a long time was believed to exhibit single-band -wave…
Magnetic fragmentation and fractionalized Goldstone modes in a bilayer quantum spin liquid
Aayush Vijayvargia, Emilian Marius Nica, Roderich Moessner +2
We study the phase diagram of a bilayer quantum spin liquid model with Kitaev-type interactions on a square lattice. We show that the low energy limit is described by a -flux Hu…
Multiple superconducting phases in heavy-fermion metals
Emilian M. Nica, Sheng Ran, Lin Jiao +1
Symmetry breaking beyond a global U(1) phase is the key signature of unconventional superconductors. As prototypical strongly correlated materials, heavy-fermion metals provide ide…
Kitaev spin-orbital bilayers and their moiré superlattices
Emilian Nica, Muhammad Akram, Aayush Vijayvargia +2
We determine the phase diagram of a bilayer, Yao-Lee spin-orbital model with inter-layer interactions (J), for several stackings and moiré superlattices. For AA stacking, a gapped…
Multiorbital spin-triplet pairing and spin resonance in the heavy-fermion superconductor
Lei Chen, Haoyu Hu, Christopher Lane +3
The heavy-fermion system is a candidate for spin-triplet superconductivity, which is of considerable interest to quantum engineering. Among the outstanding issues…
