Geometric Qubits in Programmable Atomic Trimers
Julien Garaud, Antti J. Niemi
Motivated by programmable tweezer arrays, we develop an exactly solvable shape-space theory for near-equilateral atomic trimers. The Higgs oscillator on Kendall's shape sphere give…
Evidence of pseudogap and absence of spin magnetism in the time-reversal-symmetry-breaking state of BaKFeAs
Florian Bärtl, Nadia Stegani, Federico Caglieris +13
Muon-spin-rotation (SR) experiments and the observation of a spontaneous Nernst effect indicate time-reversal symmetry breaking (BTRS) at above the supercon…
Observation of single-quantum vortex splitting in the BaKFeAs superconductor
Q. Z. Zhou, B. R. Chen, B. K. Xiang +12
Since their theoretical discovery more than a half-century ago, vortices observed in bulk superconductors have carried a quantized value of magnetic flux determined only by fundame…
Counterpart of the Chandrasekhar-Kendall state in noncentrosymmetric superconductors
Julien Garaud, Anatolii Korneev, Albert Samoilenka +3
We demonstrate that superconductors with broken inversion symmetry support a family of stable, spatially localized configurations of the self-knotted magnetic field. These solution…
Topological defects and other properties of multicomponent superconductors
Julien Garaud
In recent years, there were a number of experimental developments and discoveries of novel superconducting materials which exhibit multicomponent, many-body degrees of freedom. The…
Effective model and Magnetic Properties of the Resistive Electron Quadrupling State
Julien Garaud, Egor Babaev
Recent experiments [V.~Grinenko {\it et al.} {Nat. Phys. {\bf 17}, 1254 (2021)}; \url{http://doi.org/10.1038/s41567-021-01350-9}] reported the observation of a condensate of four-f…
