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 superco…

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…
