Architectures for quantum computing based on neutral atoms have risen to prominence as candidates for both near and long-term applications. These devices are particularly well suit…
Multi-impurity chiral Kondo model: correlation functions and anyon fusion rules
Dor Gabay, Cheolhee Han, Pedro L. S. Lopes +2
The multichannel Kondo model supports effective anyons on the partially screened impurity, as suggested by its fractional impurity entropy. It was recently demonstrated for the mul…

It was proposed in [(https://doi.org/10.1103/PhysRevLett.114.145301){Chen et al., Phys. Rev. Lett. , 145301 (2015)}] that spin-2 chains display an extended critical p…
Topological Josephson Bifurcation Amplifier: Semiclassical theory
