Fractional spin Josephson effect in topological spin superconductors
Liang Du, Hua Jiang, Yijia Wu +1
Topological spin superconductors are -wave spin-triplet exciton insulators whose topological edge modes have been shown to obey non-Abelian braiding statistics. Based on a toy m…
Combining Bayesian reconstruction entropy with maximum entropy method for analytic continuations of matrix-valued Green's functions
Songlin Yang, Liang Du, Li Huang
The Bayesian reconstruction entropy is considered an alternative to the Shannon-Jaynes entropy, as it does not exhibit the asymptotic flatness characteristic of the Shannon-Jaynes…
