Analytic "Newton's cradles" with perfect transfer and fractional revival
arXiv:2108.09386 · doi:10.1016/j.aop.2022.168790
Abstract
Analytic mass-spring chains with dispersionless pulse transfer and fractional revival are presented. These are obtained using the properties of the para-Racah polynomials. This provides classical analogs of the quantum spin chains that realize important tasks in quantum information: perfect state transfer and entanglement generation.
