Persistent dark states in anisotropic central spin models
Tamiro Villazon, Pieter W. Claeys, Mohit Pandey +2
Long-lived dark states, in which an experimentally accessible qubit is not in thermal equilibrium with a surrounding spin bath, are pervasive in solid-state systems. We explain the…

Integrability and dark states in an anisotropic central spin model
Tamiro Villazon, Anushya Chandran, Pieter W. Claeys
Central spin models describe a variety of quantum systems in which a spin-1/2 qubit interacts with a bath of surrounding spins, as realized in quantum dots and defect centers in di…
