Query: Spin-orbit coupled particle in a spin bath   We consider a spin-orbit coupled particle confined in a quantum dot in a bath
of impurity spins. We investigate the consequences of spin-orbit coupling on
the interactions that the particle mediates in the spin bath. We show that in
the presence of spin-orbit coupling, the impurity-impurity interactions are no
longer spin-conserving. We quantify the degree of this symmetry breaking and
show how it relates to the spin-orbit coupling strength. We identify several
ways how the impurity ensemble can in this way relax its spin by coupling to
phonons. A typical resulting relaxation rate for a self-assembled Mn-doped ZnTe
quantum dot populated by a hole is 1 $\mu$s. We also show that decoherence
arising from nuclear spins in lateral quantum dots is still removable by a spin
echo protocol, even if the confined electron is spin-orbit coupled.
