Abstract

We consider a system of two strongly coupled electron spins in zero magnetic field, each of which is interacting with an individual bath of nuclear spins via the hyperfine interaction. Applying the long-spin approximation that we introduced in a previous paper [ Europhys. Lett. 95 47009 (2011)] (here each bath is replaced by a single long spin), we numerically study the electron spin and ...
