Nuclear spin bath
Web1 apr. 2000 · It is the spin bath analogue of the famous `spin-boson' oscillator model, and describes, e.g., the tunnelling dynamics of nanoscopic and mesoscopic magnets and superconductors. We show how to average over (or `integrate out') spin bath modes, using an operator instanton technique, to find the central spin dynamics. Web28 nov. 2008 · The dynamics of single electron and nuclear spins in a diamond lattice with different 13 C nuclear spin concentration is investigated. It is shown that coherent control of up to three individual nuclei in a dense nuclear spin cluster is feasible. The free-induction decays of nuclear spin Bell states and single nuclear coherences among 13 C nuclear …

One cannot in generalmap a spin bath to an …
WebIn the ionized case, instead, the absence of the electron allows the bath nuclear spins to undergo energy-conserving flip-flop dynamics mediated by their mutual magnetic dipole interaction. Once the electron is reintroduced to take the next run, it is likely to find the bath in a different state from the previous run. WebWhen electrons flow through the device, the electron spins in turn act back on the nuclear spin bath, and cause dynamical nuclear polarization. This sometimes leads to a striking bistable behavior. See also the press release or the article [Science 309, 1346 (2005)].
WebSolid-state spin defects have become a resource for many quantum information protocols and at the same time also a test-bed for demonstrating quantum effects all the way to room temperature [1,2].A key aspect in using these systems for quantum technologies is the hyperpolarization wherein a readily polarizable central (probe) spin transfers to and …
